The present invention relates to a boron nitride (BN(C)) composite material in the form of a continuous structure, and a phase change material (PCM) included inside said continuous structure of (BN(C)), the method for manufacturing same and the components that comprise same.

Compositions, methods, and products that improve the adhesion of markings, for example, thermoplastic road markings, to substrates are disclosed. In some embodiments, such thermoplastic road markings include, but are not limited to, striping, solid lines, broken lines, and other traffic safety or informative markings placed on a substrate.

A 100% solids composition and method for priming or sealing a concrete surface wherein the 100% solids composition is formed of a tree rosin ester resin and a vegetable oil or vegetable oil-derived plasticizer, which are renewable or largely renewable, and wherein the 100% solids composition provides strong adhesion, can be applied by brushing or spraying at a temperature of less than 400? F. without adding a solvent or water thereto, produces substantially no VOCs, requires no time for curing or evaporation, and is ready for traffic or other normal use after cooling.

A process for manufacturing a part made of a ceramic matrix composite material, includes coating an outer surface of a porous preform with a layer of a fugitive material to form a model of the part to be obtained, the fugitive material being wax or resin, the fugitive material layer in the model not exceeding the highest peak of surface undulations of the preform, and ceramic and/or carbon particles being present in the porosity of the preform, coating the model formed with a ceramic powder composition, heat treating the coated model to remove the fugitive material and form a ceramic shell mold by sintering of the ceramic powder composition, introducing a molten composition including silicon into the shell mold to obtain the part in the shell mold, the molten composition infiltrating the porosity of the preform to form the ceramic matrix, and separating the shell mold from the part obtained.

A composition that may be used to retain moisture within fresh concrete as it cures to optimize the curing of the concrete may include one or more hardening and densifying agents (e.g., alkali metal polysilicate, colloidal silica, etc.) and one or more temporary moisture sealing agents (e.g., a wax, etc.). Additionally, such a composition may include a siliconate (e.g., a metal siliconate, such as an alkali metal siliconate like potassium methyl siliconate, etc.). The hardening and densifying agent of such a composition may penetrate the surface of fresh concrete to react with free lime, providing the fresh concrete with a strong surface. The temporary moisture sealing agent may form a moisture barrier on the surface of the fresh concrete to prevent moisture from escaping from the fresh concrete (e.g., evaporating, etc.) before the fresh concrete has sufficiently cured. The temporary moisture sealing agent may degrade within a matter of days (e.g., three days, seven days, 14 days, less than a month, etc.), facilitating its removal from the surface of the concrete once the concrete has cured and enabling further treatment of the surface without undue delay.
