| Product description: 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). The active substance formed from the silicone masonry water repellent is polymethylsilicic acid. 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. Application: Imparting 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
