  • Patent number: 10689544
    Abstract: Fiber coatings with low Young's modulus, low fiber pullout force for fibers in the as-drawn state, and small time-dependent increases in pullout force as the fiber ages. The fiber coatings are cured products of coating compositions that include an oligomer formed from an isocyanate, a hydroxy acrylate compound and a polyol. The oligomer includes a polyether urethane acrylate and a di-adduct compound. The reaction mixture used to form the oligomer includes a molar ratio of isocyanate:hydroxy acrylate:polyol of n:m:p, where when p is 2, n is in the range from 3.0 to 5.0 and m is in the range from 1.50n-3 to 2.50n-5. Control of the n:m:p ratio leads to compositions that, when cured, provide coatings and cured products having low Young's modulus, low pullout force on glass, and weak variations with time as the fiber ages.
    Type: Grant

  • Patent number: 10377915
    Abstract: A treated monomer for optical fiber coatings, a coating composition containing the treated monomer, a coating formed from a coating composition containing a treated monomer, and a fiber coated with the coating formed from a coating composition containing a treated monomer. The monomer is an alkoxylated alkyl acrylate and is formed by acrylating a polyol precursor. The monomer may include residual unreacted polyol precursor. The monomer is treated with a derivatizing agent to convert residual unreacted polyol to a derivative form. The derivative form is less susceptible to degradation to the corresponding non-alkoxylated alcohol or other lower alkoxylated alcohol. The treated monomer includes the alkoxylated alkyl acrylate and the derivative form of the polyol.

  • Publication number: 20170146732
    Abstract: Methods of applying adhesion promoters to optical fibers are described. The methods include direct application of an adhesion promoter onto the surface of the optical fiber. The adhesion promoter is applied in liquid form as a neat compound or as a component of a liquid solution to the surface of the optical fiber. The adhesion promoter bonds to the optical fiber and includes functional groups that permit bonding with an overlying polymer coating to improve the adhesive strength of the polymer coating to the fiber.

  • Patent number: 8932670
    Abstract: A method of making a glass article with an anti-smudge surface includes providing a glass article with a target surface. The method includes providing a coating solution consisting essentially of a fluorosilane compound and a solvent that is miscible with the fluorosilane compound. The method includes spray-coating the target surface with the coating solution while controlling the spray-coating to form a coating layer having a thickness in a range from 1 to 20 nm on the target surface.
