摘要： Solid, non-melting polyurethanes having a glass transition temperature of at least 40° C. and free isocyanate groups are self-bonding materials that are useful in a variety of adhesive and molding operations. Under conditions of heat and moisture, these polyurethanes will self-bond. The polyurethanes can be used as adhesive coatings, which are solid and non-tacky and thus can be transported and stored easily under ambient conditions. These polyurethane adhesives 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.

摘要： Coated proppant particles are prepared by coating the particles with at least one polyisocyanate, and at least one urethane catalyst, and starch is present during at least part of the curing step. The starch becomes incorporated into in at least a portion of the cured coating. The coating cures rapidly at moderate temperatures, and bonds to itself well under conditions of heat and pressure as are experienced by the particles in subterranean formations.
