Abstract
A composition for fluororesin powder coating material, with which a coating film having an excellent matte effect is obtainable without impairing features of fluororesins including excellent weather resistance, and a process for its production, are presented. The composition for fluororesin powder coating material comprises at least two curing systems each comprising a fluororesin having crosslinkable sites and a curing agent reactive to the crosslinkable sites, wherein the respective curing systems substantially independently react and crosslink, and the crosslinking reaction time of one curing system is different by at least 20 seconds from the crosslinking reaction time of other curing system(s).
