摘要:
A particle filled resin system is produced by cavitation. A method of producing a filled resin system comprises providing a resin and a filler, and subjecting the resin and filler to cavitation. A method of changing the rheology of a filled resin system comprises subjecting the filled resin system to cavitation.

A multilayer laminated structure suitable for use in flexible laminate packaging such as retort pouches contains a sealable layer and an imaging layer. The imaging layer is capable of recording a latent image (by image-wise exposure to actinic radiation, for example) that can be activated to form an image (for example, by operation of an externally applied agent such as pressure and/or heat upon the imaging layer). The sealable layer is utilized to form pouches and other containers from the multilayer laminated structure.

The present invention is directed to systems and methods for automatically applying a tape, such as an adhesive, to a work-piece. According to one embodiment of the present invention, there is provided a system and method for a robotic tape applicator that includes a computer apparatus, a tape applicator apparatus, and an apparatus for holding a work-piece in registration with the tape applicator apparatus for tape application in response to programming data from the computer apparatus. Other components, such as a tape cutting apparatus, a splicing apparatus, adhesion promoter apparatus, and/or optical system can be added to assist and enhance the tape application process.
摘要:
The present invention provides a surface treatment method for magnesium alloys that can form a uniform, fine, and dense conversion coating on a magnesium alloy surface on which mold release agent, an oxide layer, and an alloying component (e.g., aluminum and zinc) segregation layer are potentially present, and also provides magnesium alloy members whose surface has been treated by the aforesaid surface treatment method. The surface treatment method of the present invention comprises a degreasing process to degrease the surface of the magnesium alloy, a chemically etching process to chemically etch the alloy, and a conversion treatment process to form a conversion coating. The chemical etching forms a magnesium phosphate coating having a coating weight of 10 to 2,000 mg/m2, measured as phosphorus, by bringing the surface of the magnesium alloy into contact with an aqueous solution containing a phosphoric acid-type compound.

A metal article whose surface is coated with a coating composition composed of (A) a silane coupling agent component, (B) a polymer component having a specific chemical structure, and (C) a wax component provides a chromium-free surface treated metal material with superior corrosion resistance, paintability, fingerprint resistance, and workability.
摘要:
The invention relates to a method for providing a metal surface with an anti-corrosion treatment. Said method is characterized in that the metal surface is brought into contact with a homo- or copolymer of vinylpyrrolidone. The invention also relates to a solution for application, containing a) 0.02 to 20 g/l phosphoric acid and/or at least one fluoro acid of one or more elements of the following group: Zr, Ti, Hf and Si; or their respective anions and b) 0.05 to 20 g/l of a homo or copolymer of vinylpyrrolidone; and to a concentrate for the same.
