Ultra fine powder coatings technology 20KGPOLYFINE 9000

Ultra Fine Powder Coatings Technology
Ultra fine powder coatings Technology is a unique invention of Technology, which makes ultra fine powder coatings with a particle size of 15 microns compared to 30-50 microns in normal powder coatings. Ultra fine powder coatings can make exceedingly thin and smooth coating surfaces and represents breakthrough technology in the powder coatings industry.
Ultra fine Coating Before Baking
Ultra fine Coating After Baking
Ultra fine powder has finer particle size and can obtain a more uniformly thin coating surface.
Ultra Fine Polyester Powder Coatings
Polyfine 9000 is high durability powder coatings specially formulated for use on exterior environment on a variety of substrates. Polyfine 9000 gives excellent exterior durability and color retention performance and conforms with the performance requirements of AAMA2603.. Polyfine 9000 is used where resistance to environmental conditions is required (curtain wall frames, window frames, claddings and residential doors etc) as well as indoor product. Polyfine 9000 is available in a selected range of colors RAL, in all gloss range finishes and textured effects can be custom matched to the user’s need. Polyfine 9000 is ultra fine powder coatings leading to outstanding smooth surface and thin coating.

10 minutes at 200 °C or 20 minutes at 180 °C
0% failure (no loss) on Dry and Wet Adhesion test of AAMA 2603. 6.4.
No removal of film from substrate, AAMA 2603, 6.5.
1500 hrs no corrosion area more than 2mm from scribe ASTM D 1654
1500 hrs - no blister>size of N0 8, figure of No 4, ASYM D 714
ASTM G53/77 (500 hours) Excellent performance.Slight even loss of gloss; no checking, cracking, flaking or chalking. Chalking None in excess of minimum in
ASTM D659: 1980 - Color change None in excess of one Munsell Step.
(Florida exposure 45 °S. exposure 45 °N) Pass one year with standard of performance as in artificial weathering test above.
Mechanical tests carried out on chromated aluminum panels. All tests performed on panels coated with 30 to 60 microns of a gloss finish powder cured for 10 minutes at 200 °C. Reduced gloss finishes may show lower values for mechanical performance.
For maximum protection it is essential to pretreat architectural components prior to the application. Aluminum extrusions must coat a chromate conversion.
Polyfine 9000 can be applied by manual or automatic electrostatic spray equipment, however for consistency of finish automatic equipment is preferred. Unused powder can be reclaimed using suitable equipment and recycled through the coating system.
