The present invention relates to a new process for providing a coating layer on a moulded article comprising fibers. In the present invention, a coating dispersion is prepared that comprises microfibrillated cellulose (MFC), a slip aid and at least one hydrocolloid.

A polyfluoroalkyl phosphoric acid ester represented by the general formula [C.sub.nF.sub.2n+1(CH.sub.2CF.sub.2).sub.a(CF.sub.2CF.sub.2).sub.b(CH.sub.2CH.sub.2).sub.cO].sub.mP(O)(OH).sub.3m [I] n: 1 to 6, a: 1 to 4, b: 1 to 3, c: 1 to 3, m: 1 to 3) or a salt thereof. The polyfluoroalkyl phosphoric acid ester represented by the general formula [I] is produced by subjecting a polyfluoroalkyl alcohol represented by the general formula C.sub.nF.sub.2n+1(CH.sub.2CF.sub.2).sub.a(CF.sub.2CF.sub.2).sub.b(CH.sub.2CH.sub.2).sub.2OH [II] (n: 1 to 6, a: 1 to 4, b: 1 to 3, c: 1 to 3) to a dehydration condensation reaction with phosphoric acid. The polyfluoroalkyl phosphoric acid ester can be easily synthesized without passing through dialkyl ester as in the case of phosphonic acid, and used for a mold-releasing agent comprising the same or a salt thereof as an active ingredient.

A manufacturing method of a mold includes the steps of: providing an aluminum base in the shape of a hollow cylinder which is made of a AlMgSi based aluminum alloy, the aluminum base being mechanically mirror-finished; performing a frosting treatment on a surface of the aluminum base with an aqueous solution which contains a salt of hydrogen fluoride and ammonium; thereafter, forming an inorganic material layer on the surface of the aluminum base and forming an aluminum film on the inorganic material layer, thereby forming a mold base; and alternately repeating anodization and etching on a surface of the aluminum film of the mold base, thereby forming an inverted moth-eye structure which has a plurality of micro recessed portions.

A film forming formulation is provided that includes reaction products of phosphoric acid with a strained ring alkoxy silane. The phosphoric acid and the strained ring alkoxy silane are present in a molecular ratio of from 0.9-3.3:1. The film formulation also includes an aqueous solvent. A mold release coating composition is also provided that includes the film forming formulation, a reactive release agent, a base, and an aqueous solvent.

Provided are a super water repellent polymer hierarchical structure, a heat exchanger having super water repellency, and a manufacturing method thereof A super water repellent polymer hierarchical structure can be simply and repeatedly manufactured by using only a method for utilizing a super water repellent hierarchical structure and mechanically molding a polymer material thereon. In addition, a heat exchanger having super water repellency can be provided by providing super water repellency on the fin surface of a heat exchanger by using a dip method and vacuum drying.

The present invention provides a multifunctional mouse pad, including: 200-500 parts of purified terephthalic acid, 300-600 parts of ethylene glycol, 250-400 parts of silicon dioxide, 100-150 parts of hydroxy silicone oil, and 100-200 parts of an internal mold releasing agent. The woven material of the front side of the multifunctional mouse pad has a compact molecular arrangement and is compacted, thickened and integrally woven, and thus the woven material has anti-cut, anti-chop, anti-stab, and bullet-proof functions. The back side of the multifunctional mouse pad is made of the silicone material which is a highly active and strongly-adsorbing material. The main component of the silicone material is silicon dioxide, which is chemically stable and does not burn. The mouse pad body is integrally formed with the front and back sides by thermal compression molding.
