Polynt Group 224X
Polynt Group 224X series clear gelcoats are enamel like coatings developed for the composites and fiberglass industry. These gelcoats are used as an enamel coating, similar to paint and are often used as a translucent coating. The 224X series gelcoat can also be used to protect the laminate against u.V. Rays. 224X series gel coats are sag resistant and have a fast curing system. This coating system is ready to spray, requiring only the proper addition of an appropriate methyl ethyl ketone peroxide to cure.Formulated for spray and roll application.Fast gel time and cure time that provide a good cure.Require only the addition of a proper amount of mekp to cure.Resistant to thermal change and weathering for parts in contact with water, severe conditions we recommend an iso/npg base gelcoat for marine applications. Parts that have to be assembled should be sanded and cleaned, to obtain a good adherence.

Isophthalic gel coats are not compatible in the liquid state with ISO/NPG gel coats or ISO/NPG resins. Spray and pumping equipment must be completely clean of these gel coats or resins before isophthalic's 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 recommended methyl ethyl ketone peroxide, to this product without the advice of a representative of Polynt Composites.
