207 Special Coatings Special Hardener
207 Special Coatings Special Hardener has been formulated for use with West System 105 Resin for coatings requiring an extremely clear finish. This hardener also provides excellent adhesion for bonding applications. The 207 contains a UV inhibitor to protect the 105/207 blend from sunlight. However, the cured epoxy surface still requires long-term UV protection using a marine paint or a two-component UV-filtering clearcoat.
