WEST SYSTEM Epoxy Kit A-1 Fast is a two-part epoxy system comprising 105 Epoxy Resin and 205 Fast Hardener. It is intended for general bonding and coating tasks where a relatively rapid cure is required.

When mixed at the specified 5:1 resin-to-hardener ratio by volume, the 105/205 system produces a high-strength, rigid and moisture-resistant cured epoxy with bonding and barrier-coating properties. The low-viscosity resin is designed to wet out wood fibres, fibreglass and reinforcing fabrics, and may also be used with suitable WEST SYSTEM fillers for gap filling and fairing applications.
