Product Description
Matrix Dryve™
Matrix Dryve™ is a versatile all-powder polymer modified gypsum system that has superior physical and performance properties compared to regular gypsum products. It is an “all-powder” alternative to our original Matrix™ NEO powder/liquid system.
EZ-Mix™ 40
EZ~MIX™ 40 is a brushable polyurethane rubber mold compound that mixes and applies easily. Two liquids (Part A and Part B) are measured and combined in equal amounts by volume (no scale is necessary). After a few minutes of mixing, EZ~MIX™ 40 is ready to be applied to a vertical surface with a brush. After a suitable thickness is attained (multiple layers), EZ~MIX™ 40 cures overnight with negligible shrinkage to a flexible, durable mold rubber. Following the application of a support shell, a rubber mold made with EZ~MIX™ 40 is suitable for casting a variety of materials including wax, gypsum, urethane/epoxy resins, concrete, cement, etc.
