Among various coatings, fluororesin coatings have particularly superior properties due to the large electronegativity of the introduced fluorine element and strong carbon-fluorine bond energy, such as weather resistance, heat resistance, low temperature resistance, and chemical resistance. Unique non-stick and low friction.

1. Excellent anti-corrosion performance - thanks to the excellent chemical inertness, the paint film is resistant to acids, alkalis, salts and other chemicals and various chemical solvents, it provides a protective barrier for aluminum profiles; the paint film is tough - high surface hardness, impact resistance, buckling resistance, good wear resistance, showing excellent physical and mechanical properties.

2. Maintenance-free, self-cleaning - fluorocarbon coating has extremely low surface energy, surface dust can be self-cleaned by rainwater, excellent hydrophobicity (maximum water absorption rate is less than 5%) and oil repellency, extremely small friction coefficient (0.15 - 0.17 ), the aluminum profile will not stick to dust and scale, and has good antifouling performance.

3. Strong adhesion - it has excellent adhesion on the surfaces of aluminum, copper, stainless steel and other metals, polyester, polyurethane, vinyl chloride and other plastics, cement, composite materials, etc., and basically shows that it should be attached to any material. characteristics. High decorative - In a 60 degree glossmeter, it can achieve a high gloss of more than 80%.

4. Ultra-long weather resistance - the coating contains a large number of F--C bonds, which determines the superior stability of aluminum profiles, no chalking, no fading, and a service life of up to 20 years, which is more durable than any other type of coating better performance.
