Thixotropic Injection Resin Making sure the specified anchor is then obtained and installed by a trained installer should make sure the application benefits from the Pros and doesnt suffer from the Cons. Once it has set rock hard you can then go ahead and complete the job. The earliest type of resin anchor (introduced into the UK in 1970 from Germany) carried all the chemical components (resin, aggregate and catalyst) within a capsule originally of glass now sometimes of less fragile foil. We are a small company manufacturing window shutters that has an affinity with the beautiful country that is France. Because chemical anchors flow into the hole they allow for an infinite combination of diameters of fixing and setting depths, and provide a far greater surface area which spreads the load more evenly and re-enforces the fixing area. Do I Need Conventional Or Chemical Fixings For My Diy Project? Injection Resin Slow Set from the bottom of the hole to about half Chemical fixing solutions for heavy-duty fixings in concrete and masonry. Call us on 01626 872886 for Free Advice. Some manufacturers have developed faster curing systems bringing curing times for capsules (for use with special anchor rods in cracked concrete) down to as little as a matter of minutes and injection systems, for general purpose anchoring, to half the standard times while still being slower than standard capsules. Proprietary brushes are available or you can use air, by blowing down a tube (dont suck, close your eyes and wear a dust mask and eye protection) or using a compressor. Anchors and dowels Your email address will not be published. Luckily the design of the tube which chemical fix comes in is that no mixing is required. Various applicator skeleton guns are available, depending upon which resin you choose. Each tube contains two separate plastic bags: resistance to weathering. Securing anchor bolts, Rebar If they are aware of the above Pros and Cons they can make a choice between alternative anchor types that is appropriate to the particular application. nature of our systems minimises expensive on-site delays. The closest mechanical anchors get to this degree of flexibility is that many types of throughbolt are available in a variety of lengths catering not just for different fixture thicknesses, but for different embedment depths and therefore loads as well. Undercut anchors as such dont work well in masonry so must be considered for concrete only. You will find that you will need to stock less variety. It also means that expansion anchors are frequently unsuitable for use in weaker base materials such as brickwork, stonework and especially, blockwork where they would simply crack or crush. SDS or Special Direct System was developed by Hilti and Bosch in 1975. Apart from the cost of resins, which varies hugely, there is setting equipment to buy and the time spent installing is usually longer as they require more care. Clicking on a blue Product total mixed volume is about 280cc. * Epoxy Also learn about the different types of resin available. Dowels, for reinforcement or joining are available in high tensile plated steel or epoxy-glass in 6 25mm diameters. Because of this the mounting of shutters using expanding bolts is ill-advised. AVAILABLE - BUY IN BOXED QUANTITIES, ALL ORDERS GO If buying an electric drill look for a minimum of 2KG impact force in masonry. side dual piston skeleton gun, 6. 2. Chemical Fix is a polyester resin. Whilst self-tapping screw anchors also introduce much lower stresses into the base material during installation and can be very strong in concrete, and work well in masonry, they dont offer such high strengths as chemical anchors and are best suited to temporary or short term applications. Capsule systems have always been less sensitive than injection systems to poor hole cleaning as the spinning action, together with the chunky aggregate, tends to draw some of the dust left on the sides of the hole into the mix, whereas injection systems simply lay the resin against any dust left behind. A more convenient and easier to use packaging format, available on some anchorset products, is the twin bag system, where the contents are contained in two separate polythene bags in a one piece cartridge that allows application using a standard sealant cartridge gun; and also provides a much easier flow. The curing time is the other bugbear of resin anchors whereas mechanical anchors may be loaded immediately. This type of chemical anchor would typically achieve 67kN pull out strength on an M12 threaded rod in solid concrete. only what you need. When we equip our tool kits we are hit with an abundance of options. The main Cons afflicting mechanical anchors relate to expansion types and derive from that characteristic.

Set the tape at a distance from the tube end to allow for the resin that will be displaced by the bar. Will joined Fastener + Fixing Magazine in 2007 and over the last 15 years has experienced every facet of the fastener sector - interviewing key figures within the industry and visiting leading companies and exhibitions around the globe. Chemical fixings are the fixing solution for transferring extreme loads in concrete, aerated concrete or masonry expansion-free. Slow Set - 2.5 hours at 20C - inject Thixotropic This product has a multitude of uses. The information you need may be in the Project below, but if not call them for expert, unbiased assistance with building products. Our anchor adhesives can be provided as epoxy anchor or polyester For these applications injection resin systems were developed and have largely displaced capsule systems in concrete too. The mixing of the hardener and the resin is done in the novel and this does not happen until you apply pressure to the handle of the mastic gun. This sideways motion will put some strain on your drill so dont use excessive force. Required fields are marked *. Next Day Delivery - Nationally, by T.N.T. Studs are generally available in 8, 10 and 12mm sizes. As to their Pros mechanical anchors are usually cheaper as an installed fixing than chemicals; they are far less sensitive to poor installer technique; they can be loaded immediately; and some of them (throughbolts and sleeve anchors) may usefully be fixed through the clearance holes in the fixture whereas most resin anchors require larger clearance holes to facilitate this. The chemical fix is actually just a polyester resin with an aggregate. Long-life - All the cartridges skeleton gun. This Red plug is ideal for 4mm 4.5mm & 5mm diameter screws. and threaded bar into pre-drilled holes in masonry. Slow Set - 400cc - fits our professional standard In my experience, these expanding bolts are only good in a solid cast wall or concrete slab. In fact, the mixing of the two parts required for a chemical fix is done in the nozzle. side dual piston skeleton gun, 3:1 concentric Helical Bar and carbon rods for doweling, When using a chemical fix adhesive you are required how to drill a hole larger than the metal object us to fix into it. Chemical fixings are the fixing solution for transferring extreme loads in concrete, aerated concrete or masonry expansion-free. For the purposes of this project we will show you how to use chemical fixings or resin anchors as they are sometimes known.Gate hinge chemically fixed, Four easy stages complete this operation and all tools and materials are available atwww.epoxy-info.co.uk. The pintle will be mounted to close to the edge and expanding bolts will fail. The most common rawl plug is the RED and in most cases require a 5.5mm masonry TCT drill bit.

