Protecto W-40 is an Acrylic Polymer Additive for modifying cement concrete/mortar/plaster/grouts. Protecto W-40 in conjunction with cement provides properties to combat the shortcomings of cement, particularly its poor adhesion properties, low impact strength, low flexural strength and thin section fragility. The addition of Protecto W-40 improves mechanical properties specially flexure and tension. Due to low permeability of polymer-modified systems, remarkable improvement in prevention of carbonation, chloride ion penetration is observed. Also chemical resistance improves significantly. The addition of Protecto W-40 imparts resilience to the cement matrix, thereby improving impact resistance. Also the modified cement matrix cures in air, eliminating the necessity of wet curing. It is necessary to mix Protecto W-40 in water first prior to addition in cement mortar/concrete.
