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.
