It’s how they make custom o rings (how I’m gonna make the seals for my cowl covers). 206 Slow Hardener and 207 Special Clear Hardener should not be used below 16°C unless you elevate the working temperature to allow the system to cure properly. Building an Oven Gold Coast had to design, build, and utilize large custom ovens for each section of yacht frame that needed high-temperature exposure. A high strength, easy to use, epoxy system. Initial cure indicates the amount of time before a thin film or coating of curing epoxy can be handled. The #205 fast-cure hardener has a working time of about 60 to 70 minutes at 70°F (20°C) with a minimum cure temperature of 40°F (4°C). Our polymer compounds are formulated to meet challenging physical strength requirements. The hardener provides a long open time but has fast thru-cure. Delivering high shear strength, we designed this epoxy adhesive to excel in bonding metal, wood, most plastics and masonry products.

It is useful in a majority of bonding situations, and at lower temperatures. , violent changes in temperature, rain, and ultraviolet (UV) radiation. It will wet out and bond to wood fibre, fibreglass, reinforcing fabrics, foam and other composite materials, plus a variety of metals. We could successfully track the time evolution of spatial heterogeneity in the system during the curing reaction and combine the bulk mechanical properties of the resultant resin. In most cases, the builder does not even need a tape measure. West System G/flex is a tough, resilient epoxy engineered for a superior grip to metals, plastics, glass, masonry, fiberglass, and wet and difficult-to bond woods. Cure time at 70 Deg F is approxmately 5 hours. I have talked to 3 West system dealers about the 207 hardener curing to a clear finish verses the 205 being cloudy, 2 dealers have said that there is no difference between the 2 hardeners as far as the finish after they cure, the 207 has a slower cure time. Gives a 46 minute pot life and a long open or working time of 75 minutes at room temperature. Like most brands of epoxies West System have different curing speeds for their hardeners, we currently stock 205 fast and 206 slow hardeners. It's a normal by-product of the curing process and it's easier to spot in cool, moist conditions. 207 Special Clear Hardener is formulated for coating and fiberglass cloth application where a clear, moisture-resistant, result is preferred.
