  • Process for preparing water-dilutable, heat-curing epoxy resin coating compositions using organic cosolvents
    Patent number: 4104224
    Abstract: An improved process for preparing with the aid of organic cosolvents water-dilutable, heat-curing coating compositions comprises (a) reacting an aromatic polyglycidyl ether with a polyethylene glycol in the presence of 10 to 30% of a polyhydric phenol, (b) adding an aminoplast curing agent, and (c) diluting with water to give a stable aqueous or aqueous organic composition.The process gives compositions which are useful in preparing coatings for a wide variety of substrates.
    Type: Grant
    Filed: November 22, 1976
    Date of Patent: August 1, 1978
    Assignee: Ciba-Geigy Corporation
    Inventors: Robert C. Nelson, John Allister Gannon, Kwan Ting Shen
  • Process for preparing water-dilutable, heat-curing coating compositions
    Patent number: 4048179
    Abstract: A process for preparing water-dilutable, heat-curing coating compositions comprises (a) reacting an aromatic polyglycidyl ether with a polyethylene glycol in the presence of 0 to 20% of a polyhydric phenol, (b) adding an aminoplast curing agent, and (c) diluting with water to give a stable aqueous composition.The process gives compositions which are useful in preparing coatings for a wide variety of substrates obviating the need for organic solvents with their inherent costs and environmental hazards.
