  • Storage-stable, moisture-curing polyurethane adhesive with rapid adhesive formation on glass
    Patent number: 10494552
    Abstract: A moisture-curing adhesive composition has a) at least one polyurethane polymer having isocyanate groups, b) at least a silane adhesion promoter, c) at least one amine catalyst, and d) at least one chelate complexing agent. Compositions are suitable especially as adhesive or sealant, in particular for glass panes, for example in vehicle construction or vehicle repair, wherein the use of a primer or activator can be dispensed with.
    Type: Grant
    Filed: September 22, 2015
    Date of Patent: December 3, 2019
    Assignee: SIKA TECHNOLOGY AG
    Inventors: Alain Zahn, Michael Schlumpf, Urs Burckhardt

  • Two-stage curable composition containing a surface-deactivated polyisocyanate
    Patent number: 8759455
    Abstract: Single-component compositions are disclosed, which can be cured in two stages, wherein in the first curing stage, compositions pre-cured by means of moisture and having in particular plastic properties are formed, and wherein in the second curing stage, compositions cured by means of heat and having in particular elastic properties are formed. The two-stage compositions are suitable in particular as adhesives and have the great advantage that thanks to said two-stage compositions, an adhesive can be applied to a substrate, said adhesive cures by means of moisture in such a way that it can be handled and stored without problems, and said adhesive can be cured easily in an adhering step by means of heat only when needed.
