<p>The present invention provides a powder coating composition comprising
(A) 40 to 99 wt% of at least one saturated carboxylic functional polyester resin,
(B) 1 to 60 wt% of at least one glycidylester and/or glycidylether selected from the group consisting of polyglycidyl ethers based on aliphatic, aromatic and/or cycloaliphatic epoxy resins, triglycidyl trimellitate (TML) and diglycidyl terephthalate (DGT), and
(C) 0,01 to 40 wt% of at least one coating additive, pigment and/or filler,
the wt% being based on the total weight of the powder coating composition. In spite of substitution of TGIC, the powder coating composition of this invention are coating compositions having a good storage stability and giving coatings with good coating properties, particularly, high exterior durability and stable flexibility.</p> |
