AIR DRYING MODIFIED ALKYD RESIN BINDERS, METHOD FOR THE PRODUCTION THEREOF, COATING AGENTS BASED ON THE MODIFIED ALKYD RESIN BINDERS AND THEIR USE THEREOF AS BUILDING PAINT.

摘要

Air-drying modified alkyd resin binding agents, composed of (a) between 40 and 75 % by weight of dessicant and/or semi-dessicant fatty acids, (b) between 15 and 35 % by weight of di- and/or polyols, at least 80 % by weight of the alcohols being composed of dipentaerythrite and/or ditrimethylolpropane, (c) between 5 and 25 % by weight of polycarboxylic acids or their anhydrides, (d) between 0 and 10 % by weight of di-isocyanates, (e) between 0 and 20 % by weight of monocarboxylic acids and (f) between 2 and 12 % by weight of ethylenically unsaturated monomers, the sum of components (a), (b), (c), (d), (e) and (f) being 100 % by weight. Also, process for the production of some modified alkyd resin binding agents, coating agent based on said binding agents and application of said coating agents, particularly as air-drying building coatings.
