GAYNUT - Y ® (CNSL Mortar)
Acid and Alkali Resistant Cement Mortar
GAYNUT - Y is a Silica filled, cashew-nut oil base resin. Non-porous, self-hardening and relatively plastic in nature. When GAYNUT-Y set and cooled, impermeable dense cement is obtained.
GAYNUT - Y is resistant to a wide range of acid, alkalise, water, hydrofluoric acid up to 40% concentrations: GAYNUT-Y provides an excellent Protection against hydrofluoric and nitric acids in the treatment of stainless steel (where tank lining are constructed with CARBON BRICKS)
GAYNUT - Y can be used in laying and pointing of acid proof bricks and tiles for the construction of acid and alkali resistant tank linings, flooring surfaces, GAYNUT - Y can be safely used as jointing material for jointing pipes line transporting corrosive fluids like alkalies, solvents, acids and oils.
