GAYNUT - Y® CNSL (Cashew Nut Shell Liquid) based refractory mortar is a thermosetting resinous cement designed for industrial applications requiring high resistance to corrosive environments. This non-porous, self-hardening mortar achieves an impermeable dense cement structure upon setting and cooling, ensuring remarkable durability and chemical resistance. It withstands exposure to acids, acidic salts, alcohols, grease, fats, mineral oils, alkalis, and hydrofluoric acid up to 40% concentration. GAYNUT - Y® is specially formulated for bedding and jointing acid-proof bricks and tiles used in high-corrosion areas such as reaction vessels, storage tanks, neutralization pits, and flooring surfaces. The product is ideal for industries including steel, dyestuff, metal finishing, thermal power plants, paper, fertilizers, petrochemicals, food processing, beverages, breweries, and dairies. Its superior bond strength and flexural strength provide a reliable solution for piping systems that transport corrosive fluids like acids, alkalis, solvents, and oils. Notably, GAYNUT - Y® is not recommended for use with certain solvents or at temperatures exceeding 100°C, ensuring users apply it within optimal conditions. With export-grade quality, this mortar adheres to international industrial standards, making it a dependable choice for global markets.

GAYNUT – Y® CNSL (Cashew Nut Shell Liquid) base Mortar is a Non-porous, self-hardening and relatively plastic in nature. When GAYNUT-Y® set and cooled, impermeable dense cement is obtained. It is hardened by chemical reaction. It is thermosetting resinous cement. It resists acids, acidic salts, alcohols, grease, fats, mineral oils & alkalis. IT resists hydrofluoric acid up to 40% concentrations. GAYNUT – Y® is not recommended for certain solvent and in situations where the temp. Is more than 100 0CUseGAYNUT – Y® can be used in laying (bedding) and pointing (joint filling) of acid proof bricks and tiles for the construction of acid resistant tank linings, flooring surfaces, GAYNUT – Y® can be safely used as jointing material for jointing pipes line transporting corrosive fluids like alkalis, solvents, acids and oils. Acid Resisting Bricks / Tiles Lining based on GAYNUT-Y® is recommended for severe corrosive conditions as in reaction vessels, storage tanks, neutralization pits, drains, floors and other areas.GAYNUT-Y® is used in different industries like Steel, Dyestuff, Metal Finishing, Thermal Power Plants, Paper, Fertilizers, Petrochemicals, Food processing, Beverages, Breweries, Dairies etc.For severe corrosion conditions GAYNUT-Y® is used fir bedding and jointing of tile / bricks and for less sever conditions, it is used as a pointing material along with silicate cement [GAYREX®] as the bedding material.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)PropertiesPROPERTY UNIT VALUE(after7Days)Compressive Strength, min.: Kg/Cm2 : 360Bond Strength, min. : Kg/Cm2 : 12Flexural Strength, min.: Kg/Cm2: 79Water Absorption, min: (% by Weight): 0.9Co-ef of Expansion: Engineered for international industrial buyers, this refractory mortar ensures durability, performance, and export compliance.
