Patent number: 4778845Abstract: A one-component adhesive and/or sealing mass which is stable and pumpable at temperatures up to 30.degree. C. containsat least one prepolymer on the basis of a polyurethane, which contains from 0.1 to 15 percent by weight, referred to the prepolymer, of free, reactive isocyanate groups, andat least one with heat activatable hardener.Thereby the stoichiometric ratio between said prepolymer and said hardener is chosen in such a way that only a partial cross-linkage is possible during heating said mass to temperatures from 60.degree. C. to 180.degree. C., and that a product is obtained having from high viscous to plastic characteristics.The inventive masses may be used for bonding and/or sealing of one or more materials of the same or different origin to a composite.Type: GrantFiled: June 4, 1987Date of Patent: October 18, 1988Assignee: Sika AG, vorm.
