It is the most widely used plastic in the world, being made into products ranging from clear food wrap and shopping bags to detergent bottles and automobile fuel tanks.” When used in coating, it has an overall advantage in accessibility, affordability, color variety, and corrosion resistance.
“A popular high quality resin used for metal roof coatings. SMP resins are created by blending polyester with silicone intermediates and ceramic pigments. This formulation results in a superior color and gloss retention as well as increased weather resistance when compared to poly resins.”
The molecule of the HDP material is 1000 times smaller than that of PE, giving it superior flexibility and processability. Filled with ceramic beads, it has a hard surface. With UV-Ray resistant and hydrophobic additives, HDP coating is perfect for environment with strong UV ray or heavy moisture.
”It is the most commonly used commercial and industrial coatings on the market. PVDF is a fluoropolymer resin that is highly inert and stable, providing excellent resistance from metal weathering over time. They are widely used when a durable coating is needed on project exteriors to resist weathering, chalking, fading, and UV rays while offering exceptional protection to the substrate.”
Service life of different coatings on galvanized steel (in years)
*Please note that service life of steel sheets are mostly influenced by the substrate. Coating only plays a partial role. For example, a galvalume substrate will largely enhance the service regardless of paints.
