What Is the Difference between PVDF Coating and Powder Coating?
There are customers who do not know the difference between PVDF coating and powder coating and do not know whether they should choose PVDF coating or powder coating. We are pleased to provide a brief overview of PVDF coating, powder coating, and the differences and benefits of PVDF coating and powder coating.
What is PVDF coating?
PVDF coating (polyvinylidene fluoride) a resin based liquid coating system and a pure thermoplastic fluoropolymer that is non-reactive and possesses multiple coating benefits. PVDF coatings are especially resistant to solvents, acids and have a very low density compared to similar fluoropolymers.
What is Powder coating?
Powder coating is Electrostatic spraying refers to a coating method that uses the corona discharge principle to make atomized coating negatively charged under the action of a high-voltage direct current field and adsorbed on the surface of a positively charged substrate.
Difference and performance comparison
1). Different raw material
PVDF coating raw material is Polyvinylidene fluoride
Powder coating raw material is various such as Epoxy resin, Epoxy-polyester mixture, Polyester resin, Polyurethane resin, Polyvinyl chloride (PVC), polyethylene.
2). Different process
Fluorocarbon spraying process is divided into :
Two coating a baking (referred to as two coating) : primer + finish + curing.
Three coating a baking (referred to as three coating), primer + finish + finish + curing.
Four coating two baking (referred to as four coating), primer + isolation blocking paint + curing + finish + varnish + curing
Powder Coating Process Involves Three Basic Steps
Part preparation or the pre-treatment, the powder application, and curing.
