Adhesive compositions effective for bonding runner to metal and containing no more than about 1000 ppm of lead especially adapted to bond vulcanized elastomers to rigid substrates, like metal are disclosed. The adhesives are useful in combination with primer coats, and as one-coat adhesives and provide durable, rubber tearing primary adhesive bonds after exposure to harsh conditions. The adhesives exhibit excellent bond versatility, sweep resistance, and in-can storage stability. In one embodiment, the adhesive compositions of the present invention consist essentially of less than 1000 ppm of lead, at least one diluent as water or organic solvent, a halogen-containing film former, optionally a nitroso compound, brominated dichlorobutadiene, and/or adhesion promoter, and an acid scavenger comprising zinc phosphate.
An adhesive composition containing less than 1000 ppm of lead, and comprising
The adhesive composition according to claim lwherein (b) is chlorinated natural rubber (c) is an aromatic nitroso compound and further comprising a second halogen-containing polyolefin which is brominated polydichlorobutadiene, and (e) a maleimide compound.
