A pouch-type secondary battery and a method of manufacturing same are capable of completely protecting a metal layer from moisture or air by forming an insulating coating layer including a conformal coating layer on the metal layer exposed at a cut surface of a battery case. The method includes a first step of preparing a battery case including an upper case and a lower case by cutting a laminate sheet including an outer coating layer, a metal layer, and an inner coating layer; a second step of receiving an electrode assembly between the upper case and the lower case; a third step of forming a sealing portion by contacting outer peripheries of the upper case and the lower case; and a fourth step of forming a conformal coating layer on a side surface of the sealing portion so as to prevent exposure of the metal layer.

A method of treating a surface of wood products to inhibit the uptake of moisture into the wood by providing an aqueous formulation comprising polyethylene-vinyl acetate in water, 2-99 percent polyethylene-vinyl acetate by weight. The aqueous formulation is applied to the surface of wood products, wherein the wood products remain outdoors or in a damp environment having 60% or greater relative humidity. The aqueous formulation is allowed to dry and form a micro-film on the surface of the wood products. The moisture content in the wood products is maintained at 16 percent or less. A pesticide effect on the surface of the wood products is produced, inhibiting infestation of the wood products by insects.

A repair solution for a wind turbine blade is described. The repair solution includes the application of a layer of viscous coating material to the section of the blade to be repaired, which is cured to form a repaired surface. The layer of viscous coating material may be temporarily covered during the curing process using a film of Low Surface Energy material, to prevent defects in the repaired surface from dust, insects, etc. Additionally or alternatively, a temporary shield may be erected adjacent the curing layer of coating material, to allow for the control of the temperature and/or humidity levels of the region adjacent the curing material, to provide for more effective control of the curing process and to allow for repairs to be carried out for a wider process window.

A coating composition for applying a very thin film coating to a substrate such as a polymeric film comprises a copolymer such as a block copolymer (BCP) that is compatible with the substrate, an alcohol solvent or solvents capable of dissolving the copolymer, a hydrolysed metal alkoxide precursor, a carboxylic acid stabiliser, and an active agent in an ionic, molecular, or small nanoparticle form. The active agent is configured to provide a functionality to the coating composition, selected from antimicrobial, antifungal, barrier, therapeutic, electrical, electronic, magnetic and optical. The composition is a sol comprising a continuous non-sedimentable/stable suspension of very small sized (of nano order) amorphous inorganic polymers in their oligomeric or polymeric state, and comprising the active agent dispersed in a hydrolysed metal alkoxide-BCP matrix. Substrates coated with very thin coatings are also provided, including coated LDPE which is activated before coating by UV/ozone, plasma or corona treatment prior to deposition of a wetting layer.

A resin applied to underwater structures to enable biofouling growing thereon to be removed therefrom much easier than biofouling growing directly on the underwater structure. Adding antifungal properties to the resin enables the resin to prevent, or limit, the growth of biofouling thereon. The antifungal properties are provided by at least some subset of antifungal agents (e.g., copper) and antimicrobial agents (e.g., silver). The agents are mixed with plastic (e.g., polyethylene), melted, extruded into a solid form and then processed into an antifouling resin where the antifouling agent is embedded and integrated in the resin prior to application. The antifouling resin presents its antifouling properties immediately upon application and does not require gradual degradation to expose the active antifouling agents. The antifouling resin is thermal sprayed onto the underwater structure (an initial layer may be thermal sprayed onto an epoxy layer prior to curing to merge the two layers).

A lubricating film-coated steel sheet has at least one surface on which an organic resin film is formed. The organic resin film contains an acrylic resin having a glass transition point (Tg) of 100 C. or higher and an acid value ratio R=acid value (mg-KOH/g)/Tg ( C.) of 1.50 or more, and 5 mass % or more of a polyolefin wax having a melting point of 100 C. or higher and 145 C. or lower and an average particle diameter of 3.0 m or less, and is formed on a surface of a steel sheet at a coating weight, W, of 0.3 g/m.sup.2 or more and 2.5 g/m.sup.2 or less per surface.
