Crystic® Polyester Resin 489
Crystic® Polyester Resin 489 is a thixotropic isophthalic polyester resin. When used with Crystic Gelcoat 65PA, they produce a matched performance system for molding boat hulls with outstanding durability and superior blister resistance. The outstanding wetting characteristics of Crystic 489 provide rapid impregnation with freedom from drainage.
