Abstract: The invention relates to heat-curing sealant compositions including at least epoxy resin, dicyandiamide or an amine complex of a Lewis acid, polyurethane polymer (PUP) comprising isocyanate groups and polyaldimine. Said one-component sealant compositions are characterized by fast skin formation and high tensile strength. Due to short skin formation time, said compositions are optimally suitable for use as sealants in autobody work because a CDP paint can be excellently layered on top of same.

Abstract: The present invention relates to a method of producing an edging-fold bond. For this purpose use is made more particularly of high-viscosity adhesives. The method features reduced bubble formation within the edging fold and also within the sealant (where present) that seals the edging-fold seam. More particularly the adhesive comprises spacers which further reinforce this effect.

Abstract: An impact modifier with epoxy group termination is described, comprising the reaction product of a) two or more polyols, b) one or more polyisocyanates and c) at least one epoxy resin comprising an epoxy compound containing a primary or secondary hydroxyl group, wherein the polyols comprise a1) at least one polyether polyol and a2) at least one OH-terminated rubber, where the weight ratio of polyether polyol to OH-terminated rubber is in the range from 7:3 to 2:8, as are an isocyanate-terminated prepolymer as a possible intermediate and processes for preparation thereof. The products obtained are suitable for improving the impact resistance of epoxy resin compositions, especially of 1K or 2K epoxy resin adhesives.

Abstract: A method is described for producing liquid rubber containing an impact-resistance modifier terminated by an epoxy group, the method comprising the reaction of an isocyanate-terminated prepolymer with an epoxy resin, which comprises an epoxy compound including a primary or secondary hydroxyl group, in the presence of a compound selected from anhydrides, ketones and aldehydes as glycol scavengers. The isocyanate-terminated prepolymer, the epoxy resin and the glycol scavenger are mixed with one another, or the epoxy resin is reacted with the glycol scavenger, before they are mixed with the isocyanate-terminated prepolymer. Gelling in the reaction mixture is avoided by the method. The obtained products are suitable for improving the impact resistance of epoxy resin compositions, particularly one-component or two-component epoxy resin adhesives.
