Abstract
Official abstract text for this publication.
A powder coating composition comprising a specific organosilicon compound forms a coating which exhibits satisfactory water-loading resistant performance.
First claim
Opening claim text (preview).
The invention claimed is: 1. A powder coating composition comprising (A) an organosilicon compound having the general formula (1): wherein R 1 is each independently a C 1 -C 10 alkyl or C 6 -C 10 aryl group, R 2 is each independently a C 1 -C 10 alkyl or C 6 -C 10 aryl group, A is a C 1 -C 20 divalent hydrocarbon group, B is a C 1 -C 20 divalent hydrocarbon group, and m is an integer of 1 to 3, and (B) a resin selected from the group consisting of epoxy resins, polyester resins, epoxy-polyester resins, acrylic resins, fluoro-resins, and silicone resins, wherein the organosilicon compound is contained in an amount of 0.1 to 5 parts by weight, provided that the powder coating composition is 100 parts by weight. 2. The powder coating composition of claim 1 wherein the organosilicon compound has the general formula (2): wherein R 1 , R 2 , and m are as defined above. 3. The powder coating composition of claim 1 , wherein resin component (B) comprises a carboxyl-containing polyester resin. 4. The powder coating composition of claim 1 , further comprising (C) a β-hydroxyalkylamide compound. 5. A coated article obtained by coating a substrate with the powder coating composition of claim 1 .
