A tire dressing is provided with a fine polymer-based reflective particles formed form of a blend of anisotropic particles of varying color that introduce an added reflective surface not present in ordinary tire dressings. The use of the fine polymer-based reflective particles enhance gloss, shine, and light reflectivity to the applied surface. The enhanced reflective surface effect is more noticeable during vehicle motion and the tire is rotating, as light is reflected from different reflective particles due to the changing angle of the particles caused by the rotation of the tire. The effects are more subtle than the typical effect of glitter due to the small particle size and the utilization of a mixtures of several types of polymer reflective particles that range from dark to bright and vary in color, and the presence of the high refractive index liquid silicone fluid that results in a brilliant radiant shine.

In one aspect, a cohesive product comprises a substrate and a cohesive layer provided on at least one surface of the substrate. The cohesive layer comprises a cohesive composition including a cohesive component admixed with a glitter component. The cohesive component further comprising a thickening agent in an amount sufficient to maintain the glitter component substantially uniformly distributed in the cohesive composition. In a further aspect, a method of manufacturing a cohesive produce is provided.

An antireflection coating film for an optical element is provided on a surface of a substrate of an optical material and includes first particles having a refractive index (nd) of at least 2.2 or more for the d-line and an average particle size of 10 to 70 nm, second particles of at least one of silica and sericite and having an average particle size of 1 to 11 μm, a colorant of an organic substance and soluble in an organic solvent, and a resin, in which the first particle content is in the range of 10% to 35% by weight, and second particle content is in the range of 1% to 11% by weight. The antireflection coating film has a high effect of preventing surface reflection, a high effect of preventing inner-surface reflection, satisfactory absorption of visible light, and low levels of reflection and scattering in the film.

A piezoelectric capacitor includes A) a composite article that has 1) a dry piezoelectric layer (dry PL); 2) a first dry electrode comprising a dry electrically-conductive layer arranged contiguously with a first opposing surface of the dry PL; and 3) a second dry electrode arranged contiguously with a second opposing surface of the dry PL. The dry electrically-conductive layer has essentially (a) an electrically-conductive material; and (b) particles having a Young's modulus that is different from the Young's modulus of the (a) electrically-conductive material by at least 10%. The capacitor also has B) electrical communication means attached to both electrodes for electrical communication of the composite article with an external electrical circuit.

A fast drying, heavy metal-free, high performance coating composition with outstanding UV resistance, and excellent corrosion resistance coupled with fast dry and long pot life. This coating can be applied over DTM, such as blasted cold rolled steel, or treated cold rolled steel, aluminum and treated aluminum. High corrosion resistance without sacrificing gloss or UV resistance achieved by selecting proper pigments and proper pigment design and packing by advantageously utilizing differing pigment morphologies (sizes and shape).

A housing for repeater having an accommodation part accommodating therein a device for repeating an RF signal, and at least a portion of the housing is implemented with heat dissipation plastic having, at a frequency of 28 GHz, a relative permittivity of less than or equal to 4 and a thermal conductivity of greater than or equal to 3 W/mK. Accordingly, as the housing has a high heat dissipation performance against high heat generated from various types of devices provided inside the repeater for transmitting and receiving a signal in a high frequency band and minimizes the interference of transmission and reception of the signal in the high frequency band, the housing can be widely used as a housing for repeater in the mobile communication field or the like using a signal in a high frequency band.
