A utility or marine pole comprises a honeycomb core having an outer surface and a rubber coating on substantially all of the outer surface of the core. The core has a length of from about 12 feet to about 30 feet and a circumference of from about 5 inches to about 15 inches. A bracket for a pole used for supporting wires, the bracket comprising a body being circular in horizontal cross section, means for adjusting the diameter of the body, and a lateral extension having a first end portion supported by the body and an opposed second end portion, wherein the second end portion has an opening for receiving a wire. A railroad crossing section comprising a honeycomb core has a circumferential outer surface and being rectangular in vertical cross section and a rubber coating on substantially all of the outer surface of the core.

A coating film capable of being peeled off in the shape of sheet to facilitate a coating film removal work, and is less likely to peel even after long periods of use on an underwater structure is provided. The coating film comprises an undercoat layer to be bonded to an underwater structure, and an antifouling layer bonded to the undercoat layer, wherein: a 100-gram underwater constant load peeling degree of the coating film is less than 5; a ratio of a tensile breaking strength of the coating film to an adhesive force of the coating film with respect to the underwater structure, as measured after immersing the coating film in pure water at 60° C. for 5 weeks is 1.5 or more; and a 1-mm square cross-cut stretching-caused peeling degree of the antifouling layer with respect to the undercoat layer is 0.05 or less.

The present disclosure relates to a coating solution composition for a 3D model, that includes a rubber material and an organic solvent, a preparation method thereof, and a preparation method of a 3D model using the same. When a 3D model is coated using the coating solution composition for a 3D model of the present disclosure, the coated 3D model will have a similar elasticity and strength as those of an organ, thus enabling surgical simulation, and therefore, it can be used in surgeries that require surgical simulation due to the small size of pediatric hearts and the like and variety and complexity of related diseases, thereby inducing successful surgeries, and thus it can be widely used in the medical industry.

Disclosed are a method for manufacturing a dissolvable slip and a dissolvable slip manufactured by same. The manufacturing method sequentially comprises the following steps: (1) mixing an adhesive with solid particles and dissolvable particles; (2) coating the mixture prepared in step (1) on the surface of a slip body; and (3) curing the mixture coated in step (2). The dissolvable slip manufactured according to the manufacturing method not only has a stronger anchoring force with a wellbore inner wall, but also can adjust the dissolution rate of the slip after the completion of fracturing to enable the slip to degrade within a preset time. Further, the dissolvable slip has a better abrasion resistance, is suitable for various temperature conditions, and can still work normally in a concentrated acid or a concentrated alkali environment.

Methods utilizing a rubber coating developed from chemical devulcanization are disclosed herein. One method includes chemically devulcanizing rubber to create liquid rubber, placing the liquid rubber into a mold configured to form a liner for use with a casket, and drying the liquid rubber to form the liner, which lines an interior of the casket. Another method includes chemically devulcanizing rubber into liquid rubber, placing the liquid rubber into a pressurized spray container, forming a liquid rubber coating spray by preserving the liquid rubber within the spray container, spraying the liquid rubber onto a surface, and drying the liquid rubber to solidify it over the surface. An alternative method includes chemically devulcanizing rubber into liquid rubber, mixing the liquid rubber with asphalt to form a liquid rubber-asphalt mixture, paving a surface with the liquid rubber-asphalt mixture, and drying the liquid rubber-asphalt mixture to solidify it over the surface.
