SILRES®BS 280 CF is a solvent-free silicone concentrate based on silane/siloxane that is dilutable with organic solvents. Diluted solutions of SILRES®BS 280 CF are high-quality water repellents for impregnating mineral building materials, especially silicate free natural stones like limestone or gypsum. It develops its water repellent effect after application to construction materials as a result of a reaction with atmospheric humidity. SILRES®BS 280 CF is a Catalyst-free version of SILRES®BS 280. Properties : • good penetration into building materials • extremely effective with most natural stone • good alkali resistance (alkaline mortar joints) Applications : • Hydrophobic Impregnation • Impregnation of New and Existing Buildings SILRES® BS 280 CF should be diluted in a ratio of 1:11 (parts by weight). It can be diluted with aliphatic and aromatic hydrocarbons or with anhydrous alcohol. We would especially recommend the use of petroleum hydrocarbons such as white spirit.
