POWDER COATING ADDITIVE, POWDER COATING COMPOSITION CONTAINING SAID ADDITIVE AND METHOD FOR COATING A SUBSTRATE USING SAID POWDER COATING COMPOSITION

摘要

A powder coating additive composition containing (a) a non-crosslinked product made by the reaction of an organic alcohol and a carboxylic acid or a reactive equivalent of the carboxylic acid; the product containing at least one ester functionality and at least one hydrocarbyl group of about 10 to about 100 carbon atoms; and (b) a fluoropolymer. The cured coatings exhibit lower coefficient of friction and substantial gloss retention.
