205 FAST HARDENER
205 Fast Hardener is formulated for general coating and bonding applications at lower temperatures and to produce a rapid cure that develops its physical properties quickly at room temperature. 105/205 forms a high-strength, moisture-resistant solid bond with excellent bonding and barrier coating properties. Not intended for clear coating.
206 SLOW HARDENER
206 Slow Hardener is a low-viscosity epoxy curing agent for use when extended working time or a longer cure time is needed. It also provides adequate working time at higher shop temperatures. When combined with 105 Resin in a five-part epoxy resin to one-part hardener ratio, the cured resin/206 Slow Hardener mixture yields a rigid, high-strength, moisture-resistant solid bond with excellent bonding and barrier coating properties. 206 Slow Hardener is not intended for clear coating.
207 SPECIAL CLEAR HARDENER
207 Special Clear Hardener was developed for coating and fiberglass cloth application where an exceptionally clear, moisture-resistant, carbon fiber or natural wood finish is desired. 207 Hardener will not blush or turn cloudy in humid conditions. Thin film applications roll out and tip off smoothly, requiring less sanding in preparation for finish coatings.
209 EXTRA SLOW HARDENER
209 Extra Slow Hardener is formulated for use with WEST SYSTEM 105 Resin or general coating and bonding applications in extremely warm and/or humid conditions or when extended working time is desired at room temperature. Provides approximately twice the working time of 206 Slow Hardener. 105/209 forms a high-strength, moisture-resistant solid with excellent bonding and coating properties. Not intended for clear coating.
