A dye-exchanged zeolite marker wherein the zeolite is characterized by a pores size comprised between 4 and 12 and the dye is an organic cationic molecule, characterized by an amount of dye comprised between 0.05% wt and 1% wt with respect to the zeolite weight, optically active compositions comprising the same dispersed in a polymeric matrix and their use as a detectable marker.

A rolling bearing includes an outer ring having an outer surface configured to be fitted into a first component, an inner ring having an inner surface configured to be fitted onto a second component, at least one rolling element arranged between the outer ring and the inner ring, and an antimony-free composite coating on the outer surface of the outer ring and/or the inner surface of the inner ring. The antimony-free composite comprises a binder and polytetrafluorethylene as a solid lubricant.

A coating composition, a preparation method therefor and use thereof are provided. The coating composition includes at least 60% heat-expandable microspheres having a wall thickness of less than or equal to 5 m, a water-based thermoplastic resin, a water-based thermosetting resin, and a hot-melt filling resin. Thin-shell spheres can be quickly softened and ruptured within a short time in the heat-expansion process, and with the volatilization of an organic solvent, the coating composition cross-links with a resin matrix in the coating to form a cross-linked network structure, thus strengthening the gap support of the coating, and enabling the coating to achieve stepped expansion. After expansion, some polymer materials wrap an airbag and harden to form a stable hollow structure. Therefore, the expanded coating can be used for the fixation of high temperature-resistant parts, and can maintain adhesive stability when placed in a high-temperature environment (140-180 C.) for a long time.

A compound for coating a steel pipe includes a resin compound including a silicone resin and a ceramic compound. The resin compound makes up about 60%-70% of the compound for coating a pipe by weight, and the ceramic compound makes up between about 30%-40% of the compound for coating a pipe by weight. The resin compound comprises about 60%-70% acrylic resin by weight, and about 30%-40% of a silicone hybrid resin compound by weight; or about 90% silicone resin by weight, and about 10% by weight of a mixture of sodium dissolved in water. The ceramic compound comprises a mixture of ceramic hollow sphere, mica and perlite. The compound for coating a pipe can be applied directly to an exterior surface of a steel pipe while the pipe is heated to a temperature ranging from at or below 32 F. to about 400 F., or about 400F.-800F., or about 800F.-1,200F.

An anti-glare film is disclosed, which comprises a recycled polyethylene terephthalate substrate and an anti-glare coating layer on the recycled PET (rPET) substrate. The recycled PET substrate contains at least 50% recycled PET resin, and the anti-glare coating layer includes an acrylate binder resin and a plurality of amorphous inorganic microparticles. The disclosed anti-glare film has a concave-convex surface formed on the surface of the anti-glare coating layer by the amorphous inorganic microparticles to effectively mask impurity particles and/or microbubbles in the recycled PET substrate for being used in display devices.

An aqueous coating composition comprising (a) from 12.5% to 87% by weight based on the weight of the aqueous coating composition, of a film-forming polymer; (b) from 9.5% to 85% by weight based on the weight of the film-forming polymer, of a specific oligomer; and (c) from 2.5% to 50% by weight based on the weight of the film-forming polymer, of beads with a mean particle size of from 5.0 to 10.5 m; and a process for preparing the aqueous coating composition.

A rolling bearing includes an outer ring having an outer surface configured to be fitted into a first component, an inner ring having an inner surface configured to be fitted onto a second component, at least one rolling element arranged between the outer ring and the inner ring, and an antimony-free composite coating comprising a binder and a solid lubricant on the outer surface of the outer ring and/or the inner surface of the inner ring.

A conductive paste, a manufacturing method of a conductive paste, a capacitor element and a manufacturing method of a capacitor element are provided. The conductive paste includes a conductive composite material powder and a resin. The conductive composite material powder is obtained by grinding a conductive composite material in a solid state. The resin is mixed with the conductive composite material powder.

A treated zinc pigment that provides cathodic corrosion protection in aqueous zinc-rich coatings is described. The treated zinc pigment shows reduced gas generation in aqueous formulation.

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a polymer matrix comprising a first polymer material and a second polymer material that are immiscible with each other, and a plurality of piezoelectric particles substantially localized in one of the first polymer material or the second polymer material. The piezoelectric particles may remain substantially non-agglomerated when combined with the polymer matrix. The compositions may define a form factor such as a composite filament, a composite pellet, or an extrudable composite paste. Additive manufacturing processes using the compositions may comprise forming a printed part by depositing the compositions layer-by-layer.
