Abstract
Compositions comprising at least one isocyanate-functional organosilane, preferably in combination with at least one polyisocyanate, and, optimally, at least one aromatic nitroso compound having been found to be unexpectedly effective as storage-stable, single-package, one-coat adhesive systems for bonding a variety of elastomeric materials to themselves and other solid substrates, such as metal, fabric, ceramic, and the like substrates. The use of aromatic nitroso compounds is necessary with certain isocyanatosilanes and optional with others, but, in all cases, affords improved performance, especially with respect to environmental resistance.
