Extended Working Time Epoxy Hardener for West System 105 Resin
West System 206 Slow Hardener (21204722) is a premium epoxy curing agent designed to provide extended working time when used with West System 105 Epoxy Resin. Formulated for structural bonding, coating and composite laminating applications, 206 Slow Hardener allows more time for positioning, fibre wet-out and complex lay-ups before initial set. This makes it ideal for larger laminations, warmer climates and detailed marine or woodworking projects where precision is critical. When mixed at the recommended ratio with 105 Resin, it produces a high-strength, moisture-resistant epoxy system with excellent durability. Compared to fast cure hardeners, 206 Slow Hardener reduces exotherm in larger batches and supports improved laminate consolidation. Widely trusted in Australian boat building, timber construction and composite fabrication industries, it delivers dependable structural performance with greater application flexibility.
