Foam Resin for Lightweight, Highly Detailed Flexible Castings
Highly recommended for making foam rock castings
Formula X7 Casting Foam makes lightweight, flexible castings for a variety of art, model making, and industrial applications. It’s strong, bendable, tear-resistant, and self-skinning, which means the cured foam forms a continuous, high-density skin that can be painted and weathered. Natural color is white, but vibrant colors can be achieved by adding color pigments. Mix ratio is a convenient 1 part A to 2 parts B by volume. Pot life is 60 seconds; de-mold in 2 hours. Expands to approx. 3.5 times its original volume. Each pound of mixed material makes 100 cu in. of foam.
Note: This product requires a special release agent - #86627 Ease Release® 2831 - available separately. Use of any other release agent will cause Flex Foam castings to collapse.
