Polyurethane Foam | 2-Part Expanding Resin

Polyurethane Foam is a convenient two-part resin system designed for modelers who need a lightweight, rigid material that expands after mixing. When the two parts are combined, the resin expands to approximately 30 to 40 times its original volume, making it useful for creating filled forms, shapes, scenery features, and other modeling applications where controlled expansion is desired. The material sets quickly into a rigid plastic foam, allowing hobbyists to move efficiently from mixing to shaping and finishing. This two-part system comes with instructions to help guide the mixing and application process. Because the resin expands significantly, careful preparation and appropriate workspace planning are important when using Polyurethane Foam. The expansion makes a small amount of mixed material capable of filling a considerably larger space, which can be useful for model railroad scenery, hobby projects, and custom construction work. The package includes two 8 oz. bottles, providing the two components required for the resin system. Mix the two parts according to the included instructions and allow the material to expand and set as directed. Once cured, Polyurethane Foam forms a rigid plastic foam that can become a useful foundation for additional modeling and finishing work.
