Abstract
The present disclosure relates to silicone-coated mineral wool insulation materials, methods for making them using specific coating methods, and methods for using them. One aspect of the disclosure is a method for making a silicone-coated mineral wool, the method comprising: providing a mineral wool comprising a collection of mineral wool fibers; applying to the mineral wool a solvent-borne coating composition comprising a silicone, the silicone of the coating composition having a number-average molecular weight of at least 25 kDa; and allowing the solvent to evaporate to provide silicone-coated mineral wool.
