SILICA Anti-Corrosive Pigment

Description:

HCAC 30 is a type of ion exchanged silica as anti corrosion pigment. The main content is silicon, so it is non-toxic and with no heavy metals. It can pass the current environmental protection regulations and is a safe and environmentally friendly anti corrosion pigment.

Properties

- Environmentally friendly anti corrosion pigment, no chromium, no heavy metals

- with longer effective anti corrossion :

- Improve film density, inhibit foaming and permeability;

- The synergistic effect of anti-corrosion is obvious, and it has higher advantages with other active anti-corrosion fillers and pigments;
