ISO/NPG gel coats are not compatible in the liquid state with Isophthalic gel coats or Isophthalic resins. Spray and pumping equipment must be completely clean of these gel coats or resins before ISO/NPG can be used. Do not over-mix gel coats. Over-mixing breaks down gel coat viscosity, increasing tendencies to sag, and causes styrene loss, which could contribute to porosity. Gel coats should be mixed once a day for 10 minutes. The gel coat should be mixing to the sides and bottom of the container with the least amount of turbulence possible. Air bubbling should not be used for mixing. It is not effective and only serves as a potential for water or oil contamination. Do not add any material, other than a recommend methyl ethyl ketone peroxide, to this product without the advice of a representative of Polynt Composites.
- HIGHLIGHTS
Very good resistance to yellowing and fading due to sun exposure; Resist to thermal change and weathering; May be used in submerged application; Chalking resistant; Easy to sand and polish
- Handling
Uncatalyzed, standard cure gel coats have a usage life of 90 days from date of manufacture when stored at 73°F or below, in a closed, factory sealed, opaque container, and out of direct sunlight. Fast Cure gel coats are stable for 30 days. The usage life is cut in half for every 20°F over 73°F.
