  • Water-based two layer coating systems based on urethane, the use thereof and substrates coated with them
    Patent number: 8299164
    Abstract: Disclosed is an aqueous clearcoat material for producing a waterborne urethane-based two-coat coating system, comprising at least one secondary polyacrylate dispersion having a polyacrylate glass transition temperature Tg?20° C. and at least one hybrid polyacrylate-polyurethane dispersion with a weight ratio of the polyacrylate fraction of the secondary dispersion to the polyacrylate-polyurethane fraction of the hybrid dispersion of 1:1 to 4:1, and as curing agent at least one low-viscosity aminosulfonic polyisocyanate and an aqueous basecoat material for producing a waterborne two-coat coating system comprising at least one polyurethane dispersion, at least one hybrid polyacrylate-polyurethane dispersion, and at least one melamine resin. Also disclosed are a waterborne two-coat coating system comprising the clearcoat material and the basecoat material, a process for producing it, its use to coat a substrate, and substrates coated with it.

  • WATERBORNE URETHANE-BASED TWO-COAT COATING SYSTEMS, USE THEREOF AND SUBSTRATES COATED WITH THEM
    Publication number: 20100324199
    Abstract: The present invention relates to an aqueous clearcoat material for producing a waterborne urethane-based two-coat coating system, which comprises at least one secondary polyacrylate dispersion having a polyacrylate glass transition temperature Tg?20° C. and at least one hybrid polyacrylate-polyurethane dispersion with a weight ratio of the polyacrylate fraction of the secondary dispersion to the polyacrylate-polyurethane fraction of the hybrid dispersion of 1:1 to 4:1, preferably 2:1 to 3:1, more preferably 2.25:1 to 2.75:1, and as curing agent at least one low-viscosity aminosulfonic polyisocyanate and an aqueous basecoat material for producing a waterborne two-coat coating system which comprises at least one polyurethane dispersion, at least one hybrid polyacrylate-polyurethane dispersion, and at least one melamine resin.
