Patent ID: 10766825

Abstract:
A composition comprising a self-dispersible mixture additive composition comprising a alkylalkoxysilane of formula (RO)4-nSiR′n, or its hydrolysate or mixture thereof, where, R is same or different C1-C20, R′ is same or different C1-C20; mixture of non-ionic emulsifier of HLB value between 8 and 20. The self-dispersible mixture additive composition is obtained by mixing the alkyltrialkoxysilane with a mixture of non-ionic emulsifier. The emulsion of the self-dispersible mixture additive composition is formed by mixing appropriate amount of an aqueous solvent to the self-dispersible mixture additive composition, and addition of thus formed emulsion to a porous product preferably dry cement to render uniform and long lasting hydrophobic property of the final product made of the porous product.
