Protective polymer coating
Description of steel sheet polymeric coverings.
Polyester (polyester enamel)
Polyester is one of the most popular polymeric coatings for zinc-coated steel sheet. This is relatively reasonable material, which is proper for any climatic regions. Polyester is resistant for mechanical and weather impacts.
Polyester features high colour permanence and plasticity. Polyester covering can be glossy and mat.
PVDF (PVF2) – is the material consisting of 80 % of polyvinylfluoride and 20% of acryl. Polymeric covering is strong and resistant to frost up to -60°C and keeps its characteristics up to +120С. It is the most resistant to ultraviolet radiation, practically no colour fade, has beautiful luster. In comparison with other coverings it is the most expensive one and features high resistance to aggressive environments and mechanical impacts.
Pural is a new type of a polymeric covering on a polyurethane basis inoculated by polyamide. This material has good chemical stability, resistant to solar radiation, high temperatures and large daily temperature drops. Thickness of covering is 50 microns. This covering is flexible; therefore, it is easily processed during forming and installation. It reserves ductility properties even at low temperatures. Thickness of covering is 25 microns.
Plastisol 200 microns is a high quality covering system with cladding imitating skin texture. It has distinctive decorative characteristics. The basis of the covering is PVC (polyvinyl chloride). It is known for its high abrasion resistance, good incorrodibility, and excellent flexibility and, as consequence, stability against scratches. Choosing plastisol for using in hot regions, orientate yourself with respect to light colors. They reverberate light better, heat up and discolor not so much. Due to heavy gauge of covering, it is recommended to use in high pollution density conditions.
