摘要:
A temperature-releasable coating is removed from a substrate by heating or cooling the non-SCC coating on the substrate until the temperature-releasable coating is at a release temperature, and disintegrating and loosening the coating while the coating is at the release temperature, to produce disintegrated coating particles that are loose on the substrate. A machine for removing a non-SCC temperature-releasable floor coating from a substrate comprises: means for heating or cooling the temperature-releasable floor coating to a release temperature, a solid contact agitator for disintegrating the floor coating and loosening the temperature-releasable floor coating while the floor coating is at the release temperature.

In various embodiments novel coatings for the protection of a paint booth are provided. In certain embodiments the coatings comprise a maltodextrin, a humectant; and pH adjuster. In certain embodiments the coatings can optionally additionally comprise a thickener, and/or a defoamer, and/or a surfactant and/or one or more preservatives. In certain embodiments the coating is a clear coating comprising a maltodextrin, a thickener ( e.g. , an xanthan gum thickener), a defoamer ( e.g. , a silicone defoamer), a surfactant ( e.g. , a nonionic surfactant such as an ethoxylated alcohol surfactant), a humectant ( e.g. , glycerine), a pH adjuster/humectant ( e.g. , triethanolamine), and one or more preservatives ( e.g. , of a combination of as 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-4-one (KATHON LX®), an aqueous dipropylene glycol solution of 1,2-benzisothiazolin-3-one (PROXEL GXL®), potassium metabisulfite, etc. ).
摘要:
A coating system for application to metal components prior to assembly or fabrication into large metal objects is described. The system includes a composition comprising a water- dispersible polymer component, a crosslinking agent, and a conductive material. When applied to a metal substrate, the coating system is weldable and provides optimal corrosion resistance during fabrication or assembly.

In order to provide an improved handling and preparation of metal sheets or strips, in particular allowing a more secure handling of the metal sheet or strip while achieving at the same time a less laborious and more accurate lubrication before forming of the metal sheet or strip, there is provided a coating of a metal sheet or strip comprising a lubricant and a protective base material, wherein the lubricant is contained in the protective base material and wherein the protective base material is at least in part selectively removable. There is also provided a metal sheet or strip capable of forming, in particular of superplastic forming, and having a coating according to the invention at least partially on one or on both sides of the metal sheet and a method for manufacturing a metal sheet or strip according to the invention comprising the steps of providing a metal sheet or strip capable of forming, in particular of superplastic forming, and applying a coating according to the invention.
摘要:
The present invention relates to the use of degradable coatings suitable for use on downhole tools. In particular, the present invention relates to pliable coatings for use on downhole tools that have been designed to be able to resist flaking or breaking off of the tool in response to a physical shock. Some embodiments of the present invention provide methods of reacting lactic acid, glycolic acid, or a combination thereof in a polymerization reaction to form a degradable polymer; combining the degradable polymer and a plasticizer to form a coating composition; applying the coating composition to a downhole tool; placing the coated downhole tool into a portion of a subterranean formation; and, hydrolyzing the degradable polymer of the coating composition to release an acid and degrade the coating.

An aqueous coating composition is provided, comprising a mixture of at least one polysaccharide or a derivative thereof in aqueous solution and a plurality of polysaccharide gel particles, said composition being capable of forming a film when applied onto a substrate. Also provided are methods and uses employing the aqueous coating composition for protecting a substrate from contamination and facilitating removal of contamination therefrom.
摘要:
The invention relates to a method for protecting a part of a surface of an aircraft against soiling with insect residues and/or against icing, comprising the following steps: a) coating the part of the surface to be protected with a coating, which can reduce the adhesion to the part of the surface to be protected down to removal within a period of time of = 3 hours from the start of the aircraft and under normal flight conditions on the basis of (i) temperature change and/or (ii) UV radiation and/or (iii) addition of a decomposing component and/or (iv) humidity difference, b) exposing the part of the surface to be protected to (i) a temperature change and/or (ii) UV irradiation and/or (iii) addition of a decomposing component and/or (iv) a humidity difference so that soiling and/or icing that may be present on the coating are removed therefrom.
摘要:
A composition utilized to prevent the deposit of overspray, the composition comprising, based on the total weight of the composition, (a) from about 1% to about 60% by weight a blend of dibasic esters; (b) from about 10% to about 75% by weight one or more surfactants; and (c) a thickener, and methods for use. The dibasic esters are be derived from a blend of adipic, glutaric, and succinic diacids, and, in one particular embodiment, the blend comprises dialkyl methylglutarate and at least one of dialkyl adipate and dialkyl ethylsuccinate, wherein the alkyl groups individually comprise a C1-Cj2 hydrocarbon group. The one or more surfactants are typically chosen from alcohol alkoxylate, an alkyl phenol ethoxylate, a terpene, a terpene alkoxylate or any derivates thereof. The thickener is typically one or a combination of polyacrylates, magnesium silicates, polyvinyl alcohol, fumed silicas, guar gum, guar gum derivatives, cellulose, and cellulose derivatives.
