In all the chemical buildings, the bond energy between fluorine and carbon is the strongest. The strong UV light is hard to destroy the chemical bond energy between the fluorine and carbon. At this basis, the durability and UV resistance of the water-based fluorocarbon are the best in the similar exterior wall product. The resistance to artificial aging time can easily reach 2000H. When the primary level construction meets the specification, the effect of outdoor protection and decoration can stand at least above 20 years; 2. It has an excellent performance on corrosion resistance and chemical resistance, suitable for special harsh environments; 3. It has a strong adhesion to any kinds of primary level; 4. It has an excellent stain resistance, can be natural and clean in long-term; 5. It has a strong metallic effect; 6. It has an excellent waterproof performance and scrub resistance.
