  • Patent number: 10683424
    Abstract: A method of forming a low gloss, high solids polyurea coating containing very low volatile organic compounds (VOC) in the coating composition. The low volatile content not only makes the coating environmentally friendly but allows it to be applied at variable thickness levels and over a wide variety of environmental conditions. The coating composition is comprised of an isocyanate reactive agent containing a secondary diamine, a polyisocyanate, a gloss reducing agent and a viscosity modifier. The gloss reducing agent is generally pre-mixed into an isocyanate reactive agent containing a secondary diamine and/or polyisocyanate containing the viscosity modifier before mixing the two components together to form a low gloss polyurea coating.

  • Patent number: 10556985
    Abstract: Amine-epoxy curing agents are disclosed including at least one saturated heterocyclic compound having two nitrogen heteroatoms according to formula (I) and at least one saturated fused bicyclic heterocyclic compound having three nitrogen heteroatoms according to formula (II): wherein X is independently selected from a hydrogen atom, a linear or branched C1 to C4 alkyl group and a substituted or un-substituted phenyl group, Y1 is a direct bond or a divalent polyethylene polyamine group having 1 to 8 nitrogen atoms or a divalent polyethylene polyamine derivative having 1 to 8 nitrogen atoms, Y2 is a direct bond or a divalent polyethylene polyamine group having 1 to 7 nitrogen atoms and R is independently a hydrogen atom or a group selected from C1-C8 linear, cyclic, and branched alkyl, alkenyl, and alkaryl groups.

  • Patent number: 7342068
    Abstract: Aqueous polyurethane dispersions comprising polyurethane polymer and methods for making and using same are disclosed herein. In one aspect of the present invention, aqueous polyurethane dispersions, comprising a polyurethane polymer having a weight average molecular weight ranging from 20,000 to 80,000, are prepared by controlling the weight average molecular weight of the polymer by reacting the isocyanate terminated prepolymer with at least one chain terminating agent; and/or maintaining a N/COOH molar ratio of amine in the neutralizing agent to acid functional group in the isocyanate reactive compound to from about 0.5:1 to about 1:1.
