Two Component West System Epoxy System

The Two Component West System Epoxy System contains the West System 105-A Epoxy Resin and the West System 206-A Hardener, both formulated to be used together for composite construction and repairs.

105-A Epoxy Resin is a clear, pale yellow, low-viscosity liquid resin, used for composite construction and repairs that require high-strength, moisture-resistant coating, bonding and filling. When mixed at the proper ratio with the West System 206 Slow Hardener, it is designed specifically to wet out and bond with many materials, such as wood fiber, fiberglass, reinforcing fabrics, aluminium, steel and ferro-cement. 105 Epoxy Resin is formulated without volatile solvents and does not shrink after curing. Moreover, it has a relatively high flash point and no strong solvent odour. This makes it safer to work with than either polyester or vinylester resins.

This Epoxy Resin is an excellent adhesive with many applications. It is used to bridge gaps and fill voids which, when cured, can be sanded and shaped.

206-A Slow Hardener is a low-viscosity epoxy curing agent. It is used when extended working and cure time is needed or to provide adequate working time at higher temperatures. When combined with 105 Epoxy Resin in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties.

Storage and Shelf life

With proper storage, West System 105 Epoxy Resin and hardeners should remain usable for many years, especially if the containers are kept closed in order to prevent contamination. Over time, the resin will thicken slightly which, in turn, will require extra care when mixing.

Both resin and hardeners should be stored at room temperature. Indeed, if the resin freezes and thaws out many times it can cause crystallization. If this happens, however, it is a simple matter to dissolve the crystals by warming the resin to 50°C and stirring for a while.
