SILRES BS 97

SILRES® BS 97 is a water-dilutable silicone resin emulsion and used to impart water repellency to mineral insulation materials. SILRES® BS 97 is especially suited for the water-repellent treatment of expanded mineral materials (vermiculites, perlites, clay) and of fibrous insulating materials based on minerals or plants (coconut fibers, glass, basalt, slags). SILRES® BS 97 is diluted with water in a ratio of 1:10 to 1:19 and applied by spraying. Best substrate temperatures range from 50 to 200°C. For the core impregnation of insulating materials SILRES® BS 97 is usually added to the binder system, followed by a short-term heat treatment of 100 - 180°C. Mineral fiber boards are best impregnated by dipping and then drying at approx. 100°C.
