What kind of resin is west system?
105 Epoxy Resin
105 Epoxy Resin is the base material on which all WEST SYSTEM 105 System epoxy compounds are built. It is a clear, pale yellow, low-viscosity liquid epoxy resin. Blended with hardener at the proper ratio, it cures to a hard, solid plastic with superior physical properties.
How long does it take West System epoxy to harden?
Working Time: 60–70 minutes. Initial cure to solid in thin film: 6–8 hours.
What is the difference between West System 105A and 105B?
The 105A is the quart size. The 105B is the Gallon size and the 105C is the 5 Gallon size. 5 of 5 found this helpful.
What is the ratio for resin and hardener?
Typically, this is 1 : 1 or 2 : 1 between resin and hardener, but there are also much more complicated ones such as 100 : 45. You can usually find the details on the packaging or containers. The mixing ratio has to be very precise, otherwise the epoxy resin will not harden or it will not work optimally.
How thick can I pour West System epoxy?
While it is a slower curing system, it still should not be poured more than ¼” deep at a time. We have found that building up castings ¼” at a time allows the epoxy to cure without overheating.
Can you mix West System hardeners?
Min. Temp. 205 Fast, 206 Slow and 209 Extra Slow Hardeners when mixed with 105 Epoxy Resin work well for wetting out porous surfaces before bonding with thickened epoxy. Other uses include laminating or bonding sheets or layers of materials with tight fitting joints.
Does epoxy resin need a hardener?
On their own, epoxy resins are very stable fluids with relatively long shelf lives. It is only when mixed with an epoxy hardener that they can cure properly. If applied onto a floor without the hardener, the resin would remain a near liquid indefinitely and could not transform into a durable flooring system.
What is epoxy wood?
Epoxy resin is a two-component material, consisting of a resin and a hardener that cures within hours after using it on a wooden surface. It can be cut, ground, and polished for different effects, and its range of options from low to high viscosity make it the best choice for use on wood.
What happens if you put too much hardener in resin?
Adding too much of either resin or hardener will alter the chemical reaction and the mixture will not cure properly.
Can resin be used without hardener?
Polyester resin that is formulated for use with a catalyst will eventually cure or harden without adding the catalyst. The catalyst speeds up the reaction so it cures quicker. ‘Hardener’ is a catalyst.
Can West systems epoxy resin be used on plastic?
When blended at the appropriate mix ratio, WEST SYSTEM Epoxy Resin and Hardeners will cure to a high-strength plastic solid at 72°F. The resulting plastic adheres tenaciously to a wide range of materials including woods, fiberglass and other reinforcing materials, and metals.
What kind of products does West systems sell?
Our dealers carry WEST SYSTEM Epoxy Resin, Hardeners, Fillers, Additives, Reinforcing Materials, Application Tools and Instruction Manuals. Fetching directions…… WEST SYSTEM products are now distributed worldwide and sold through full-service retailers.
Who is winwest system epoxy?
WEST SYSTEM Epoxy was created by Gougeon Brothers–sailors, builders and formulators who know the engineering and the chemistry required for high-performance composite structures. We are an employee-own, family run organization that has maintained our performance-driven development of marine epoxies since the company was founded in 1969.
Why is it important to dispense epoxy resin and hardener correctly?
It is critical that you dispense epoxy resin and hardener at the correct ratio. Altering the amount of hardener does not control cure speed. Instead, it creates an epoxy mixture that can never fully cure and will have greatly reduced physical properties. Epoxy can be accurately metered by volume or weight.
