HF-687 Chemical Additives Silica Powder For Coil

SKYSIL HF-687 SILICA MATTING AGENT FOR COIL COATING In the industrial coating of coil coating, the balance between matting efficiency and coating surface performance is a technical difficulty. HF-687 matting agent provides a cost-effective matte solution for coil coating with its large particle size design of 10-11 microns and surface optimization process, taking into account both production efficiency and terminal quality. - Large particle size advantage (10-11 microns): HF-687 uses narrowly distributed large particle size silica to significantly improve the matting efficiency. Under the same gloss (adjustable from 20° to 70°), the addition amount is 20%-30% lower than that of traditional products, reducing the formulation cost. The large particle structure simultaneously enhances the wear resistance of the coating, with a friction coefficient of ≤0.18 (ASTM D1894), which resists mechanical wear during coil processing. - Surface dense coating technology: The particle surface…
