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.
Compat™ 45
Compat™ 45 urethane is a unique urethane rubber which will not inhibit the cure of most Smooth-On platinum or tin cure silicone rubbers. It features a low viscosity for easy mixing and pouring and cures with minimal bubble entrapment. Mix ratio is 1A:1B by volume (85A:100B by weight), pot life is 25 minutes and the rubber cures with an ultimate Shore hardness of Shore 45A. Cured rubber is dimensionally stable (low shrinkage), offers good wear resistance and excellent library life. Compat™ 45 can be used for a variety of applications including making molds to cast silicone prop body parts, animatronic skins and medical trainers, as well as for making rubber masters which can be molded using platinum or tin silicone without inhibition concerns.
Important; Do not use Ecoflex™ Gel, Ecoflex™ 00-10, Ecoflex™ Near Clear, Encapso-K, Rubber Glass™, Solaris™, Soma Foama™ or Sorta-Clear™ 12 or 37 with this product. They are not compatible and inhibition will result.
