Formulated to apply through
plural component spray equipment onto ambient temperature molds when large volumes
of in-mold primer are required; this is simply a more reactive version of Duratec
Polyester Surfacing Primer.
Usage For
post-painted parts; an in-mold gel coat replacement for polyester, vinyl ester
and most epoxy composite parts.
Features Low
subsurface porosity reduces time and labor when preparing topcoat. Here's
why you should choose Duratec Polyester Fast Cure Surfacing Primer-- Rapid
gel time—time saving generates faster mold cycling times. Easy
sanding—rapid sanding versus gel coats reduces the time to topcoat. High
elongation—improved impact resistance versus gel coats.
High HDT—a
201°F,
94°C heat
distortion temperature reduces pattern print-through during
the post painting process.
Note:
Should an even higher HDT (to
300°F,
150°C)
be necessary, use Duratec Vinyl Ester Primer.
