Storage-stable, heat-reactive aqueous compositions comprising at least one novolak phenolic resin, at least one formaldehyde polymer, and water, wherein said formaldehyde polymer is present in an amount sufficient to crosslink said novolak resin, are useful for direct bonding of natural and synthetic resins to rigid and non-rigid substrates and as primers for rubber-to-metal adhesives. The herein-described aqueous adhesive systems can have incorporated therein conventional additives such as fillers and the like.

Aqueous compositions comprising phenolic resin and crosslinking agent

Compositions comprising at least one halogen-containing polymer, at least one aromatic nitroso compound, at least one salt of certain inorganic and organic acids, and, optionally, at least one maleimide compound, have been found to be unexpectedly effective as storage-stable, single-package, one-coat adhesive systems for bonding a variety of elastomeric materials, including vulcanizable and vulcanized natural and synthetic elastomer compositions, to themselves and other structural substrates.
