  • Publication number: 20110034628
    Abstract: Disclosed are branched polyols (A) having two or more hydroxyl groups per molecule prepared by providing a polyisocyanate (A1) containing per molecule two or more isocyanate groups and either two or more hard segments (a11) which as part of a thermoset three-dimensional network raise its glass transition temperature, or two or more soft segments which as part of a thermoset three-dimensional network lower its glass transition temperature; and reacting the polyisocyanate (A1) with a polyol (A2) in a molar ratio (A2):(A1) of ?2 and an equivalent ratio of [X+OH]:NCO?2; wherein polyol (A2) has the general formula I: X [—R(—OH)n]m, and the variables have the following definitions: n is a number from 1 to 5, m is 1 or 2, X is an isocyanate-reactive functional group, and R is a divalent to pentavalent organic radical, with the proviso that R comprises at least one hard segment (a11) if (A1) comprises soft segments.

  • Patent number: 6747091
    Abstract: The invention relates to an intrinsically viscous powder-slurry that can hardened by actinic radiation or optionally by thermal means, which contains solid spherical particles with an average particle size of 0.8 to 20 &mgr;m and a maximum particle size of 30 &mgr;m. The clear powder coating slurry contains 0.05 to 1 meq/g of ion-forming groups and 0.05 to 1 meq/g of neutralizing agents and has a viscosity of (i) 50 to 1000 mPas at a shear rate of 1000 s−1, (ii) 150 to 8000 mPas at a shear rate of 10 s−1, and (iii) from 180 to 12000 mPas at a shear rate of 1 s−1.
