Rigid Casting Foam - All Kit Sizes

  • $35.00


Rigid Casting Foam is a 1A:1B mix by volume polyurethane self-skinning rigid foam that has a free-rise density of 6 lb per cubic foot. Rigid Casting Foam is excellent for casting weapon props as well as functional pieces.

If you need a casting resin for solid pours such as small bones or decorative parts, check out our economical casting resin ArtKast. ArtKast Pourable resin maybe used to "slosh" a hollow skin that can then be back-filled with Rigid Casting foam to create a tough, impact-resistant, light-weight part.

Generally Rigid Casting Foam is poured into TinSil or PlatSil silicone molds or properly released (Pol Ease 2300) 74 & 75 Series polyurethane rubber molds.

Rigid Casting Foam cures Tan but can be pigmented with PolyColors Pigments. (See urethane additives)
