Product Description
Ecoflex™ 00-20
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 is skin safe and certified by an independent laboratory.
Free Form™ AIR
Free Form™AIR is an extremely lightweight epoxy putty suitable for an infinite variety of industrial and art-related applications. This is a low-odor, low shrinkage putty that is unique, inexpensive and easy to use. Free Form™AIR is mixed by hand with a 1A:1B by volume or weight mix ratio. It offers a long working time and cures overnight at room temperature to a hard, rigid epoxy that is very strong. Cured Free Form™AIR is so lightweight, it will float in water. It can be sanded, shaped, and drilled. It will readily accept any paint. Free Form can also be color pigmented with UVO™ or Ignite™ colorants.
