Abstract
Water-dispersible salt-containing containing quaternary ammonium salt groups are prepared by reacting a polyglycidyl ether of a polyphenol and an amine acid salt. When dispersed or dissolved in water, the quaternary ammonium salt-contaning resins can be applied to a wide variety of different substrates by electrodeposition, and will deposit on the cathode to provide coatings of unique properties.
Claims16
A boron-free, water-dispersible, quaternary ammonium salt-containing resin suitable for use in electrodeposition comprising the reaction product of:
- A. a polyglycidyl ether of a polyphenol, and
- B. an amine acid salt,
- the weight ratio of said amine acid salt to said polyglycidyl ether being from about one part to about 50 parts by weight of salt per 100 parts by weight of said polyglycidyl ether, said amine salt reacted with said polyglycidyl ether of a polyphenol in an amount and at a temperature below about 110.degree.C. and sufficient to provide a quaternary ammonium salt-containing, water-dispersible resin.
An aqueous dispersion comprising a boron-free, water-dispersible, quaternary ammonium salt-containing resin suitable for use in electrodeposition comprising the reaction product of:
- A. a polyglycidyl ether of a polyphenol, and
- B. an amine acid salt,
- the weight ratio of said amine acid salt to said polyglycidyl ether being from about one part to about 50 parts by weight of salt per 100 parts by weight of said polyglycidyl ether, said amine salt reacted with said polyglycidyl ether of a polyphenol in an amount and at a temperature below about 110.degree.C. and sufficient to provide a quaternary ammonium salt-containing, water-dispersible resin.
