2 Synthesis and application of powder FEVE fluorocarbon resin

The structure design of powder FEVE fluorocarbon resin is similar to that of similar solvent-based resins.

For many fluoropolymer production, such as F30, F40, etc.

Powder FEVE fluorocarbon resin can be synthesized by any of the polymerization processes including suspension polymerization, solution precipitation polymerization, and solution polymerization

Table 6 Main technical indicators of powder FEVE fluorocarbon resin

Compared with ordinary powder coatings, FEVE fluorocarbon powder coatings networked cross-linked structure gives the coating film better weather resistance, aging resistance and corrosion resistance.

Facing the ever-increasing market demand, stricter building standards and environmental protection pressure, fluorocarbon modified carboxyl polyester formulations can no longer meet the rigidity requirements of many customers

The matting of powder coating formulations includes physical matting and chemical matting

Remarks: The temperature of the extruder in the first zone is 95℃, and the temperature in the second zone is 105℃

Due to the high cost and price, pure FEVE fluorocarbon powder coatings are destined to be the noble products in powder coatings, which can meet very few high-end building materials quality projects

3 Conclusion

With the continuous deepening of research and development of water-based industrial coating resins, water-based resins with new structures will continue to emerge to meet the needs of high-performance water-based industrial coatings
