Advantages Of Our  Suede PPGI
1. Resistance  to acid rain:
Coating protection mechanism: It is very easy to form acid rain in the high  level of industrial emissions or pollutants environment. Acidic penetration is  formed in the surface of pre-painted steel, and accelerates the corrosion,  forming blistering, peeling and so on.
2. Resistance  ultraviolet rays:
Coating protecting  Mechanism: pre-painted sheet in ultraviolet or strong sunlight conditions, the coating will exhibit chalking degeneration, manifested as discoloration and  loss of gloss, lose paint quickly.
3. Resistance to humid heat:
Coating protecting  mechanism: in hot and humid environments, high osmotic pressure of water vapor accelerates penetration, forming the degeneration of painting film, then the  corrosion of the substrate, with the phenomenon of bubbles and peeling.
4. Resistance to low temperature:
Coating protecting  mechanisms: most of the paint can keep stable processing performance above 0 degree, but at alpine region, the temperature will be below 20-40 degree,  normal paint will become brittle,bend cracking, or even lose paint, thus  protection function is lost totally.
