Nowadays, constructions widely use polymer-based cements due to their good adhesive qualities and resistance to moisture, acids and bases. The phosphorus modified-CNSL polymeric resin highly suits this requirement. This polymer sticks well on to the surface of porous bricks, concrete and steel. They can be easily set at low temperatures by the slow and gentle addition of heat. CNSL-based polymers can also be found useful in sealing leaks present in the roofs. These CNSL-based polymers on being mixed with a curing agent forms a putty which can be filled into the cavities of the leaks in order to seal them.
