WIPO Patent Application WO/2001/025346

Kind Code:

A1

Abstract:

A powder coating composition comprising a fluorocopolymer (A) having crosslinking reactive groups and a curing agent (B) capable of reacting with the crosslinking reactive groups to form crosslinks at an (A)/(B) weight ratio of 40/60 to 98/2 and containing rutile titanium dioxide and other pigments. This composition can form paint films exhibiting excellent weathering resistance even under extremely severe environmental conditions as stipulated in AAMA2605, thus being suitably applicable particularly to exterior cladding members for building, e.g., aluminum sashes.
