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.
Claims19
A method for making an unbound loose-fill silicone-coated mineral wool, the method comprising:
- providing a loose-fill mineral wool comprising a collection of loose mineral wool fibers;
- applying to the loose-fill 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 40 kDa;
- and
- allowing the solvent to evaporate to provide silicone-coated mineral wool,
- wherein the rate of application of the coating composition to the mineral wool is in the range of 0.1-10 mg silicone per gram mineral wool,
- wherein the mineral wool is at a temperature in range of 200-500° C. when it is coated with the solvent-borne coating composition.
