COMPOSITION FOR FLUORORESIN POWDER COATING MATERIAL

摘要

A composition for fluororesin powder coating materials with which a coating film having an excellent matte effect is obtained without impairing features of fluororesins including excellent weatherability and a process for producing the composition. The composition for fluororesin powder coating materials comprises two or more hardening systems which each comprises a fluororesin having crosslinkable sites and a hardener reacting with the crosslinkable sites and in which the hardening systems substantially independently react and crosslink. This composition is characterized in that the crosslinking reaction time for one hardening system is different by at least 20 seconds from the crosslinking reaction time for the other hardening systems.
