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.
TASK™ 9
TASK™ 9 Colormatch is a high performance urethane casting resin that features very high compressive strength and tensile strength. TASK™ 9 is clear amber, which makes this plastic very easy to color using SO-Strong™ or IGNITE™ colorants. With a mix ratio of 1A:1B by volume, TASK™ 9 is easy to use and a low mixed viscosity (300 cps) ensures minimal bubble entrapment. Pot life is 7 minutes and cure time is about 60 minutes (depending on mass).
