POWDER COATING COMPOSITION

摘要

The present invention provides a powder coating composition comprising an intimate mixture comprising (A) 60 to 99 wt% of a mixture comprising at least one polyester resin and at least one (meth) acrylate resin, (B) 0 to 30 wt% of at least one cross-linking agent, (C) 0.1 to 10 wt% of at least one pigment, whereby component (A) and component (C) are selected in such a way that the powder coating composition provides a low gloss of the cured coating in the range of 1 to 20 gloss units at 60° angle according to DIN 67530 (ISO2813) and at the same time provides a surface structure of the cured coating characterized by a value of Integral 1 in the range of higher than 8.00E+00 measured by the mechanical profilometry Fourier analysis, and whereby the wt% are based on the total weight of the powder coating composition. The powder coating composition according to the invention provides the desired special metallic effect of the coated surface which meets the metallic effect resulted with anodized aluminium.
