Abstract

Aqueous bonding agents based on at least one phenolic resin, at least one aromatic dinitroso compound and a polyvinyl alcohol are suitable as a one-coat aqueous rubber-metal bonding agent to achieve permanent rubber-metal bonds. These bonding agents can be substantially free from organic solvents and halogen compounds, and allow one-coat application without an additional, previous application of a primer.
