Coating types of color steel sheet
Common types of top coatings used for color coated steel sheets are polyester coating (PE), fluorocarbon coating (PVDF), silicon modified coating (SMP), high weather resistant coating (HDP), acrylic coating, Polyurethane coating (PU), plastisol coating (PVC), etc.The most common coatings are PE,SMP,HDP and PVDF coating.
PE coating is shorted for Polyester coating,which has good adhesion to materials, and make color coated steel sheets be easily processed and formed. Because of cheap price and wide range of color and gloss,this coating type is widely used in many products.The substrate could be hot dipped galvanized steel,hot dipped galvalume steel. Life span, under normal environmental exposure,the corrosion protection period can be as long as 10-12 years.
SMP coating is shorted for Silicone Mobified Polyester coating.Since the polyester contains an active group -OH/-COOH, it is easily reacted with other macromolecular substances. The modified PE is resistant to sunlight and powdering, and is denatured by a Silicone resin having excellent color retention and heat resistance. Life span, SMP provides better durability for steel sheetsand the corrosion resistance can last for 12-15 years.
HDP coating is shorted for High-durability Polyester coating.The high weathering polyester resin is synthesized by using a monomer containing a cyclohexane structure to achieve the flexibility, weather resistance and cost balance of the resin, and the aromatic-free polyol and polybasic acid are used to reduce the absorption of UV light by the resin. To achieve high weather resistance of the coating. UV coatings and hindered amines (HALS) are added to the coating formulation to improve the weather resistance of the film. High weathering polyester coil coatings have been recognized in the market abroad, and the cost performance of the coatings is very prominent. Life span, this coating has an outdoor weather resistance of 15-20years.
PVDF coating is short for Polyvinylidene fluoride.Due to the strong bond energy between the chemical bonds and chemical bonds of PVDF, the coating has very good corrosion resistance and color retention,which make PVDF coating be the most advanced product in the color coating steel construction industry.The molecular weight is large and the direct bond type structure, so in addition to chemical resistance, mechanical properties, ultraviolet resistance and heat resistance are also prominent. Life span, PVDF coating has an outdoor weather resistance of 25-30years.
