Patent
CA 2049854
The present invention relates to binder compositions containing A) 10 to 99 parts by weight of a copolymer component containing at least one copolymer prepared from olefinically unsaturated compositions having a weight average molecular weight of 1,500 to 75,000 and having in chemically bound form both (i) 1 to 30% by weight of cyclic carboxylic anhydride groups (calculated as C4H2 0 3) and (ii) 1 to 29% by weight of epoxide groups (calculated as C2H3 0) and B) 1 to 90 parts by weight of a hydroxyl component containing at least one organic polyol having at least two hydroxyl groups per molecule, provided that for every anhydride group of component A) there are 0.1 to 10 hydroxyl groups of component B). The present invention also relates to the use of these binder compositions as binders for heat-curing coating compositions or sealing compositions optionally containing paint auxiliaries and additives.or as binders for room-temperature-curing sealing or coating compositions containing catalysts and, optionally, other paint auxiliaries and additives.
