A method and coating are provided for temporarily protecting a substrate or article during shipping, handling or storage by applying a removable protective coating over at least a portion of the substrate. The substrate may be flat or curved and may have zero, one or more functional coatings. A plurality of substrates with the protective coating of the invention may be arranged in a shipping container so that the protective coating reduces the possibility of damage to the substrate or optional functional coating. In one embodiment, the protective coating is the evaporation or reaction product of an aqueous coating composition containing a polyvinyl alcohol polymer which may be subsequently removed by aqueous washing, thermal decomposition or combustion. In another embodiment, the protective coating is formed by sputtering a substantially carbon coating onto the substrate. The carbon coating is subsequently removed by combustion. The protective coating may have identification materials, such as colorants or fragrance materials, such that different types of substrates and/or functional coatings can be distinguished from each other. Additionally, the temporary protective coating can improve the heating of a functionally coated glass substrate.

The segmented porous fibrous substrate disclosed can be fabricated from a variety of materials to provide for effective filtration and as a catalytic host in various applications, including exhaust filtration of internal combustion engines.

A method of repairing a turbine engine airfoil part includes the step of first determining dimensional differences between pre-repaired dimensions of a turbine engine airfoil part and desired post-repair dimensions of the turbine engine airfoil part. The turbine engine airfoil part has a metal alloy substrate. A build-up thickness is determined of coating material that is required to obtain the desired post-repair dimensions of the airfoil part. A high-density coating process is performed to coat the turbine engine airfoil part substrate with a coating material to build-up a thickness of coating material effective to obtain desired finished dimensions after performing a hot isostatic pressing treatment. The high density coating process comprises the steps of accelerating metal particles in an inert carrier gas, and directing the accelerated metal particles onto the turbine engine airfoil part so that high-speed collision of the metal particles causes deformation of the particles resulting in a large increase in the surface area of the particles producing the controlled buildup of a high density coating of the deformed metal particles. The hot isostatic pressing treatment is performed to obtain a post-repair turbine engine airfoil part having the desired post-repair dimensions and having diffusion bonding between the coating material and the turbine engine airfoil substrate.

The present invention is directed to a method for producing a high gloss coating on a printed surface. In the present method, an aqueous coating composition is deposited onto a surface to be printed using a blanket roller coating face which is a low energy, non-stick, smooth surface profile. In the present method, simultaneous with the deposition of aqueous coating onto a substrate, or shortly thereafter, pressure either alone or in combination with heat may be applied to the coating in order to create a substantially tack-free surface conforming to the surface of the coating face. By using a highly polished coating face, high gloss coatings may be readily obtained using this methodology in a number of traditional printing techniques including wet trap inline sheet-fed printing, heat-set offset printing, dry trap inline flexographic printing, offset web-fed printing and gravure printing. Coatings which are produced utilizing the present invention have high gloss values heretofore unobtainable using aqueous coating compositions.
