UltraShield high-performance gelcoat utilizes the same dispersion vehicle as Ultra Plus-NPG/ISO gelcoat, an isophthalic, acid-based unsaturated polyester resin, but with higher- performance pigments and additives, yielding 100 to 217 percent increases in gloss and color retention. After 1000 hours in Xenon arc weatherometer tests, UltraShield high-performance gelcoat retains 80 to 95 percent of its original gloss-compared with 30 to 40 percent for conventional gelcoat-while demonstrating superior color retention, including greater resistance to yellowing.
