SILRES® BS 5140 is an aqueous and water-dilutable emulsion of aminofunctional polydimethylsiloxane. It is used to provide water repellency to mineral insulation materials, particularly binder-free mineral wool, also known as blowing wool. Beside the hydrophobation of binder-less mineral wool, so-called "blowing wool, SILRES® BS 5140 can also be used at lower temperatures or for post-treatment of mineral wool.
