Abstract: Disclosed are essentially zinc-free, organic coating compositions based on silicon-containing polyols comprising reaction products of hydrophobic polyols, organosilicon-containing materials, and higher monohydric alcohols, R-OH. The organosilicon-containing material comprises an organosilicon-containing substance free of certain functional groups attached directly to carbon and essentially free of alkali metal ions. The organosilicon-containing substance has atoms bonded directly to Si all of which are selected from O, N, and/or Cl. The organosilicon-containing substance also has moieties directly bonded to Si which are displaceable by reaction with water and/or alcohol. The reaction product is not capable of being gelled when subjected to a specific gel test, has a content of hydroxyl groups from the hydrophobic polyol ranging from 0.4 to 10 milliequivalents per gram of reaction product, has a content of groups, --OR, from the higher monofunctional alcohol ranging from 0.

Abstract: Low organic solvent-containing coating compositions are prepared by blending (i) an ester-containing polyol, having a number average molecular weight of from about 140 to about 700, a hydroxyl value of from about 160 to about 1100 and a viscosity of less than about 1200 poises, which is derived from an aromatic or alicyclic monobasic acid and, optionally, a minor proportion of a polybasic acid and a polyol having an average hydroxyl functionality of from about 2.1 to about 5.0 with (ii) an aminealdehyde crosslinking agent. Particularly valuable coating compositions which can be cured at relatively low temperatures are obtained by incorporating a cure accelerating catalyst into the composition. The compositions aid in environmental pollution control and form films having good adhesion, flexibility, hardness, stain resistance, detergent resistance, solvent resistance and durability.
