Inhibisil® 73

Chemical Family
Silica

Inhibisil® 73 anti-corrosion pigment is a calcium oxide-containing synthetic amorphous silicon dioxide. It is designed for use where thin film anti-corrosive protection is needed. Its high calcium oxide content, ease of dispersion, and high Hegman value provide formulation flexibility and expanded process capability.
