Method of preparing homogeneous thermosetting powder paint composition |
摘要 |
A method of preparing a homogeneous thermosetting powder paint composition which cures to form a coating exhibiting outstanding exterior durability, adhesion and impact strength. The method comprises: introducing a liquid including at least a crosslinkable copolymer and an inert solvent into a devolatilizing zone wherein the inert solvent is removed and the nonvolatile material is separated in a molten state; feeding said nonvolatile molten material under pressure into a heated mixing zone comprising a static mixer; simultaneously feeding a stoichiometric quantity (+/- 30%) of a molten crosslinking agent for said copolymer into said mixing zone under pressure; removing the mixture of nonvolatile molten material and molten crosslinking agent from said mixing zone; cooling said mixture to form a solid material; and purlverizing the solid material to form a powder.
