Product Description
Ecoflex™ 5
Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage. Low viscosity ensures easy mixing and de-airing. Dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very “stretchy”, stretching many times its original size without tearing and will rebound to its original form without distortion.
SORTA-Clear™ 12
SORTA-Clear™ 12 is a premium water clear translucent silicone rubber (platinum catalyst) which cures at room temperature with negligible shrinkage. SORTA-Clear™ 12 cures in 12 hours with a final Shore hardness of 12A. SORTA-Clear™ 12 features exceptional tear and tensile strength.
SORTA-Clear™ silicone is 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™ pigments.
