Classification and uses of fluorocarbon paint

Fluorocarbon paint mainly includes three major types, ① fluorocarbon resin paint (PEVE) ② polyvinylidene fluoride fluorocarbon paint (PVDF) ③ polytetrafluoroethylene fluorocarbon paint (PTFE). These three major types of coatings have different applications in different fields.

1. Fluorocarbon resin coating (PEVE)
PEVE fluorocarbon paint is mainly used in heavy-duty anti-corrosion fields, and is most widely used in the anti-corrosion of steel structures and bridges. It is a high-end coating product among current anti-corrosion paints.
Main performance features: super weather resistance, outstanding salt spray resistance, good stain resistance and self-cleaning properties.
PEVE fluorocarbon paint is self-drying and curing at room temperature and does not require baking and drying. It can be made into solid color topcoats, metallic paints and varnishes. Mainly equipped with zinc-rich primer, epoxy primer, mica iron intermediate paint, etc.

2. Polyvinylidene fluoride fluorocarbon paint (PVDF)
PVDF fluorocarbon paint is a high-temperature baking product, which generally includes primer and topcoat, and is baked for 15 minutes at 230°C. This fluorocarbon paint is mainly suitable for aluminum plates, aluminum alloys, stainless steel and other base materials. The paint film is metallic in color, has good metal texture, beautiful appearance and excellent decorative properties. It is widely used in the field of aluminum veneer curtain walls.
Main performance characteristics: Very good solvent resistance, chemical resistance, UV resistance, high mechanical strength, and excellent heat resistance.

3. Polytetrafluoroethylene fluorocarbon paint (PTFE)
PTFE fluorocarbon paint is generally called non-stick coating or easy-to-clean coating. The surface has very good self-cleaning properties and adhered dirt is easy to clean. The coating is acid and alkali resistant, resistant to various organic solvents, high temperature resistant, and has a very low friction coefficient. It is mainly used for coating the inner wall of non-stick pans or the interior of some pipe fittings.
Main performance features:
High temperature resistance: working temperature reaches 250℃.
Low temperature resistance: It has good mechanical toughness; even if the temperature drops to -196°C, it can maintain an elongation of 5%.
Corrosion resistance: It is inert to most chemicals and solvents, and can withstand strong acids and alkalis, water and various organic solvents.
