  • Adjustable low gloss powder coating compositions
    Patent number: 10450479
    Abstract: Thermosetting powdered coating compositions comprising (a) a high Acid Value carboxylic acid functional polyester resin having an Acid Value of at least 100 mg KOH/g and a functionality of at least 4.5, (b) a low Acid Value carboxylic acid functional polyester resin having an Acid Value of 20 to 50 mg KOH/g and a functionality of about 2.5 or less, and (c) a cross-linking agent. The high Acid Value polyester resin is the reaction product of a polycarboxylic acid or its anhydride reacted with a polyester polyol obtained from reacting 0 mol % to 100 mol % of isophthalic acid and/or 0 to 100 mol % terephthalic acid, or a mixture thereof, with a polyol mixture comprising at least one diol and at least one polyol having at least three hydroxyl groups.
