EXPOXY HARDENERS 3:1 RATIO

West System 207 Special Coating Hardener
This hardener was especially developed for use
with WEST SYSTEM Brand 105 Resin in coating applications where an
exceptionally clear, moisture-resistant, natural wood
fi nish is desired. Cures to a light amber colour, similar to traditional
spar varnishes. An ultraviolet inhibiting
additive improves the resistance of a WEST SYSTEM 105/207 mixture to
sunlight, but the cured epoxy surface will still
require the additional protection of a quality UV-filtering varnish. 207 is
designed to self level for smooth finishes,
and to wet-out and bond fabrics. Although it provides good physical properties
for general bonding applications, it is
more diffi cult to thicken and less cost effective for this purpose than 205 or 206
Hardeners. It's also used for
laminating veneers where bleed through at joints may be exposed to sunlight.
