PURPOSE:To obtain the subject composition excellent in weatherability, acid resistance, adhesivity to base materials by incorporating a composition comprising a fluororesin and a curing agent reactive with the crosslinkable reactive group in the resin with e.g. a synthetic wax or the like at specified proportion. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100 pts.wt. of a resin composition comprising (1) 60-97wt.% of a fluororesin having crosslinkable reactive group >=10wt.% of fluorine content, 35-120 deg.C in glass transition temperature, 20-140mgKOH/g in hydroxyl value, 3-140mgKOH/g in acid value and 300-14000g/eq in epoxy equivalent and (2) 3-40wt.% of a curing agent capable of forming crosslinks by reacting with the crosslinkable reactive groups in the component 1 with (B) 0.01-10 pts.wt. of a synthetic wax or natural wax 50-280 deg.C in melting point. It is preferable that 1-50wt.% of the component 1 be replaced with a thermosetting powder coating resin such as a polyester resin or acrylic resin. |
