  • Coating surface of hydrophobic microporous thermal insulation material
    Patent number: 5474806
    Abstract: A surface of a hydrophobic microporous thermal insulation material is coated by first heating the surface of the microporous thermal insulation material so as to provide a hydrophilic surface layer on the hydrophobic material. Subsequently, a water-based coating, such as a water-based silicate adhesive, is applied to the hydrophilic surface layer of the hydrophobic material. An abrasive-and/or impact-resistant cover, such as a glass fibre cloth, may be applied to the coating.
