Ecoflex Rubbers are mixed 1A:1B by weight or volume and cure at room temperature with negligible shrinkage. Rubber also cures without a "tacky" surface. Low viscosity ensures easy mixing and de-airing, or you can choose to mix and 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. Ecoflex Rubbers are water white translucent and can be color pigmented with Silc-Pig pigments for creating a variety of color effects.
