摘要:
Fluorocarbon- and urethane-(meth)acryl-containing additives and hardcoats. The hardcoats are particularly useful as a surface layer on an optical device.
摘要:
Polypropylene fibers and devices that include a fatty acid monoglyceride added to the polypropylene as a melt additive are described. A hydrophilic enhancer material can be advantageously added to the polypropylene as a melt additive to enhance the hydrophilicity of the fibers and devices. An antimicrobial enhancer material can be added to the fibers to enhance the antimicrobial activity.
摘要:
Fluorochemical silane compounds and coating compositions derived therefrom are described. The compounds and compositions may be used in treating substrates, in particular substrates having a hard surface such as ceramics or glass, to render them water, oil, stain, and soil repellent.

摘要:
A low refractive index composition that forms a low refractive index layer on an optical display is formed having a co-crosslinked interpenetrating polymer network of a fluoropolymer phase and an acrylate phase. The fluoropolymer phase is preferably formed from fluoropolymers based on THV or FKM and having either a degree of unsaturation and/or containing a reactive cure site monomer in its polymer backbone. The acrylate phase includes a multifunctional acrylate crosslinker, and more preferably includes a perfluoropolyether acrylate crosslinker. The formed low refractive index layer has improved interfacial adhesion to other layers or substrates contained in the optical display. Further, the mechanical strength and scratch resistance of the either of above low refractive index compositions can be further enhanced through the incorporation of surface functionalized inorganic particle into the formed layer.
摘要:
An article is provided that includes a mold comprising a pattern, a metal-containing layer in contact with the pattern, and a release agent that includes a functionalized perfluoropolyether bonded to the metal-containing layer. Also provided is a method of replication that includes the mold.
摘要:
An economic, optically transmissive, stain and ink repellent, durable low refractive index fluoropolymer composition for use in an antireflection film or coupled to an optical display. In one aspect of the invention, the composition is formed from the reaction product of a fluoropolymer or reactive fluoropolymer, an amino silane ester coupling agent or ester equivalent, a multi-olefinic crosslinker, and optional surface modified inorganic particles or sol gel precursors.
摘要:
Fiber, fabric, film, molded or blown article comprising a water- and oil-repellent composition comprising a melt blend of components (a) and (b) in which: (a) comprises a repellency-imparting, fluorochemical composition comprising at least one fluorine-containing aromatic ester oligomer comprising (1) at least two repeat units derived or derivable from the reaction of at least one dicarboxylic acid (or a derivative thereof) and at least one polyol, with the proviso that either the dicarboxylic acid (or derivative) or the polyol (or both) is aromatic or heteroaromatic, and (2) fluorochemical endgroups derived or derivable from the reaction of (i) the dicarboxylic acid (or derivative) and at least one fluorine-containing monoalcohol, or (ii) the polyol and at least one fluorine-containing monocarboxylic acid; and (b) comprises a treatable substrate material; with the proviso that, when the treatable substrate material comprises a mixture of at least two polymers, the mixture is non-stratifying.
