JIS G3321 0.85mm Marble grain Pre-finished PPGL Prepainted Galvalume color-coated Steel HDP Beckers for cladding
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:
For the shortcomings of PE and SMP, HYDRO (now acquired by BASF) and BECKER of Sweden developed a 60-80% weatherable HDP polyester coating that can achieve PVDF coating in early 2000, and is superior to ordinary silicon modification.
This coating has an outdoor weather resistance of 15-18years.The coating has excellent weather resistance, corrosion resistance and solvent resistance, UV resistance, processability, and a tough and durable aesthetic color.HDP coating is suitable for area with high temperature and less industrial pollution.
