  • Patent number: 5866262
    Abstract: Dipcoated Rx spectacle lenses require coating scratch resistance, tinting and/or AR coating processes. Chemically, fully-hydrolized copolymers of amino silane and epoxide silane form the chemical backbone of these heat-curing hardcoats, although polyfunctional organic resin modifiers may also "co-cure" into the backbone. The liquid coating copolymer is made in three chemical reactions: (1) fully hydrolizing the two silane Components A&B separately, with a stoichemetric excess of water; (2) ketimine formation, to latently cap the amine functionality; (3) "bodying" the liquid hardcoating to a desired degree of copolymerization, by reacting together the fully hydrolized ketimine silane Component B with the fully hydrolized epoxide-functional silane Component A. Dilution is with the selected resin modifier(s) ketone and alcohol solvent. The resin modifier has at least two organo-functional reactive groups per molecule, of epoxide or melamine or hydroxyl or urea families.

  • Patent number: 4351919
    Abstract: Polyester silicate resinous products are produced by chemically reacting an organosol containing organic polyhydroxy compounds with an organic polycarboxylic acid and/or polycarboxylic acid anhydride. An excess of oxidated silicon compound may be used in this process. The unsaturated polyester silicate resinous products may be used to produce building panels, boats, furniture, etc.
