摘要

The present invention relates to a coating agent comprising a polyester and a pouring agent containing at least one hydroxyl tube powder, and more preferably a cellulose ester, a crosslinking agent, a polystyrene resin, a catalyst additive, a modifier, an epoxy resin, a pigment, a filler, a filler, a pigment, a filler Hydroxyl tube-containing powder ester having a weight average molecular weight of 40,000 to 200,000 and a polydispersity of more than 8, made from at least 50% by weight of aromatic dicarboxylic acid or an esterifiable derivative thereof, in which case up to 80% by weight of phthalic acid the total amount of acid rock opener used, the branching point of the hydroxyl tube-containing polyester is 0.6-1.21000 g of solid polyester, and / or the KOH is preferably 50 mg, 50 mg of hydroxyl tube powder. and / or the acid number of the polyester containing the hydroxyl tube is 5 to 20 mgKO H / g, preferably 10-15 mg KOH / g, and / or amine number 0-40 mg KOH / g. ŕ
