| Product description: SILRES® BS 1042 is an aqueous emulsion of a reactive polydimethylsiloxane. It is used to impart water-repellency to glass wool mat or rock wool mat bound with phenolic resin or to low-density bulk goods such as perlite or vermiculite. Application: To impart water repellency to glass wool or rock wool, SILRES® BS 1042 can be mixed with the phenolic resin solution or other additives. As the stability of the obtained mixtures greatly depends on the composition of the phenolic resin or the additives, no general comments can be made on compatibility. With suitable equipment, SILRES® BS 1042 can either be applied at the same time as or shortly before application of the binder. Treatment of glass wool mat or rock wool mat with SILRES® BS 1042 after drying and hardening is not recommended. Information provided by Wacker Chemie AG. |
