摘要:
To provide a powder coating material capable of forming, by one coating, a cured film which has a double-layered structure comprising a cured resin layer and a fluororesin layer and which is excellent in weather resistance, wherein the fluororesin layer is less likely to be peeled for a long period of time; a coated article; and processes for their production. The powder coating material comprises a powder (X) composed of a composition (±) comprising a fluororesin (A) and an ultraviolet absorber (B), and a powder (Y) composed of a composition (²) comprising a thermosetting resin (C) other than a fluororesin, a curing agent (D) and a light stabilizer (E).
摘要:
Mit dem Einsatz eines Heißsiegellacks, der auf Styrol-haltige Copolymere, Poly(meth)acrylaten, mindestens einem Polyester und optional einem Tackifier beasiert, sowie dem Verfahren zur Versiegelung einer mit einem solchen Lack beschichteten Folie kann eine transparente, heißsiegelfähige Beschichtung für transparente PET-Verpackungsfolien bereitgestellt werden. Überraschend ist dabei, dass trotz des Einsatzes eines optisch nicht mit Polyestern und Polymethacrylat verträglichen Kautschuks auf Basis styrolhaltiger Polymere, die Transparenz der Heißsiegelbeschichtungen sehr hoch bleibt.

The instant invention provides an aqueous dispersion, a coating composition, coating layers and coated article made therefrom. The coating composition according to the present invention comprises: (1) the inventive aqueous dispersion comprising the melt blending product of: (a) from 50 to 99 percent by weight of one or more first polyesters, based on the total solid content of the dispersion, wherein said one or more first polyesters have an acid number in the range of from less than 15, for example less than 10, or in the alternative less than 5, based on the total solid content of the one or more first polyesters; (b) from 1 to 50 percent by weight of one or more stabilizing agents comprising at least one second polyester, based on the total solid content of the dispersion, wherein said second polyester has a carboxylic acid group and an acid number equal to or greater than 15, for example greater than 20, based on the solid content of the second polyester; (c) one or more neutralizing agents; and (d) from 15 to 90 percent by weight of water, based on the total weight of the dispersion; wherein said dispersion has a solid content of 10 to 85 percent, based on the total weight of the dispersion; and (2) one or more cross-linking agents.
摘要:
The present invention provides a laminated polyester film which can be suitably used in the applications requiring a good visibility and a good adhesion property to a hard coat layer, etc., for example, such as various kinds of optical films as members of liquid crystal displays as well as molding films. The laminated polyester film of the present invention comprises a polyester film and a coating layer formed on at least one surface of the polyester film which is produced by applying a coating solution comprising a polyester resin having a naphthalene skeleton, a metal oxide, and two or more kinds of crosslinking agents, thereonto.
摘要:
It is an object of the present invention to provide a water-based composite resin composition which has an excellent long-term storage stability and which enables formation of a coating film having an excellent water resistance and solvent resistance. The present invention relates to a water-based composite resin composition and a coating agent; the water-based composite resin composition containing composite resin particles (A) and an aqueous medium (B), the composite resin particles (A) containing polyester resin (a1) particles having a sulfonate group and an epoxy resin (a2) of which some or all parts are encapsulated in the polyester resin (a1) particles, wherein a mass ratio [(a1)/(a2)] of the polyester resin (a1) to the epoxy resin (a2) in the composite resin particles (A) is in the range of 95/5 to 30/70.
摘要:
An insulated wire, comprising an electrical conductive core and an insulating layer of a polymer composition surrounding the electrically conductive core, which polymer compositions contains: (A) a metal salt of a phosphinic acid and/or a diphosphinic acid and or a polymer thereof, (B) ammoniumpolyphosphate (C) an oligomer or a polymer of a triazine derivative.
摘要:
A coating composition comprising components A, B and optionally C, wherein component A comprises at least one hydroxy-terminated polyarylate. Component B is an organic species which can react with the hydroxy terminal groups of component A, and component C is a catalyst or mixture of catalysts. The hydroxy-terminated polyarylates are prepared by a solution polymerization method.
