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.
SORTA-Clear™ 40
SORTA-Clear™ Series rubbers are premium water clear translucent silicone rubbers (platinum catalyst) which cure at room temperature with negligible shrinkage. This product requires a gram scale for measuring parts A + B. SORTA-Clear™ 40 comes in Shore 40A hardness and features high tensile and tear strength.
SORTA-Clear™ silicones are ideal for making prototype, jewelry or other molds of any configuration where model visibility is important (i.e. extracting a model from the mold via cutting). Materials such as urethane, epoxy or polyester resins can then be cast into SORTA-Clear™ silicone without application of a release agent. Other materials such as wax and low melt metal alloys can also be cast into SORTA-Clear™. SORTA-Clear™ can be pigmented with SILC Pig™ silicone pigments.
SORTA Clear™ 40 silicone rubber is FOOD SAFE and can be used for culinary applications including casting chocolate and other confections.
Certified Skin Safe - Cured SORTA Clear™ 40 is skin safe and certified by an independent laboratory.
