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.
Properties
SILRES® BS 1052 shows high thermal stability. Due to its viscosity in the medium range it is well pumpable and dilutable despite its high solid content.
Data sheets
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 % by weight for stone wool and 0.1 and 0.3 % by 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.
