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.

EpoxAcoat™ HT

EpoxAcoat™ HT is a slightly thixotropic epoxy gel coat that offers high heat resistance (post cure required).  Cured epoxy is tough and offers exceptional abrasion resistance.  This surface coat will wet out well over a variety of surfaces with good sag resistance.  Applications include laminating, precision tooling, master and pattern making, core boxes and fixtures.
Use as a surface coat for EpoxAmite™ HT high temperature laminating epoxy.
