SILRES BS 16

SILRES® BS 16 is an aqueous solution of potassium methyl siliconate and is used in diluted form for the impregnation of mineral construction materials to make them water-repellent. SILRES® BS 16 develops its water-repellent properties by reaction with atmospheric carbon dioxide(CO2). As with all siliconates, however, SILRES® BS 16 can cause a white deposit on the surface of colored construction materials, or if used outside the application guidelines. SILRES® BS 16 imparts water repellency to: • low-fired clay products immediately after they have been made: e. g. roof tiles, facing bricks, floor tiles, flower pots • aerated concrete • gypsum and gypsum-based fiber boards • light fillers, such as perlite, vermiculites and aerated concrete granules • insulating materials Applications • Boards & Panels • Construction Materials • Gypsum Wallboards and Gypsum Fiberboards • Hydrophobic Impregnation • Pre-Impregnation of Construction Materials
