The organosilicon-containing material comprises an organosilicon-containing substance free of functional groups attached to carbon and essentially free of alkali metal ions, having atoms bonded directly to silicon, all of which atoms are selected from O, N, and/or Cl. The organosilicon-containing substance additionally has moieties directly bonded to silicon which are displaceable by reaction with water and/or alcohol. At least a part of the organosilicon-containing substance is hydrolyzed to a compound or a mixture of compounds containing a residual amount of the moieties directly bonded to silicon which are displaceable.The reaction product is not capable of being gelled according to a specific three-step gel test; has a ratio of milliequivalents of the residual displaceable moieties to milliequivalents of hydroxyl moieties from the polyol greater than 1, and is capable of self-curing to a continuous film in the presence of moisture.

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.

Abstract: Quaternary ammonium hydroxide-containing polymers and their use in cationic electrodeposition are disclosed. The quaternary ammonium hydroxide-containing polymers are particularly useful as feed resins for controlling the pH of aqueous dispersions of acidified cationic resins used in electrodeposition. Upon electrodeposition, such resins generate acid which can build up to undesirable levels in the electrodeposition bath. The quaternary ammonium hydroxide-containing polymers are strong bases and when fed into the bath react with the acid to form the corresponding quaternary ammonium salt. This controls the pH of the bath at acceptable levels and provides additional cationic resin for electrodeposition. Utilizing the invention in this manner minimizes the need for controlling acid build-up in the electrodeposition bath by conventional techniques such as by treating the bath with ultrafiltration or electrodialysis.The quaternary ammonium hydroxide-containing polymers are also useful as electrodeposition resins themselves in that they electrodeposit without generating acid counter ion.

Abstract: A water-diluted, ungelled, non-sedimenting polyurethane and a process for preparing such a polyurethane in the presence of water is disclosed. The polyurethanes are prepared so that they contain a high percentage of highly active hydrogens which enable the polyurethanes to be further reacted with a curing agent to form thermoset products. The polyurethanes of the present invention are prepared by first dispersing a partially reacted NCO-containing polymer in water, which is then chain extended with a material such as an organic diamine. Thermosetting compositions are made by adding curing agent to the chain extended material. Curing agents can also be incorporated into the polymer molecule either in the making of the partially reacted NCO-containing prepolymer or by further reaction with the partially reacted NCO-containing prepolymer. The water-dispersed polyurethanes of the present invention are excellent film formers, capable of making coatings with a wide spectrum of desirable properties. In addition, they can be added to other water-compatible compositions to improve flexibility, hardness, drying and other coating properties.
