The present invention is directed to a pressurized can containing a polymer foam composition for use in one component and two component foams, said polymer foam composition comprising an unsaturated resin and an oligomeric acrylic resin, characterized in that the composition has a cure rate of maximum 3 hours.
Description
field of invention [0001] The present invention relates to sprayable polyurethane foams, and more particularly to acrylate-terminated urethane and polyester oligomer foams in aerosol cans and / or pressure vessels. Background of the invention [0002] Pressurized fluids stored in reservoirs (tanks or containers) are used in a wide variety of applications. Sprayable foams are used in several industrial applications as well as by hobbyists. One well-known example of a sprayable foam is polyurethane foam. Among other applications, polyurethane is used in highly resilient flexible foam seating, rigid foam insulation panels, microcellular sprayable foam seals and gaskets, durable elastic rubber wheels and tires, electrical potting compounds, Spandex fibers, carpet underlayment pads, hard plastic parts. [0003] Currently available sprayable foam formulations in aerosol cans and / or pressure containers are one-component and two-component PU foams (OCF=one-component foam; TCF=two-c...
