Corrostain™ 228 – Corrosion Inhibitive Pigment
Corrostain™ 228 features a unique pigment chemistry which combines the dual functionality of Corrosion Inhibition and Tannin Stain Inhibition. This dual functionality aids in the reduction of raw material inventories and also provides effective inhibitor formulations. It is designed to provide good stability and performance in both solvent and water based systems. Typical use level is between 2 – 6% based upon total formula weight.
