Description GTP Elastomer 30 is a versatile, two component liquid castable polyurethane elastomer. GTP Elastomer 30 combines high strength and elongation with excellent chemical resistance to create durable flexible molds or parts that have low residual surface tack. GTP Elastomer 30 is insensitive to typical environmental moisture, has low viscosity, high strength and low durometer. Some features include good grease and oil resistance, good flow into fine detail, good dimensional stability and good adhesion between pours. It is tough, with high tear strength and is insensitive to inhibition.

Storage Shelf Life
Packaging GTP Elastomer 30 is shipped from the factory in sealed containers. The containers should be stored in a cool dry area that is protected from direct sunlight and moisture. Storage temperatures should not exceed 80° F. The shelf life of factory sealed containers stored under these conditions is six months. Containers that have been opened should be resealed immediately after material has been removed in order to prevent solvent evaporation. GTP Elastomer 30 is available in convenient 2-quart, 2-gallon, 10-gallon, 60-gallon and 100-gallon kits. GTP Elastomer 30 has a non-hazardous rating for shipping.
