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.

Disclosed herein are floor tiles comprising, for instance, a substrate and a surface coating provided on an upper surface of the substrate, wherein the surface coating comprises (i) a base formula comprising a glaze and (ii) solid particles comprising tabular alumina.

A flame or heat flux protective coating composition, which includes a dispersion of fiberglass, hollow glass spheres, or a combination of both in silicone. A flame or heat flux protective sheet, which includes hollow glass spheres dispersed in silicone in a sheet form or fiberglass and silicone in a sheet form, wherein the fiberglass is dispersed in the silicone or the fiberglass is a woven cloth coated with the silicone is also presented. Articles incorporating the flame or heat flux protective coating or sheet form and methods for coating an article with the flame or heat flux protective coating composition are also presented.

A chamber component comprises a body and a plasma sprayed ceramic coating on the body. The plasma sprayed ceramic coating is applied using a method that includes feeding powder comprising a yttrium oxide containing solid solution into a plasma spraying system, wherein the powder comprises a majority of donut-shaped particles, each of the donut-shaped particles having a spherical body with indentations on opposite sides of the spherical body. The method further includes plasma spray coating the body to apply a ceramic coating onto the body, wherein the ceramic coating comprises the yttrium oxide containing solid solution, wherein the donut-shaped particles cause the ceramic coating to have an improved morphology and a decreased porosity as compared to powder particles of other shapes, wherein the improved surface morphology comprises a reduced amount of surface nodules.

A piece, in particular for jewellery or timepieces, is made of a material comprising a synthetic matrix loaded with particles of a precious or semi-precious stone. The particles have a particle size d90 between 50 μm and 2 mm, preferably between 100 μm and 1 mm, and more preferably between 150 μm and 500 μm.

Scanning Probe Microscope (SPM) system configured with the use of a composite material employing a non-metallic matrix and at least one of diamond particles, fused silica particles, boron carbide particles, silicon carbide particles, aluminum oxide particles, carbon fiber elements, carbon nanotube elements, and doped diamond particles to increase the structural integrity and/or strength of the SPM system, and a fraction of reinforcement ranging from at least 25% to at least 75% with advantageous modification of the Young's modulus, coefficient of thermal expansion, and thermal conductivity.

The invention relates to multilayer structures made of at least one thermoplastic material and having at least one metal layer. The invention further relates to multilayer products encompassing at least three layers comprising a substrate layer made of a substrate comprising specific copolycarbonates and at least one inorganic filler, a metal layer and one or more further layers. The invention further relates to the process for producing the said multilayer structures.

Provided is a circuit substrate, including a glass film (10) forming a rough layer (11) after surface roughness processing, a resin adhesion (20) located the rough layer (11) on either side of the glass film (10), and a metal foil (30) located on the outside of resin adhesion layer (20). The glass film (10), the resin adhesion layer (20) and the metal foil (30) are joined together through suppressing. The circuit substrate employs the glass film (10) which forms a rough layer (11) after surface roughness processing as a carrier material, so that the resin adhesion layer (20) and the surface of the glass film (10) have a good binding force, and the dielectric constant of the circuit substrate has slight difference in the directions of X, Y and Z. Also provided is manufacturing method for a circuit substrate.

A reactive pressure sensitive adhesive composition is disclosed. A tape formed using the reactive pressure sensitive adhesive is also disclosed. In its cured state, the pressure sensitive adhesive shows superior mechanical and electrical properties compared to conventional, non-curable charge collection tapes. The tape has a cure profile pre-selected to correspond to that of a photovoltaic cell fabrication process, such that curing can take place during cell fabrication and may occur simultaneously with one or more other curing steps employed in cell fabrication.

The disclosed retroreflective element includes a polymeric core that is loaded with a plurality of first beads and second beads distributed at the perimeter of the core. The first beads are different than the second beads. Because of the beads in the core, the retroreflective element remains useful for returning light even after portions of the core begins to wear away. Further, when the retroreflective elements get wet, water will settle to the bottom of the perimeter of the core. Therefore, using the second beads with a refractive index suited for wet conditions, while the first beads have a refractive index suited for dry conditions allows the retroreflective element to be useful in both wet and dry conditions even while the retroreflective element wears during use.
