The role of surface-coating ATH

Aluminum hydroxide as an inorganic filler and polymeric material are not identical in physical form and chemical structure level, and the affinity between them is extremely poor. In order to change its surface activity, surface coating treatment is generally carried out by adding a suitable large surfactant or coupling agent to achieve the following purposes.

1)Increase the surface activity - increase the affinity between aluminum hydroxide and resin

force and improve physical and mechanical properties.

2)ncrease the amount of aluminum hydroxide incorporation - to increase the flame retardancy and reduce the cost of the product.

cost of the product.

3)Reducing the moisture absorption rate on the surface of aluminum hydroxide.
