High solid coil coating

High solid coating is a new type of energy saving and environmental protection coating developed to meet the needs of modern painting development, especially to comply with environmental protection to reduce VOC  New emission requirements; Our company

Successful research and development; Series of high solid paint, in addition to meet all the requirements of conventional coating aluminum coil, but also has the characteristics of higher film fullness, better gloss stability.   Compared with conventional coatings, the advantages of high solid containing coatings are mainly reflected in two aspects:

1. Due to the factory viscosity remains unchanged (110 seconds /25 degrees), solid content increased by 15%, its unit square coating rate significantly improved, compared with ordinary coating comprehensive increase of 15%-20%, effectively reduce the coating   Cost, enhance the market competitiveness of customers;

2. The volatile solvent of high solid content coating is about 25% lower than that of ordinary coil coating, greatly reducing VOC  Emissions, reduce environmental pollution, but also slow down the environmental pressure faced by enterprises.
