摘要： 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 percent to 100 mol percent of isophthalic acid and/or 0 to 100 mol percent terephthalic acid, or a mixture thereof, with a polyol mixture comprising at least one dial and at least one polyol having at least three hydroxyl groups. The thermosetting powdered coating compositions provide coatings with low gloss levels that can be adjusted from a gloss level of less than 1 to 40 or less, when measured at an angle of 60 degrees.
