Abstract:
Equipment for oil and/or gas drilling, completion, storage and transportation, including pressure vessels, tools, pipes, tubes, connections and any other parts is coated with highly structured composite material. Due to its highly structured composition it is a particularly effective barrier to protect metals against attack by corrosive substances such as hydrogen sulfide, carbon dioxide and sea water, if necessary under hydrothermal conditions. At the same time it is also abrasion stable, for example against a grinding effect by sand, as well as resistant to the impact of mechanical load e.g. by tools. This is achieved by a coating comprising a binder comprising at least one cross-linked resin, wherein the resin comprises at least one of polar group; at least one type of hydrophilic flakes with an aspect ratio of more than 10, wherein the surface of the flakes at least partially comprises a metal oxide.
Abstract:
The present invention relates to a cyanate ester resin composition and a prepreg, a laminated material and a metal clad laminated material made therefrom. The cyanate ester resin composition comprises cyanate ester resin, non-halogen epoxy resin, and inorganic filler material, and the structural formula of the cyanate ester resin is as the following: Wherein, n represents an integer between 1 and 50.The cyanate ester resin composition of the present invention has good heat resistance and flame retardance. The laminated material and the metal clad laminated material made from the prepreg that is made from the cyanate ester resin composition, still have good flame retardance and low coefficients of thermal expansion in X, Y directions, without using halogen-containing compounds or phosphorus-containing compounds as the flame retardant, so they are fit for making a substrate material for high density PCB.
Abstract:
The present invention provides a chromium-free surface treatment agent, comprising: a resin compound having a specific bisphenol skeleton; cationic urethane resin emulsion; silane coupling agent; an organic titanium chelate compound; a quadrivalent vanadyl compound; a molybdic acid compound; and water, wherein these components are blended at predetermined ratios such that pH value of the surface treatment agent is in the range of 4 to 5. The one-pack type chromium-free surface treatment agent of the present invention exhibits good stability during storage and is capable of forming on a metal material surface a coating film excellent in corrosion resistance at a bending-processed portion of a steel sheet, solvent resistance and paintability after alkali degreasing.
