Polytek PolyFoam F-3 Polyurethane Casting Foam
PolyFoam F-3 is a two-part, flexible polyurethane casting foam. This self-skinning foam has a free-rise density of 3 lb/ft³, but should be cast at a density of 5 to 8 lb/ft³ to achieve good surface detail and mold fill. PolyFoams are useful for creating props, tools and any decorative, functional or artistic object which needs to be flexible and lightweight. These flexible foams should be cast into PlatSil® or TinSil® silicone rubber molds, but can be cast into polyurethane rubber molds that have been coated with PolyCoat Sealer & Release Agent.
Mix Ratio: 1A/2B by weight
Mix Viscosity: 2000 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.
