  • Aqueous composition with improved elongation at break
    Patent number: 10167408
    Abstract: An aqueous polymer composition which when in the form of a film shows excellent elongation at break comprising (i) 5 to 30 wt. % of polyurethane where the acid value of the polyurethane is between 3 to 40 mg KOH/g; (ii) 70 to 95 wt. % of vinyl polymer comprising 20 to 90 wt. % of vinyl polymer with Tg<20° C.; 10 to 80 wt. % of vinyl polymer with Tg?20° C.; where at least one of the vinyl polymers contains acid functional groups with acid value in the range of from 15 and 240 mg KOH/g.
    Type: Grant

  • Primer for coating coiled wires
    Patent number: 8795830
    Abstract: Disclosed is a method to provide a metal wire with a coating system comprising a primer and a topcoat, particularly a hydrophilic, lubricious topcoat. The method comprises applying directly onto the wire metal a primer coating composition, which is an aqueous coating composition comprising a multiphase vinyl polymer, the polymer comprising a first phase having a Tg in the range of from ?20° C. to 40° C. and a hard phase having a Tg in the range of from 25° C. to 120° C. The primer has good adhesion to both the metal surface and the topcoat, and provides the eventual coating system with, inter alia, a good flexibility.