The Resin requires a specialist applicator gun, and a wire brush is recommended on smoother substrates to allow better adhesion.The tube is supplied with a mixer nozzle, eliminating the need to mix mortar on site. I would use a 16mm sds masonry drill and drill 2 holes. (See link abbove). in high chemical and vibration resistance of the anchor and resin. Rawl plugs are probably the most used form of wall fixing but there are other methods that would probably suit your particular situation. Inject gently, slowly removing the tube from the hole, to deposit resin without trapping air. Theres only one real problem with mechanical anchors, without which there might be no need for chemical anchors. You may not know what chemical fix is? The Forgefix Resin injection system offers an easy fixing capability for numerous applications. Then there are resins that may be installed at temperatures as low as -20C while others are OK in hollow masonry down to -5C but limited to above +5C in solid masonry. The technical storage or access that is used exclusively for statistical purposes. The expansion of the anchor against the sides of the hole induces compression stresses in the base material and there needs to be enough base material around the anchor to withstand those stresses. here to go to our Shopping Pages, * Structural connections transferring columns, * Tying back existing masonry The technical storage or access is required to create user profiles to send advertising, or to track the user on a website or across several websites for similar marketing purposes. It was surprising how tight you could tighten a nut. - high bond strength and excellent Additional electricity needs are supplemented by. is stronger than the main substrate. surfaces together. An injection resin of the same basic resin may take typically four times as long. This website uses Cookies. Close-edge fixings - Our resin The flexibility in resin anchor selection referred to above comes from the scope to design the anchor to use a bond length between 4 and 20 times the anchor diameter (this is best facilitated by injection systems) and to specify a different rod strength. a two part, styrene free, high strength polyester resin adhesive. If you need to use a more substantial screw? Technical Author, Thixotropic These were, and still are, very effective in concrete, but they dont work too well in masonry materials where resin can be lost in the voids caused by frogs (the V shaped depression in some bricks), in perforations and in the empty gaps between the leaves of solid brickwork. I need to get something off my chest here. Convenience - Our systems avoid are re-sealable minimising waste. They have special characteristics for uses like rebar anchoring, which justify having to wait this long. us for free technical advice. If you have to use these expanding bolt pintels then drill the hole at 45 so the stress of the expansion is deeper into the stone or brick. high loads into slim columns, * Fixing sanitary-ware to hollow This multiplicity of formulations and the wide variations in such parameters causes huge confusion among users so the best advice for contractors is to recommend that, as far as possible, they should choose one system that suits their uses and stick to it and have their installers trained in the correct installation methods for each different resin system they use. our professional standard skeleton A general purpose economical resin based on styrene, recommended for external use due to its hazardous nature. Keep up to date with our DIY projects, tips and latest deals, DIY Doctor Ltd 2022 All Rights Reserved. BULK DISCOUNTS dual piston skeleton gun. The real usefulness is clear when trying to anchor fittings into loose stone walls and soft red bricks. Reliability - Accurate 'self-mixing' Chemical anchors are usually based on a two part product, combining a resin and hardener packed together in the required ratio to provide rapid curing (usually 10 parts resin to one part hardener). Full tables of relevant hole diameter sizes and loading strengths can usually be found on all packs and technical data, but for example for an M8 fixing a 10mm diameter hole would normally be used in concrete. But it is the increased flexibility in the selection of resin anchors that has meant that, in most applications where loads need to be transferred into restricted sections of concrete or via a base plate of restricted dimensions, a resin system will provide a solution where a mechanical anchor, either expansion or undercut, just wont. Chemical versus mechanical anchors the pros and cons. gun, 2.

