Blush-free 207 Special Clear Hardener was developed for
coating and fiberglass cloth application where an exceptionally clear,
moisture-resistant, natural wood finish is desired. Blended with 105 Epoxy
Resin, 207 Hardener will not blush or turn cloudy in humid conditions. Thin
film applications roll out and tip off smoothly, requiring less sanding in
preparation for finish coatings.
Professional and first-time builders like 207 Special Clear
Hardener because it is reliable, easy to use, as does not blush. Three coats or
more can be applied in one day without additional surface preparation. Fewer
coats are required to fill fiberglass weave and in most cases, the final
coating can be sanded the following day. Boats can be built faster. Builders
also appreciate the excellent fiberglass wet-out characteristics achieved with
105 Resin/207 Special Clear Hardener, yet it won’t drain from vertical surfaces
like the very slow curing, low-viscosity epoxies.
105/207 Epoxy has strong physical properties, so it can be
used as a structural adhesive for gluing and laminating. It has excellent
compatibility with paints and varnishes. An ultraviolet inhibitor in 207
Special Clear Hardener helps provide a beautiful, long-lasting finish when used
with quality UV filtering varnish. 105/207 cures clear and colorless.
