SILRES BS 1052

SILRES® BS 1052 is an aqueous and water-dilutable emulsion of a medium-viscosity polydimethylsiloxane. It is used to impart water repellency to glass wool (fiber glass) or stone wool bound with a resin, or unbound without a resin. SILRES® BS 1052 shows high thermal stability. Due to its viscosity in the medium range, it is well pumpable and dilutable despite its high solids content. Based on the glass or stone fiber mass the addition ratio varies between 0,05 and 0,2 weight % for stone wool and 0,1 and 0,3 weight % (always based on the weight of the dried final product) for glass wool. The quantity of SILRES® BS 1052 to be applied also depends on the desired water repellency of the end product given.
