Abstract

A resin, suitable for use in coating compositions comprises the reaction product of (1) 40-90% by wt. of an aliphatic monocarboxylic fatty acid ester of a polyhydric alcohol wherein the alcohol portion has at least two free OH groups, (2) 5-40% by wt. of an organosiloxane having at least one free OH or C1-C6 alkoxy group or having both free OH and alkoxy groups, and (3) 5-40% by wt. of an organic polyisocyanate. (3) serves to bond the organosiloxane to the alcohol portion of the ester. The monocarboxylic acid ester may be prepared by reacting an aliphatic, saturated or unsaturated monocarboxylic acid or anhydride with a polyhydric alcohol having at least 3 free OH groups. The organosiloxane may consist of units: where each R is the same or different monovalent hydrocarbon radical, each R1 is H or the same or different alkyl radical of less than 6 carbon atoms, n has an average value of 0.90 to 1.90 and m has an average value of 0.1 to 1.5. The organosiloxane may be a dialkyltrialkoxytrisiloxane or a phenylalkylsesquisiloxane in which the alkyl and alkoxy radicals contain 1-6 carbon atoms. Toluylene diisocyanate is a suitable polyisocyanate. The aliphatic monocarboxylic fatty acid ester of a polyhydric alcohol may include a different carboxylic ester group of the same alcohol. The different ester group may be derived from (i) aliphatic, saturated polycarboxylic acids, aliphatic unsaturated carboxylic acids containing at least 4 C atoms and aromatic polycarboxylic acids as well as (2) aliphatic saturated carboxylic acids containing at least 2 carbon atoms and ethylenically unsaturated monocarboxylic acids containing at least 3 C atoms and aromatic carboxylic acids.ALSO:Surfaces of metal, e.g. Al, Mg or steel, plastics, e.g polypropylene, polyethylene terephthalate or poly vinyl fluoride and wood are coated with a composition which comprises the reaction product of: (1) 40-90% by wt. of an aliphatic monocarboxylic fatty acid ester of a polyhydric alcohol in which the alcohol portion has at least two free OH groups; (2) 5-40% by wt. of an organo-siloxane having at least one free OH and/or alkoxy group; and (3) 5-40% by wt. of an organic polyisocyanate. (see Division C3). The coating composition may also comprise from 1-30% by wt. per part by wt. of resin of an organic or inorganic pigment, e.g. phthalocyanine orange, molybdate orange, chrome yellow, ZnO, TiO2, Cr2O3, carbon black or flaked aluminium. The coatings may be hardened by baking, e.g. at 250-400 DEG F for 30 mins. to 1 1/2 hours.
