ABSTRACT:
The adhesive properties of compositions which contain an organic isocyanate, with or without a film-former, are improved by the inclusion of (a) an aliphatic hydrocarbyl nitrite or (b) a nitrite ester of a carbamic acid which acts as an adhesive promoter. The compositions are useful for adhering natural and synthetic polymeric elastomers, and are particularly useful in the production of laminations formed from polyurethane polymers and other substrates including metals, etc. and especially the formation of laminations from the cured tread of a conventional rubber to a curable polyurethane prepolymer composition which can be formed in the shape of a tire body.
