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.

Mold Max™ 15T

Mold Max™ 15T silicone is a water white translucent tin cured silicone rubber compound that has exceptional tear strength and working properties. It features Smooth-On’s “Libra™” catalyst for long library life. Mixed 100A:10B by weight, vacuum degassing is recommended for de-airing. Rubber cures overnight at room temperature. Mold Max™ ‘T’ silicones can be thickened with Thi-Vex™ thickener for brush-on application and effects.
