Title: USE OF VINYL ACTETATE-COPOLYMERS AS A SHRINKAGE-REDUCING ADDITIVE IN COLD-CURING SYSTEMS
Abstract:
The invention relates to the use of vinyl acetate-copolymers as a shrinkage-reducing additive (low profile additive) in cold-curing systems for producing composite materials, characterized in that vinyl acetate-copolyerisate of 40 to 95 wt% vinyl acetate and 5 to 60 wt% of one or more co-monomers from the group containing vinyl esters of unbranched or branched carboxylic acids having 3 to 20 C-atoms and methacrylic acid esters and acrylic acid esters of unbranched or branched alcohols having 2 to 15 C-atoms are used, wherein the specifications in wt% relate to the total weight of the co-monomers and add up to 100 wt%.
