Keminject WB

Keminject WB is an aqueous solution of innovative siliconate resin used in diluted form for the impregnation of mineral construction materials to make them water-repellent. Keminject WB develops its water-repellent properties through a reaction with atmospheric carbon dioxide (CO₂). The active substance formed from the silicone masonry water repellent is polymethylsilicic acid. As with all siliconates, however, Keminject WB may cause a white deposit on the surface of colored construction materials.