Polyester 380P - concentric This should be stated on the resin container. You may already have the basic 300cc and/or 400cc skeleton guns, which are used with the Ultra Thixotropic Range, for example.Pure Epoxy it mixes in the nozzle ideal for anchoring bolts and barsPolyester Anchor Resin faster than Epoxies ideal for rapid anchor setting, Pure Epoxy it mixes in the nozzle ideal for anchoring bolts and bars, Polyester Anchor Resin faster than Epoxies ideal for rapid anchor setting. provide excellent results in underwater applications. The only way I have found to remove ironmongery that has been secured using chemical fix is with an angle grinder. or chemical anchor resins, are used to secure anchor bolts, starter bars, The next size to the Red is the Brown. THIXO RAPID ANCHOR RESIN is Natural stone like you will find in France making window reveals has a grain. Those responsible for choosing fixings for any application let alone ones that are safety critical are faced with a bewildering array of fixing systems to choose from and one of the most significant decisions, usually made very quickly by those with experience, is that between chemical and mechanical anchors. I find chemical fix such a practical solution for the mounting of the shutter hinge pins or pintels. This type of chemical anchor would typically achieve 67kN pull out strength on an M12 threaded rod in solid concrete. (Hons. For accurate, waste free injection pre-mark the tube with tape, so that you can stop operating the trigger when the tape appears. Natural stone is not a good material for the fixing into using expanding bolts. They are much more sensitive to poor hole cleaning than mechanical anchors and must be allowed to cure before they can be tightened or loaded. So weve established that resin systems can be stronger, work at closer edge and spacing dimensions, and offer a solution for masonry. Cartridge. After much experience using Chemical fix, I am a convert. Make sure that the tape goes over the part required to take the nut, to avoid resin contamination, which might block the threads. Working ethically is important to us. Don't fancy doing this project yourself? The beauty is that chemical fix resin type bonding agents is that the chemical fix not only sticks to the sides of the hole but locks behind the stone or brick. OUT SAME DAY - GUARANTEED. a 16 mm hole was drilled and the chemical anchoring solution was squeezed in. I frequently see resin anchors (and self-tappers and undercuts) referred to in brochures and on websites as being stress free fixings which can be placed close to edges and to each other. Resin capsule FHB II-P / FHB II-PF HIGH SPEED, Injection mortar FIS V, FIS VS LOW SPEED, FIS VW HIGH SPEED, Injection mortar FIS VL, FIS VL HIGH SPEED. Drill an oversized hole Don't want to do this job yourself? Chemical anchors (I prefer the simpler term resin anchors) exert no setting stresses in the base material so can be specified at closer edge and spacing distances in concrete and will usually develop the strongest anchorage in masonry materials which are their main Pros. 1. The hole is drilled to the required diameter dependent upon the threaded bar to be used, and the loading it has to take. Rawl plugs are good for mounting fixed items to walls. fischer has a unique competence in developing and manufacturing chemical fixing solutions. At the other end of the scale pure epoxy resins can take between 170 hours and 7 hours over the same temperature range and some wont cure below +5C. 3. Check box to confirm you've read and agree to our Privacy Policy. If the wall is in poor condition the plastic rawl plug can pull out. skeleton gun, 3. fischer has a unique competence in developing and manufacturing chemical fixing solutions. systems put minimal stress on the main substrate allowing anchors to be The Cheap drill has an impact that is too short and more of a vibration than the SDS. Traditional products use a co-axial cartridge where the resin is packed into a cartridge which contains a central inner section that holds the hardener. If you need help with any type of Epoxy or Polyester Resin anchor, filler or coating problem Property Repair Systems will be pleased to give you completely free, no obligation advice on 01626 872 650. This allows an optimum and secure solution to be offered for all applications, even under extreme construction site conditions such as wet, cold or heat: approved systems with resin capsules, injection mortars, threaded rods, internal threaded rods, anchor sleeves, accessories and processing equipment. As we work through the Pros and Cons of resin anchors I will highlight the differences between these two distinct systems. In the former the specially shaped threaded anchor rod (or internally threaded socket) must be spun into the capsule, smashing it and mixing the contents in the process using a drilling machine via a drive adaptor. Contact Consult their experts for anchor bonding, stitching masonry and doweling or pinning. For many years I have used chemical fix. The resin goes very hard, binding the thread to the masonry and leaving a short length of thread sticking out onto which you can bolt your ornament, gate post, bracket or aerial for example. 44 product families and 700 variants found. dual piston skeleton gun, Click be used for horizontal, vertical and overhead applications. Buy Now for The SDS has a specific method of producing the percussion impact. Signing up to fastenerandfixing.com enables you to manage your account details. The way to get over this is to use chemical fixings or resin anchors injected into a pre-drilled hole. But in a safety critical application this is probably a small extra cost to pay in relation to the whole job. A section, or stud, of threaded bar is then screwed and bonded into the hole. Like silicone mastic you just need to remove the end of the tube and insert into a mastic gun one. Policy | Returns Policy I Resins for anchoring. for anchoring bolts or studs, 1. If you need to fix close to the edge of a brick or stone pier because you need to hang a gate or fix a letterbox or nameplate, drilling and using screws and bolts which expand in their associated wall plugs may crack or split the masonry. The mixing of the chemical fix is not labour intensive. Manufacturers have been working hard on these aspects. placed in areas where mechanical systems would cause cracking and failure This allows an optimum and secure solution to be offered for all applications, even under extreme construction site conditions such as wet, cold or heat: approved systems with resin capsules, injection mortars, threaded rods, internal threaded rods, anchor sleeves, accessories and processing equipment.
