Now a growing number of construction company use more prepainted steel sheet replacing the real natural materials like wood, brick , marble. But some clients know a little about it ,Today let me shortly introduce the paint of prepainted steel sheet.
The most used paint have 4 kind that is PE, SMP,HDP,PVDF.
1)PE(polyethylene) paint : Good comprehensive performance, it’s good weather ability and mechining performance meet the requirements of exterior building.
Supporting two kinds of primer
EPOXY primer : epoxy system primer, with excellent corrosion resistance and adhesion.
PU Primer : Polyurethane Primer with excellent machining and corrosion perforance, versatile primer.
Range of application : Industrial buildings, commercial buildings such as outdoor parts: roof, external walls.
2)SMP paint : Silicone Modified Polyester Color Coatings
Features : Add special silicone polyester resin and crosslinking agent to ensure the ability of weather resistance ; And ultra-weathering pigments to ensure that permanent bright of the color; special silicone structure to enhance the hardness of coating thus increasing wear resistance and metal Scratching, also it can withstand the processing of stamping
3)HDP (High durability polyester) paint :
The use of high-performance polyester resin and inorganic ceramic pigments, can do a lot color which PVDF can not do; special polyester structure, good hydrolysis resistance, the use of weather-class pigments,increasing it’sexcellent chemical resistance and durability;
4)PVDF (polyvinylidene fluoride) color coated products
More than 70% of the polyviny lidene fluoride content, it make the coating has a good weather resistance, acid and alkali and environmental pollution performance; paint use advanced inorganic ceramic pigments, blocking the UV, maintain the coating has a gloss color retention; also it has excellent mechining properties: such as T bend up to 0-2T.
So suggest used the right paint according to the different weather, different environment, different application.
