摘要： The present invention is directed to a powder coating composition that produces a low gloss coating upon cure. The powder coating composition includes one or more crosslinkable base polymer, a crosslinkable acrylic polymer and one or more free radical initiators. By adding spheroidal particles to the powder coating composition further reduction in gloss can be obtained while improving smoothness. These compositions are well suited to produce coatings on metallic substrates, such as automotive bodies and non-metallic substrates, such as reconstituted wood substrates, used for desk or table tops.

摘要： Coating agents with resin solids of(a) 10 wt-% to 80 wt-% of a non-aromatic polyester polyol,(b) 0 wt-% to 70 wt-% of at least one constituent selected from the group consisting of hydroxyl-functional binders that are different from polyester polyol (a), hydroxyl-functional reactive thinners and combinations thereof, and(c) 20 wt-% to 60 wt-% of at least one cross-linking agent for the hydroxyl-functional components (a) and (b),wherein the polyester polyol (a) has a calculated molecular mass from 600 to 1400, an acid value from 0 to 30 mg KOH/g and an hydroxyl value from 250 to 600 mg KOH/g with a calculated hydroxyl functionality from 4.5 to 10, and is composed of components which comprise (a1) hydroxyl components comprising 0 wt-% to 20 wt-% of at least one diol and 80 wt-% to 100 wt-% of at least one polyol having 3 to 6 hydroxyl groups, (a2) carboxyl components comprising 0 wt-% to 20 wt-% of at least one monocarboxylic acid and 80 wt-% to 100 wt-% of at least one dicarboxylic acid, and optionally (a3) at least one hydroxycarboxylic acid component,the sum of the percentages by weight of components (a) to (c), of components (a1) and of components (a2) being 100% in each case.

摘要： The invention relates to binding agents which are suitable for use in coating agents. Said binding agents are obtained by reacting one or more epoxide-functional binding agents with carboxyl-functional nanoparticles. The invention also relates to coating agents containing said binding agents and the use thereof.

摘要： A binder composition suitable for coating agents, containing A) 20 to 77 wt.% of binder based on oligomeric or polymeric polyol compounds with a hydroxyl number from 80 to 300, an acid number of 0 to 30, a number average molecular weight (Mn) of 500 to 10,000 and a glass temperature of -20 to + 70 DEG C; B) 77 to 20 wt.% of a cross-linking agent based on aliphatic and/or cycloaliphatic polyisocyanates, C) 3 to 20 wt.% of carboxyl group-containing oligo or polyesters as a catalyst resin with an acid number of 210 to 300 mg KOH/g and a number average molecular weight (Mn) of 420 to 3,000, and one or more organic solvents and/or water.
