Powder Coating Grades
LUMIFLON LF-710F was developed specifically for use in powder coatings. It’s high Tg means that it blends easily with other components of powder coating formulations, including pigments, isocyanates, and additives. Powder coatings made with LF-710F offer the same outstanding weatherability as LUMIFLON liquid coatings.
Application Areas
- Architecture
- Coil coating
- Curtain wall coatings
