West 207 Clear Hardener

Description

West System® 207 Special Clear Hardener has been specially developed for coating applications where an exceptionally clear, moisture resistant, natural wood finish is desired. 105/207 mixtures resist clouding in humid conditions and exhibit extremely low blush formation – as low as any epoxy, including so-called “no-blush” epoxies.

Thin film applications roll out and tip off smoothly, requiring less sanding in preparation for finishing coatings. 105/207 has strong physical properties, so it can be used as a structural adhesive for gluing and laminating. It has excellent compatibility with paints and provides a beautiful, long lasting finish when used with quality UV-filtering polyurethane varnish. 105/207 cures to a very light amber colour.

Please Note: 207 Special Clear Hardener should not be used below 16°C unless you elevate the working temperature to allow the system to cure properly. For best results, postpone coating until the temperature in the working environment is about 21°C.

Mix ratio: 3 parts resin : 1 part hardener
