A restoration system which is used to restore brick, glass, concrete, metal, plexiglass, and stone to their original color and preserve the materials. The restoration system includes a treatment composition overlay including a first-dry-part, a second-dry-part, a first-liquid-part, and a second-liquid-part. The first-dry-part is an acrylic based dry polymer. The second-dry-part is an acrylic based dry hardener. The first-liquid-part includes polymeric resin, water, acrylic polymer, and sodium. The second-liquid-part includes acrylic resin, water acrylic polymer, aqueous ammonia, and additives. The first-dry-part, the second-dry-part, the first-liquid-part, and the second-liquid-part are configured to be mixed to create a treatment composition overlay for restoring and preserving at least one surface.

Disclosed is a product comprised of a urethane reducer and an oil.

The present invention provides an oxidative polymerization resin-based composite coating film capable of being renewed a number of times by peeling a coating-film surface layer. More specifically, a coating composition comprising a base resin composition containing an oxidative polymerization resin; an organic compound having a melting point of 5 to 150 C.; a dryer; and an oxidative polymerization inhibitor containing at least one of a dryer protectant and a radical inhibitor is used to form a composite coating film made up of a cured film layer and an uncured inner layer.

Systems and methods for safely repairing potable water tanks when submerged within a tank. The barrier may be shield structure defining a cavity and having an aperture and valve for injecting the coating material into the cavity, or the barrier may be a sheet preloaded with coating material and stored within and delivered via a transfer shield, or the barrier may be a continuous sheet delivered over the top of the coating material at the same time it is applied. The barrier layer, be it a shield structure sheet or continuous sheet, becomes adhered to the substrate being repaired so post cure removal is not required. Methods of repair include pressing the sealing edge of a barrier shield over an area, injecting coating material between the barrier shield and area, removing the source of coating material, and permitting the coating material to cure.

A method for inspecting a gas turbine engine using a maintenance tool includes assembling a plurality of rail segments of a rail system of the maintenance tool within a core air flowpath of the gas turbine engine. The gas turbine engine includes a compressor section, a combustion section, and a turbine section together defining at least in part the core air flowpath. The method also includes moving a maintenance head of the maintenance tool along the plurality of rail segments of the rail system to perform maintenance operations within the core air flowpath of the gas turbine engine.

Systems and methods that provide or restore a coating to a component are provided. The systems and methods utilized an atomizing spray device. A slurry that comprises a fluid and ceramic particles, and a gas are supplied to the atomizing spray device. The slurry and gas are discharged from the spray device to form two-phase droplets. The fluid within the droplets evaporates to prevent the fluid from becoming part of the coating as the droplets traverse through the air and prior to impacting the surface of the component.

A method for surface writing is disclosed. The method includes fabricating a plurality of nanomotors, forming a secondary solution by adding the plurality of nanomotors to a primary solution placed on a substrate, guiding the plurality of nanomotors along a path in the secondary solution, and forming a sol-gel film along the path on a surface of the substrate. Wherein, the primary solution includes a monomer and hydrogen peroxide (H.sub.2O.sub.2). Fabricating the plurality of nanomotors includes preparing a mesoporous silica template, forming the plurality of nanomotors within the mesoporous silica template, and separating the plurality of nanomotors from the mesoporous silica template. The mesoporous silica template includes a plurality of channels, wherein each channel of the plurality of channels has a diameter less than about 50 nm and a length of less than about 100 nm, and each nanomotor of the plurality of nanomotors is formed within a channel of the plurality of channels.

Methods, compositions and systems for prolonging the lives of transportation surfaces, including pavement, runways, bridges and parking structures include physically altering the transportation surface and chemically protecting the transportation surfaces. Physical alteration of a transportation surface may include physically altering one or both of a microtexture and a macrotexture of the transportation surface. Chemical protection of a transportation surface may include hardening and/or densifying the transportation surface. The transportation surface may be chemically protected while physically altering the transportation surface or after the transportation surface has been physically altered.

Provided are a color-matching apparatus and a color-matching method for a repair paint capable of sufficiently supporting a color-matching operation that has been conventionally performed by experience and intuition, mainly at an automobile repair shop. The color-matching apparatus and the color-matching method for a repair paint calculates, for each coordinate axis, an error between colorimetric data of a painting object portion and colorimetric data of a painting plate (S3), retrieves, for each coordinate axis, a mixed paint having characteristic information acting in a direction of reducing the error as a color-matching candidate (S5), calculate a basic amount of the color-matching candidate corresponding to an amount of the repair paint used for painting the painting object portion (S7), calculate, for each coordinate axis, an error rate by dividing the error by a reference value corresponding to the colorimetric data (S8), and calculate a color-matching amount for each color-matching candidate by multiplying the basic amount of the color-matching candidate by the error rate (S10).

Applicant discloses a novel method of spray applying multiple courses of a rapid cure, two part polymer sealant to an aircraft surface. The method sometimes uses a two part polymer mix for use in the aircraft industry that is applied with pneumatic mix and spray gun. The two part cartridge is used in the mix and spray gun so the mix is applied immediately upon mixing, but the two components are kept separated unless the gun is applying the mix. The multiple courses cure to form a clear sealant that allows for inspection of cracks and corrosion beneath the sealant. It cures quickly so that the coated part may be further processed, for example in the assembly line during aircraft build. Applicant further discloses multiple spray gun systems for applying such a two-part polymer mix to aircraft parts.
