West System Epoxy 207B Special Clear Hardener Only 1.45kg

West System 207 Special Coating Hardener is formulated for use with West System 105 Resin for coating applications where an extremely clear finish is desired, especially when working in humid conditions. This hardener also provides excellent adhesion for bonding applications although 207 is not as cost ~effective as 205 or 206 Hardeners. 207 contains an ultraviolet inhibiting additive which improves the resistance of a West System 105 207 mix to sunlight. However, the cured epoxy surface still requires long ~term UV protection with a quality marine paint or a UV filtered varnish.
