B 1 17) Anti-fading, anti-pulverization and anti-dust adhesion. It can be seen that the total service life of such colored steel tiles will not be less than 50 years! Polyester (PE) has good adhesion, wide formability and outdoor durability, moderate chemical resistance and a service life of 7- 10 years.
Silicon modified resin (SMP) film has good hardness, wear resistance and heat resistance, good external durability and non-pulverization, limited gloss retention and flexibility, and its service life is 10- 15 years.
High weatherability polyester (HDP) has excellent ultraviolet resistance and high durability. Its main properties are between polyester and fluorocarbon, and its service life is 10- 15 years.
Polyvinylidene fluoride (PVDF) has good formability and color retention, excellent outdoor durability and pulverization, solvent resistance, limited color and service life of 20-25 years.
