SILRES® BS 1052

1 of 110 products in this brand
SILRES® BS 1052 is an aqueous and water-dilutable emulsion of a medium-viscosity polydimethylsiloxane. Its main purpose is to provide water repellency to materials such as glass wool (fiberglass) or stone wool. It can be used on both bound materials, where the wool is bound with a resin, as well as unbound materials without a resin. By applying SILRES® BS 1052, it helps to enhance the water-repellent properties of these materials, improving their performance in moisture-related applications.

Application Details
  • SILRES® BS 1052 has to be stirred well before use. A moderate stirring equipment running at medium speed is sufficient – high shear force and air entrainment are not necessary and must be avoided.
  • SILRES® BS 1052 is applied via spraying equipment after the fiberizer. For this purpose it can be diluted with any quantity of water. If the glass or stone wool substrate is a resin-bound material, after compatibility test SILRES® BS 1052 is mixed with the resin mixture and the mixture is sprayed onto the wool.
  • It can also be sprayed separately without mixing using a second spraying equipment. 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. Individual tests must always be conducted in order to define the necessary quantities.
  • For Blowing Wool an overdosage of silicone emulsion can lead to a change in consistancy of the wool which might lead to blocked injectors in the end application of the blowing wool.
