Last-A-Foam
Last-A-Foam is a rigid, CFC-free, polyether polyurethane foam with fine closed-cell structure and is wonderfully versatile for sandwich-core applications. It cuts and shapes easily with common woodworking tools and bonds to itself and other materials with most epoxy, polyester, or urethane-type adhesives. Last-A-Foam will not absorb liquid water, and it is largely unaffected by solvents and paints. It can be used in regular molds after gel-coat and first two layers of glass are laid in. Last-A-Foam is specially formulated to meet the physical-property demands of the FRP-composite boat builder.
