PTFE Molding Powder

PVDF not only has the general properties such as high toughness, low friction coefficient and excellent oxidation resistance, also has unique functional properties including piezoelectricity, dielectricity and pyroelectricity.

PVDF application usually include:

● Coatings

● Lithium-ion battery binders

● Photovoltaic backsheet films

● Water treatment filtration

PVDF coating powder can be processed by electrostatic spraying.

Besides, it is widely adopted for manufacturing fluorocarbon coating, which are formulated with 70% PVDF resin, 30% acrylate resin and inorganic pigments. 

With over 40 years of application history, PVDF fluorocarbon coating has proven to be a premium coating material for metal architecture, delivering superior weathering protection for buildings.

Conventional coatings suffer from short service lives when exposed outdoors. Prolonged outdoor exposure often causes fading, gloss loss, corrosion and chalking. In contrast, PVDF fluorocarbon coating retain the buildings’ original appearance even under long-term outdoor service.

Why do PVDF fluorocarbon coating offer exceptional long-term weather resistance?

1.PVDF fluorocarbon coating is formulated from fluoropolymer PVDF resin.

2.PVDF resin is a polymer constructed with alternating -CH₂- and -CF₂- groups that form a compact and stable chemical structure. The bond energy of the C–F bond stands at 485 kJ/mol, higher and more stable than most chemical bonds. C–F bonds hardly break under heat or ultraviolet radiation, which accounts for the coating’s outstanding long-term weather resistance and chemical corrosion resistance.

Fluorocarbon coatings made with PVDF resin comply with the American architectural material standard AAMA 2605 and China’s industrial standard HG/T 3793-2019.

Powder fluorocarbon coating has emerged in 1976, to alternate the liquid fluorocarbon coating which has heavy pollution to environment. Due to the limited ultra-fine powder technique, its development is slow. Today, powder fluorocarbon coating can achieve the thickness and surface smoothness comparable to liquid fluorocarbon coating. Meanwhile, it has solved the long-standing problem of high cost.

Powder coatings can form thicker films than liquid coatings, making them more suitable for harsh environments such as regions with intense sunlight exposure.

PVDF fluorocarbon coating advantages

● Retain the exceptional weather resistance and chemical corrosion resistance of traditional solvent-based PVDF fluorocarbon coating, but also offer superior hardness and scratch resistance. 

● Can provide a thicker coating that ensures better coverage of the substrate. 

● Do not emit volatile organic compounds (VOCs) during production or application.

● Comply with stringent environmental regulations, belong to market's eco-friendly products.
