Abstract: The present invention provides a honeymoon adhesive comprising a first and a second part which are separate from one another, wherein the honeymoon adhesive comprises at least three components selected from the group of an amount of a silylated functionalized polymer, an amount of a catalyst and an amount of water. The first part contains maximum two of the first and second parts. The second part contains at least the third component, with the proviso that neither the first nor the second part contains all three components. The present invention further provides a system employing the adhesive, an article employing the adhesive, and a method of adhering surfaces together using the honeymoon adhesive.

Abstract: A bitumen-free liquid prepolymer composition comprising:a) from 50 to 99% by weight of an isocyanate-containing prepolymer obtained by the reaction of a stoichiometric excess of diphenylmethane diisocyanate with an organic compound containing a plurality of isocyanate-reactive groups, andb) from 50 to 1% by weight of a substituted diphenylmethane compound which is free from ester groups, isocyanate groups and isocyanate-reactive groups and has a melting point below 25.degree. C., a boiling point above 150.degree. C. and a fire point above 100.degree. C.The composition has a good stability and is useful for preparing elastomers and foams.
