Using high-performance polyester resin and inorganic ceramic pigment, effectively reduces the coating film degradation rate, it can improve the performance of coating resistance and make coating surface more stable. Compared with the ordinary PE, SMP silicone modified polyester, it has better chemical resistance and durability. JIUMEI products series can be used for 20 years under the condition of direct exposure.
Suggested used
Suitable for general buildings, commercial buildings, outdoor house.
Such as roof, cladding, etc.
Attention
JIUMEI series is based on galvanized sheet, the incision is better than that of aluminum coated zinc protective base material. But it is not recommended to use in very bad environment. Such as serious coastal Marine pollution industries or regions, which is suggested to choose PVDF fluorocarbon series of our company.(PVDF fluorocarbon series).
product Size
Z180 HDP25/10
Basic material
JIUMEl pre-painted sheet substrate production use Sino Master hot dip galvanized steel coil, the thickness and tolerance can meet customer demand. Surface quality is according to the home appliance base board, with good smoothness and good adhesion
Coating technology
Using two roasting roller coating curing process.
Coating Technology
Passivation treatment is used the Henkel surface treatment to make film on surface of coating, which is with good corrosion resistance and paint adhesion.
Transport requirement
Transport vehicles should be clean, and Use professional lifting tools, pay attention to shake, indentation, pollution prevention, collision, preventing the sliding.
Store requirement
The storage environment of Steel roll and products should ensure that not in outdoor and changeable temperature, storage area should be flat, and has enough bearing capacity, at the same time should avoid the multi-layer stacking haulms and products with big external force.
Used request
Because of the influence of the long-time, the physical and chemical properties of steel will change with the extension of storage time, lead to formability and coating will change accordingly, in order to avoid bad effect, it is suggested that user to use as early as possible.
