  • Publication number: 20240132753
    Abstract: A hydrophobic-icephobic composition includes a monomer binder, an organic solvent, and a hydrolyzed organosilane. The hydrolyzed organosilane is represented by a formula of R1—Si—(OH)3. The R1 group comprises an alkyl or a haloalkyl having from 3 to 40 carbons. A hydrophobic-icephobic coating over a substrate includes a polymer base and a polyorganosiloxane. The polyorganosiloxane includes —(R1—Si—O2)- units. The R1 group includes an alkyl or a haloalkyl having from 3 to 40 carbons. One or more of the —(R1—Si—O2)- units of the polyorganosiloxane are may be chemically bonded to the substrate.

  • Publication number: 20210032477
    Abstract: In certain aspects, a composition includes a monomer binder, a plurality of silica nanoparticles, a surface energy reducing additive, and a blend of a high polarity solvent and a low polarity solvent. The high polarity solvent has a dipole moment of about 1.2 or greater, and the low polarity solvent has a dipole moment of about 0.7 or less. In certain aspects, a coated substrate includes a substrate and a coating over the substrate. The substrate is selected from a group consisting of glass, polycarbonate, polyacrylate, and polyethylene terepthalate. The coating includes a polymer binder, a plurality of nanoparticles, and a surface energy reducing additive. The coated substrate has a transparency of at least about 80% light transmission at one or more wavelengths in a range of 380 nm to 740 nm.
