  • Solid, self-bondable organic polymers and methods for using same
    Patent number: 10160892
    Abstract: Solid compositions made from or coated with a non-melting organic polymer having a main glass transition temperature of at least 65° C., few if any isocyanate groups and a wet aged glass transition temperature of up to 60° C. are self-bonding materials that are useful in a variety of adhesive and molding operations. Under conditions of heat and moisture, these compositions will self-bond. The compositions can be used as adhesive coatings, which are solid and non-tacky and thus can be transported and stored easily under ambient conditions. These compositions are especially useful in applications in which, due to the location and/or orientation of the substrates, liquid or melting materials cannot be applied easily or will run off the substrates.
