| Product description: SILRES® BS 66 is a liquid oligomeric siloxane which is intended primarily for in-plant water-repellent treatment of aerated concrete. It may also be diluted with organic solvents for use as a water repellent for facades. Application: Undiluted SILRES® BS 66 serves as a water-repellent admixture for aerated concrete. Even when added in very small quantities, it dramatically reduces water absorption, and also optimizes the concrete's pore structure. When used as a water repellent for facades, SILRES® BS 66 is diluted with organic solvents. The resulting solutions are characterized by their good depth of penetration and excellent resistance to alkalis. The product may be applied to practically all absorbent mineral substrates, such as bricks, sand-lime brick, concrete, natural stone, mineral paints and plasters. When the main focus is a pronounced beading effect, it is preferable to use the all-round water-repellent agent SILRES® BS 290. Information provided by Wacker Chemie AG. |
