Patent

CA 1337890

The invention relates to oxidatively cross-linkable, water dilutable binders which consist essentially of a modified co-polymer of olefinically unsaturated compounds, having a molecular weight range of from 6000 to 160,000 as determined by gel permeation chromatography, and having a) for each 100 g of solids content, a total of from 60 to 250 milliequivalents of chemically incorporated carboxyl groups, of which from 10 to 100% are neutralized thereby rendering the product dilutable in water and b) from 15 to 50% by weight of chemically incorporated moieties corresponding to the formula -O-R wherein R represents an olefinically monounsaturated or polyunsaturated aliphatic hydrocarbon having a molecular weight above 166 and containing from 12 to 22 carbon atoms. The binders are suitable for lacquers, coating compositions and sealing compounds. They have improved storage stability.
