West System 105A Epoxy (1.0kg) Resin only

West System 105 Epoxy Resin (1 litre tin) is the base material on which all West System family compounds are built. 105 is a clear, pale yellow, low-viscosity liquid epoxy resin that, when combined with any of the West System Hardeners, will cure to a hard, solid plastic that is functionally waterproof and highly resistant to moisture vapour. Based on which hardener you choose, 105 will cure at a wide range of temperatures.

The epoxy resin will wet out and bond with wood fibre and fibreglass. It will also bond well with a variety of metals. Unlike polyester or vinylester resins, West System epoxy does not shrink after curing. It's also much safer to use than styrenated resins as it has a relatively high flash point and no solvent odour.

Thickening:

When used with West System fillers, the resin creates an excellent structural adhesive or fairing compound. Epoxy thickened with adhesive (high-density) fillers makes structural bonds, bridges gaps and also fills voids. When thickened with fairing (low-density fillers), the epoxy is easily sanded and shaped after it cures.

Coating:

105 is also a superb coating material. When applied with a roller, the resin offers excellent thin-film characteristics and will flow out and self-level without fisheying.

Please note you will need the 205 fast harder to cure this product, available separately mixing ratio is 5:1 resin to hardener.
