TUFCHEM Silicate Gunite is an inorganic, two component, 100% potassium silicatebonded gunite applied lining. Properly installed, TUFCHEM Silicate Gunite yields a strong, dense, acid-resistant lining which protects concrete and steel substrates from most oils, solvents, and a wide range or corrosive acids. It is not resistant to acid fluorides, hydrofluoric acid, or alkaline environments. TUFCHEM Silicate Gunite is usually installed with an anchoring system. Consult Corrosion Engineering specification CES322 and CES329 for complete installation details.
