An erosion resistant article such as rotor blades for helicopters and wind turbines having the leading edge surface protected from damage from high speed impingement of rain or sand with a protective coating formed from specific polyurethane or polyurea coating having a defined set of minimum physical properties where the protective coating can be applied as a liquid coating and cured in place or as a preformed complementary shaped covering to protect the leading edge against erosion damage in service.

A method for treating a surface of flooring includes applying a composition that includes a silicate to a surface of the flooring and, while the composition is present on the surface, polishing or burnishing the surface. The silicate may be a lithium polysilicate and/or a colloidal silica. The composition may further include a surfactant and/or a leveling agent. When the composition is applied to the surface of the flooring, gravity may enable it to spread substantially evenly across the surface. The acts of applying and polishing or burnishing may be repeated. Such a treatment may result in a surface that has a glossiness of at least 80, as measured by a gloss meter set to a 60° angle of incidence.

A dielectric material is provided. The dielectric material includes at least one layer of a substantially continuous phase material. The material is selected from the group consisting of an organic, organometallic, or combination thereof in which the substantially continuous phase material has delocalized electrons.

Various tags and adhesive labels are described which can be used in high temperature environments such as up to 1,000° C. The tags and labels include a substrate having one or more high temperature printable coatings. The labels can also include pressure sensitive adhesives and optional release liners.

Provided is a spectacle lens having, on at least one side of a lens substrate, a polarizing layer containing a dichromic pigment, and a photochromic layer containing a photochromic pigment, and having the polarizing layer and the photochromic layer via an intermediate layer.

The invention relates to an item comprising a substrate having at least one main surface coated with a multilayer interferential coating comprising at least one layer with a refractive index higher than 1.65 and at least one layer with a refractive index lower than, or equal to, 1.65, at least one of the layers of the interferential coating being an organic-inorganic layer that has been deposited in a vacuum environment and has a thickness of at least 30 nm, said interferential coating having a thickness of at least 450 nm and/or at least 8 layers.

Light emitting devices and components having excellent chemical resistance and related methods are disclosed. In one embodiment, a component of a light emitting device can include a silver (Ag) portion, which can be silver on a substrate, and a protective layer disposed over the Ag portion. The protective layer can at least partially include an inorganic material for increasing the chemical resistance of the Ag portion.

A coating composition comprising a resin material comprising polyester imide polymer one or more titanate material; and one or more OH reactive cross linking material.

The invention relates to the use of a carbonaceous coating for protection of a passive electrical component from attack by ammonia, wherein the carbonaceous coating is a sol-gel coating or a plasma-polymeric coating. This coating comprises a particular carbon content.

The present invention relates to a low refractive layer and an anti-reflective film comprising the same. The low refractive layer can exhibit excellent optical properties such as a low reflectance and a high light transmittance, and excellent mechanical properties such as high wear resistance and scratch resistance at the same time. In particular, due to the excellent alkali resistance, the low refractive layer can maintain excellent physical properties even after alkali treatment. Therefore, when introducing a low refractive layer to the display device, it is expected that the production process can be simplified and further the production rate and the productivity can significantly increase.
