Abstract: Thermosetting resins containing hydroxyl groups which can be cured with aminoplast resins are stabilized by the addition of 1,4-diazo[2,2,2]-bicyclooctane. This method is particularly useful in stabilizing the gloss retention of extensible coatings formed by curing a hydroxyl-containing urethane product with an aminoplast resin. Such coatings can be applied to virtually any solid substrate and are especially useful on rubbery, resilient substrates such as polyurethane or polyethylene foam, natural or synthetic rubber or rubber foam, and various elastomeric plastic materials. They are also particularly useful on other substrates such as mild steel or aluminum.

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.

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 water-dispersed polyurethanes of the present invention are excellent film formers, capable of making coatings with a wide spectrum of desirable properties.
