Product Description

West System 207 Special Coating Hardener for R105 Epoxy Resin has been specifically developed for coating applications where an exceptionally clear, moisture resistant, natural wood finish is desired.  An ultraviolet inhibiting additive improves resistance of a West System 105 / 207 mixture to sunlight, however, the cured epoxy surface will still require further UV protection with a quality UV filtered varnish or two pack polyurethane paint.  It has been designed to work well in humid conditions.

As a base for an adhesive mix, 105 / 207 is more difficult to thicken, and less cost effective for the purpose than 205 Fast or 206 Slow hardeners.

Mix Ratio: 1 Part hardener (H207 or H209) to 3 parts resin by volume / 3.5 parts resin by weight.
