Product Description
PMC™-744
PMC™-744 has been used for years by mold making professionals to cast plaster, concrete, resins, etc. It is excellent for making molds that are strong, durable and dimensionally stable. Low viscosity ensures fine detail reproduction.
Ecoflex™ 00-35 FAST
Ecoflex™ 00-35 FAST is a soft, fast cure platinum-catalyzed silicone that is versatile and easy to use. Parts A and B are mixed 1:1 by weight or volume, pot life is about 2.5 minutes and rubber cures in about 5 minutes at room temperature with negligible shrinkage. Low viscosity ensures easy mixing and pouring. Rubber cures without "tacky" surface, is very soft, very strong and very "stretchy, stretching many times its original size. EcoFlex™ 00-35 FAST is off-white translucent and can be color pigmented using Silc Pig™ silicone color pigments.
