With the improvement of national environmental protection requirements, coil steel industry is facing the change from paint to powder. However, the coil steel requires special properties on curing, flow, gloss and weatherability etc. Traditional powder coatings are difficult to achieve the balance of these properties. At present, through the development of different types of polyester resin, Shenjian has been able to meet the requirements of coil steel industry in high and medium gloss products. Meanwhile, we are looking forward to cooperating with anyone who is interested in the development and promotion of powder coating for coil steel.
