  • Patent number: 4794147
    Abstract: This invention, therefore, relates to the field of polyurethane coatings for use in automobile basecoat/clearcoat systems. In particular, this invention relates to water-dispersible polyurethane resins having polyether sidechains which may be utilized in basecoat compositions as principal resins or grind resins. These polyurethane resins may be laterally stabilized or terminally stabilized. The terminally stabilized resins of this invention are preferably employed as principal resins in basecoat compositions.

  • Patent number: 4728676
    Abstract: A thermosetting reactive resin mixture is made from an organic polyisocyanate, a polyepoxide and a heat activatable catalyst. The catalyst is a tertiary or quaternary ammonium salt of an alkylating or acidic ester of an organic phosphonic acid or of phosphoric acid. The polyisocyanate and polyepoxide are used in quantities such that the equivalent ratio of isocyanate groups to epoxide groups is from 1.2:1 to 70:1. These mixtures may be heated to produce plastics having excellent heat resistance, moisture and abrasion resistance, low dielectric losses and excellent molding properties.
