Duratec Clear Hi-Gloss Gel Coat Additive
Improve Gloss and Get an Open-Air Cure
Duratec® Clear High Gloss Additive can be mixed in a 1:1 ratio with regular gel coat to reduce viscosity and porosity, improve gloss level, and permit a complete open-air cure. It can also be blended with a 15% ratio to tooling gel coats to upgrade mold surfaces, improve gloss retention, increase impact resistance, and reduce heat distortion.
The reduction in viscosity allows gel coats to be sprayed controllably through siphon and HVLP equipment, reducing sanding and polishing time. When used for repairs, this product will result in a low porosity surface.
PLEASE NOTE: When making below-the-waterline repairs on boats, we recommend adding our #71 Styrene Wax to maximize hardness.
Requires 2% MEKP.
When added to gelcoat it does let the mixture cure while exsposed to air.
One unantisipated result however is that the product when used in a 50% mix with the gelcoat is that it dilutes the color of a premixed gelcoat making the color lighter after curing. So if your like I am an not a color nixing guy you may want to start with a shade or 2 darker gelcoat on the fan deck.
Another effect of the "thinning" of the gelcoat is that the color if light in shade will not cover the substrate if it is dark in color. To help with this aspect I used white pigment in the resin mixtures in the layup, and it helped considerably.
Otherwise it mixes well with the gelcoat and pours like 40 wieght oil out of the can, even has the same shade.
