A method of making a thermal control coating is provided. A primer layer can be applied to a substrate to form an exposed surface. The primer layer can include an epoxy binder and a silica filler. The exposed surface can be treated with an oxygen plasma to form a treated surface. A silicate-based thermal control coating can be applied to the treated surface, for example, by spraying, to form a thermal control coating on the substrate. Spacecraft and spacecraft hardware components coated with the thermal control coating, are also provided.

The disclosure relates to a self-healing laminate composition. The composition includes a first, self-healing layer with a self-healing polymer and a second, mechanical layer adjacent to the first layer. The second layer includes any desired polymer, for example a crosslinked polymer, a thermoplastic polymer, or a functional thermoset polymer. Self-healing polymers with dynamic covalent bonds are suitable, for example those with dynamic urea bonds and/or dynamic urethane bonds. A self-healing polymer that is damaged can undergo autonomous repair when separated surfaces re-contact each other due to the soft nature of the self-healing polymer, whereupon reversible bonds can reform to rejoin and repair the damaged self-healing polymer. When the self-healing laminate according to the disclosure is damaged, the self-healing mechanism of the first layer can cause the repair of both layers. The self-healing laminate composition can be used as a coating on any of a variety of substrates to provide self-healing properties to a surface

A protective coating method of a material such as aromatic polyurethane substrates is effected through a process that promotes coating adhesion to the substrate while providing a wood-like aesthetic. Closed cells on the surface of the aromatic polyurethane are opened via sanding techniques to promote adhesion. Once a sufficient surface is achieved, the substrate is coated using spray techniques to protect the aromatic polyurethane from ultra-violet light exposure. The wood-like appearance is achieved through embossing a wood-grain on the deformable surface and subsequently filling the grain with a contrasting agent to highlight its appearance through a reverse-roll-coating technique. Abrasion properties are achieved through a final clear top coat that allows both the contrast agent and the top coat to fully cure.

Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

A coating composition includes: (i) a film-forming resin; (ii) an infrared reflective pigment; and (iii) an infrared fluorescent pigment or dye different from the infrared reflective pigment. A multi-layer coating including the coating composition, and a substrate at least partially coated with the coating composition is also disclosed. A method of detecting an article at least partially coated with the coating composition is also disclosed.

A safety glove having a protective member or insert extending around the fingertip of the safety glove is provided. The protective member may be positioned along the outer surface or the inner surface of the glove. Alternatively, the protective member may be integrally formed between two layers of glove material. The protective member terminates distally from an interphalangeal joint line to enable finger flexion in order to grasp an item, such as a slab of meat to be deskinned in a skinning machine. The glove may include a rough outer surface formed from thrice dipping the glove and allowing the glove to cure. Additionally, the glove may have a width near the wrist that is wider than the width near the palm to enable the glove to be rapidly removed (i.e., doffed) in an emergency event of the glove getting caught in a rotating blade on the skinning machine.

A coating composition contains 25 to 35 parts by weight urethane synthetic resin solution, acrylic resin solution, or epoxy resin solution; 5 to 35 parts by weight urethane pigments, acrylic or epoxy pigments; 10 to 20 parts by weight PE-thermoplastic resin beads, phenol resin beads, melamine resin beads, epoxy resin beads, polystyrene resin beads or glass beads; 40 to 52 parts by weight organic solvents comprising urethane thinner and toluene; and 2 to 4 parts by weight curing agent, forms a coating sheet which can be attached to public or private installation, such as walls, poles, street lights, or traffic lights, to prevent adhesion of unlawful or unwanted materials on the installation, and can be provided with color tones same as those of the private or public installations in order not to defile the appearance of the street.

A method for manufacturing a photoacoustic ultrasound generator includes forming an uncured prepolymer polydimethylsiloxane (PDMS) film on a substrate, spraying a solution of light-absorbing nano-particles onto a surface of the uncured PDMS film, and then permeating and diffusing the light-absorbing nano-particles into the uncured PDMS film; and curing the uncured PDMS film containing the light-absorbing nano-particles distributed therein to form a composite film of nano-particles and PDMS.

The present invention relates to a material having various functions such as antimicrobial function or waterproof function, as well as a method and an apparatus for manufacturing the same. The method for manufacturing a functional material according to the present invention includes coating a surface of conductive or non-conductive material with an electrically charged microfine material having a size of nano- or micro-units, thereby imparting functionality to the material simultaneously with maintaining intrinsic properties thereof.

In addition, the method for manufacturing a functional material, according to the present invention, had advantages in which: repeating a process of coating the surface of the conductive or non-conductive material with a functional substance can impart a plurality of desired functions to the material, in addition, a thickness of the functional material may be easily adjusted, and a large area/large quantity may be produced by a simplified process using a general material in a short period.

A ceramic or composite coating is prepared from a mixture of a fire-resistant binder and an inorganic filler such that the mixture is suitable to be applied as a coating to a substrate, can be cured in situ, and protects the underlying substrate to which it is applied. In one example, the inorganic filler includes fly ash, where a mix ratio of the inorganic filler to the fire-resistant binder is from 1:1 to 9:1 by weight. The mixture can be cured in air at room temperature to form a composite coating on wood, metal, composites, and other substrates. High temperature processing can convert the composite to a ceramic.
