Let’s look at some ways G/5 Five-Minute-Adhesive can be used around the house for everything from furniture repair to building model railroads.

Composites are a blend of resin (in this case mixed epoxy) and reinforcing fiber. Folks often ask, “How strong are they?” It is difficult to answer this question due to many variables including resin type, fiber type, fiber orientation, and resin/fiber ratio. To give a value for a laminate, we reduce the variables. Values shown in this article were done with test samples using WEST SYSTEM 105 Epoxy Resin®/206 Slow Hardener® at room temperature (70°F). Reinforcing fibers are Episize™ materials. Continue reading
Above: Introducing Six10 Thickened Epoxy Adhesive, a two-part adhesive in a convenient, self-metering cartridge for permanent, waterproof structural gap filling and gluing.
Six10® Adhesive gives you the strength and reliability of a two-part WEST SYSTEM epoxy with the convenience of a single-part product. Six10 is dispensed with a standard caulking gun. Non-sagging Six10 bonds tenaciously to wood, metals, fiberglass, and concrete. Continue reading
WEST SYSTEM® Six10 is a two-part, pre-thickened epoxy adhesive formulated with properties that make it perfect for many adhesive applications. Compared to other ready-to-dispense adhesives, its particular physical properties make it ideal for stitch and glue boat construction, fiberglass laminate repair and general bonding. This new formulation has a good balance between the elongation and toughness of G/flex® and the strength and stiffness of our 105 Resin-based epoxies. You can use it with as many materials as possible including wood, metals and composites. The long working time with fast thru-cure and unique shear thinning are additional characteristics formulated into Six10 that contribute to its ease of use. Continue reading
The WEST SYSTEM® Six10 epoxy cartridge is comprised of the cartridge body, removable nose plug, and a threaded retaining nut. A 600 static mixer is included with the cartridge. (It’s called a static mixer because it has no moving parts.) The cartridge fits into any standard caulk gun—manual, cordless, or pneumatic—and allows simultaneous dispensing and mixing of the two-part epoxy.

By now most of you know that we are the manufacturers of WEST SYSTEM® Epoxy. But you may not know what is involved in the manufacturing and more specifically, the formulating of WEST SYSTEM. It’s not just slapping some chemicals together and then packaging it up into a pretty box. To date, we have performed thousands of tests and generated thousands of test results. Continue reading
Above: This joint style in an edge-glued, 1/8″ thick HDPE plastic strip which holds tight when deflected and is a good choice when gluing plastics.
One of our goals for G/flex® was the ability to bond to a variety of plastics. This was an ambitious goal because plastics historically have been used as mold release surfaces for epoxy, allowing the epoxy to release from the plastic when cured. While developing G/flex, we tested adhesion to a number of plastics with a variety of surface prep methods. Continue reading
D-ring pads are often attached to flexible surfaces with urethane adhesives to gain load-carrying capacity where there otherwise wouldn’t be any. They are used on waterproof fabric cargo bags, heavy tarpaulins, and inflatable boats. They are also sometimes used on the decks of canoes and kayaks to hold cargo in place on long trips. D-rings are not typically used on polyethylene canoes and kayaks because the urethane glues are not recommended for use on HDPE (high-density polyethylene) plastic. We experimented with gluing D-ring pads with G/flex 655 Thickened Epoxy Adhesive to HDPE plastic with that end-use in mind. Continue reading
It all started when I got a tech call from somebody asking if WEST SYSTEM® 105/206 would accept a nail pounded into it, after it was cured, with no pilot hole. I confidently said that it would not work well and in most cases, it would fracture the epoxy. Just for fun, I went out in the shop and tried it because even though we all pretty much agreed it wouldn’t work, nobody had ever actually done it. Well, we were right—the nail caused a “brittle” failure. Continue reading
Above: Mixing G/flex with other WEST SYSTEM Epoxies increases the versatility of these epoxy systems.
WEST SYSTEM 105 Resin-based epoxy is a very versatile system. For years, experienced users have been mixing and blending the various product combinations in countless ways. For example, users may blend 205 Fast Hardener and 206 Slow Hardener to make a hardener with a modified cure speed. Different uses of 410 Microlight® Fairing Filler provide a further example. Many customers assume that the only use of 410 is to make a fairing compound—it is added to thicken epoxy to a peanut butter consistency to create a light, easily-sanded filler. Continue reading
