Ultra-weather resistant powder coating

PVDF is a semi-crystalline fluorocarbon， it is combined by fluorocarbon bond an chemical structure, and this kind of short bond structure could be the most stable and the strongest combination with hydrog gen; meanwhile, it's a thermoplastic processing plastic of higher molecular weight, the coating which is sprayed by fluorocarb bon that is made up of 70% PVDF resin,with the incomparable super weather resistance property and processing technic,cou uld use more than 20 years, soit is the first choice of metal surface treatment for high-rise building or the extremely harsh enviro onment constructional engineering.

: Super weather resistance and chemical resistance properties.

: Environmental, no emission and recyclable.

: Non-toxic and safe: food grade.

: Good in mechanical and physical properties.
