  • Patent number: 10066301
    Abstract: A method of coating the surface of a metal substrate includes a) applying a first composition on the surface of a metal substrate, the first composition being a solution comprising a liquid medium including sol-gel precursors of alcoxysilane type or of metallo-organic type; b) subjecting the first composition to first heat treatment to form an anchor layer on the metal substrate in which the sol-gel precursors are bonded to the metal substrate, a first temperature being imposed during the first heat treatment that is sufficient to eliminate all or part of the liquid medium and to encourage the bonding of the sol-gel precursors to the metal substrate; and c) applying a second composition on the anchor layer. The second composition includes coating compounds to obtain a coating on the anchor layer by forming bonds between the sol-gel precursors and the coating compounds.

  • Patent number: 10064792
    Abstract: A hybrid coating material and process for pigments and other powders, for example cosmetic powders employs an organometallate, for example a titanate, and a functionalized silicon compound, for example a trialkoxysilane or a functionalized polysiloxane, which covalently bond to each other and to the substrate powder. The coated powders can exhibit excellent hydrophobicity coupled with lipophilicity. Employment of fluorinated silicon compounds may provide hydrophobicity and lipophobicity. Examples show good dispersibility of coated pigments in aqueous, oil and silicone fluids.
