Product Description
Mold Star™ 16 FAST
Mold Star™ rubbers are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star™ silicones feature relatively low viscosities and vacuum degassing is not required for most applications. Mold Star™ 16 FAST is a fast material with a 6 minute pot life and 30 minute cure time.
Ecoflex™ 00-20 FAST
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. 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.
Certified Skin Safe - Cured Ecoflex™ 00-20 FAST is skin safe and certified by an independent laboratory.
