which paint is better for the ppgi,color coated steel,PE paint,HDP paint,PVDF,SMP paint

According to the type of coating and coating surface effect, color coated steel plate can be divided into PE paint, HDP high weather resistance paint, PVDF paint, SMP paint, sand surface color coated board, reticulated color coated board, etc..  

PE polyester paint is made of high temperature baking metal paint color coating board.  
 
Performance characteristics: good comprehensive outdoor durability and coating properties (flexibility, hardness, etc.);  Moderate chemical resistance;  Wide choice of color and luster;  General with epoxy paint primer, excellent adhesion;  
 
Application: medium cost, high cost performance, but its corrosion resistance, uv resistance and anti-powder performance is general, only suitable for ordinary building roof, wall, not for serious corrosion environment  

PVDF paint is the use of carbon resin content of more than 70% carbon coating on the metal plate, and then made of high temperature baking metal color coating board.  
 
Performance characteristics: the coating is made of inorganic pigment with excellent durability and carbon resin with strong corrosion resistance, which can effectively resist the erosion of ultraviolet rays and corrosion factors.  With good flexibility of polyurethane primer, the coating has excellent processing performance, T-bending performance can achieve 0-2T;  But because of uneven chromatography, not suitable for too bright color;  The service life can reach 20-25 years.  
 
Application: due to its high price, it is generally used in areas requiring high corrosion resistance and coating aging resistance  

SMP silicon modified polyester color coating board is a metal paint color coating board made of SMP silicon modified resin ester coating coated on metal plate and then baked at high temperature.  
 
Performance features: excellent outdoor durability (light and color);  Good coating properties: hardness, wear resistance, heat resistance;  Good chemical resistance;  Slightly less flexible than polyester;  Durability 10-15 years.  
 
Application: medium to high cost, mainly suitable for wear resistance, durability requirements of outdoor buildings.
