A long-acting super-hydrophobic coating resistant to water pressure impact and preparation method thereof. The long-acting super-hydrophobic coating includes a conductive substrate and the following raw materials in parts by weight: 1 part to 10 parts of titanium source or zinc source, 40 parts to 100 parts of deionized water, 20 parts to 50 parts of hydrochloric acid or 20 parts to 40 parts of sodium hydroxide, 1 part to 10 parts of electrolyte, 1 part to 10 parts of low surface energy modifier, 10 parts to 20 parts of high molecular polymer, 1 part to 5 parts of carbon nanotube and 70 parts to 100 parts of organic solvent. The long-acting super-hydrophobic coating has an organic-inorganic nano-interpenetrating network structure, which improves the stability of the multi-stage nano-micro structure, so that the super-hydrophobic coating surface has a good high-pressure water impact resistance and high-pressure static water resistance.

The present disclosure is directed to a curable precursor of a pressure sensitive adhesive comprising a) a (co)polymeric material comprising a rubber-based elastomeric material; b) a polyfunctional aziridine curing agent; and c) an acid generating agent. The present disclosure is also directed to a method of manufacturing such pressure sensitive adhesives and uses thereof.

Embodiments provide a polishing composition for a magnetic disk substrate containing colloidal silica, a water-soluble polymer, and water. The water-soluble polymer compound is a copolymer containing a monomer having a carboxylic acid group, a monomer having an amide group, and a monomer having a sulfonic acid group as essential monomers. The water-soluble polymer compound has a weight average molecular weight of 1,000 to 1,000,000.

Process for producing an aqueous binder comprising at least one polycarboxylic acid, at least one compound having at least two hydroxyl groups, and at least one phosphorus compound.

A double coating, curing method, cured coating, and kit are provided. A first layer of the double coating can be a first cure coating composition, which has a first hydroxy-functional resin, a first crosslinking agent, and a first catalyst. A second layer of a second cure coating composition can have a low hydrophilicity acrylic resin as a second hydroxy-functional resin, a second crosslinking agent, and a second catalyst. The first catalyst catalyzes crosslinking between the second hydroxy-functional resin and crosslinking agent, and not between the first hydroxy-functional resin and crosslinking agent. The second catalyst catalyzes crosslinking between the first hydroxy-functional resin and crosslinking agent, and not between the second hydroxy-functional resin and crosslinking agent. The first and/or second hydroxy functional resins can facilitate catalyst migration from one layer to the other. The separate compositions can be shelf-stable and/or the curing can occur at low temperature.

A copolyester film comprising a copolyester which comprises repeating units derived from a diol, a dicarboxylic acid and a poly(alkylene oxide), wherein the copolyester film further comprises a first metal ion-containing component selected from conductive ceramic particulate materials, and wherein the film may further comprise additional metal ions from one or more sources other than said conductive ceramic particulate material.
