聚氨酯型粉末涂料Polyurethane powder coating
聚氨酯粉末涂料正发展成为粉末涂料的主流，在粉末涂料中所占的比例越来越大，由于聚氨酯粉末涂料具有优良的耐候性、优良的物理力学性能和防腐蚀性，涂膜光亮丰满、耐磨、耐划伤、耐溶剂，流平性好、附着力强。
Polyurethane powder coating is developing into the mainstream of powder coating, which accounts for a larger and larger proportion in powder coating. Due to the excellent weather resistance, excellent physical and mechanical properties and corrosion resistance, polyurethane powder coating is bright and plump, wear-resistant, scratch resistant, solvent resistant, smooth, strong adhesion.
特点Features
⑴熔融流平时，熔融黏度低，特别是封闭剂在解封之前不起任何化学反应，使粉末涂料有足够的流平时间，涂膜流平性好。新的内封闭型脲二酮固化剂技术的实现，使得这种粉末涂料对空气的污染几乎为零；⑵对被涂物的附着力好，不需要底涂；⑶涂料的配制范围宽，可以配制不同性能要求和固化速度的涂料；⑷涂膜的物理力学性能和耐化学品性能好。
After the melt flow, the melt viscosity is low, especially the sealant before unsealing without any chemical reaction, so that the powder coating has enough leveling time, film leveling.The realization of the new internal sealed urea diketone curing agent makes the air pollution of the powder coating almost zero.The adhesion of the coating is good, do not need the primer;The preparation range of the coating is wide, can be prepared with different performance requirements and curing speed of the coating;In addition, the coating film has good physical and mechanical properties and chemical resistance.
