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.

The optimum amount to be added must be established in preliminary trials. If the application has been interrupted for long periods, the spraying nozzles should be cleaned with water or aqueous caustic soda.

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 must be stored in the tightly closed original container. Stir well before taking emulsion from drums. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
