PolyFoam R-2 is a two-part, rigid polyurethane casting foam. This self-skinning foam has a free-rise density of 2 lb/ft³, but should be cast at a density of 4 to 8 lb/ft³ to achieve good surface detail and mold fill. Generally, PolyFoam products should be cast in TinSil® or PlatSil® silicone molds. Barrier coats (e.g., a fast-drying primer paint) can be applied to silicone molds before casting foam in order to produce pre-primed parts right out of the mold. These foams can also be poured into Poly 74 & 75-Series polyurethane rubber molds that have been coated with PolyCoat Sealer & Release Agent.

Mix Ratio: 1A/1B 
Mix Viscosity: 500 cP

Since these products are self-skinning, cast parts will capture full surface detail of the mold used. PolyFoam systems find numerous uses in commercial, industrial, hobby, craft, prop and display applications.
