Product feature
Pre-painted galvanized sheets contain PVDF more than 70%. The coating has good weather resistance, acid-proof, and environment polluting resistance, keeps the coating has the gloss and color retention, in various climate, its service life can reach more than 30 years.
Suggested used
Architecture:Our products an be use for all kinds of climate conditions of outdoor environment and buildings, such as roof and cladding, especially high inclined roof structures or huge, which requires atmospheric pollution resistance heat and strong sunlight-proof.
Transportation industry:Subway station, car outer, highway road signs, etc.
Others:All kinds of protection panel in electronics factory, laboratory and hospital for anti-static, purification room
Attention
Because fluorocarbon resin coating is polyester and soft, Please pay attention in the process of installation.
product Size
Z180 PVDF25/10um
Basic material
pre-painted sheet substrate production is used 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 coating 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.
