Patent
CA 2266211
The present invention relates to compounds which are substantially free from isocyanate groups, have an alkoxysilane group content (calculated as Si, MW 28) of 1 to 6% by weight, based on the weight of the compounds, and containing sufficient chemically incorporated hydrophilic groups to form a stable dispersion with water, wherein the alkoxysilane groups are incorporated as the reaction products of a) a polyisocyanate component having a minimum average functionality of 2.4 and containing at least 50 % by weight of polyisocyanate adducts and b) compounds containing secondary amino groups and alkoxysilane groups. The present invention also relates to the use of these compounds for the preparation of coatings, sealants and adhesives.
