Product Description
Rebound™ 25
Rebound™ 25 is an easy-to-use platinum-cure silicone rubber which self-thickens for making brush-on molds of almost any model. Mixed 1A:1B by volume (no scale necessary), Rebound™ rubber can be applied with a brush or spatula to vertical surfaces without sagging and will cure with negligible shrinkage to a flexible rubber.
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.
