  • Patent number: 8034853
    Abstract: The invention provides a powder coating composition prepared from a combination, the combination comprising: A) at least one binder resin and, optionally at least one curing agent, B) at least one calibrated pigmented liquid, based on at least one pigment, and, C) optionally, at least one pigment and/or extenders and/or additive. The powder coating composition of the invention provides a precise color of the coatings having a desired color with high color stability. Therefore there is no need for additional adjustment tests or re-working procedures, and, therefore, it makes it possible to offer efficient, small-batch manufacture of custom colors, for example, to match a swatch of fabric supplied by a customer.

  • Patent number: 8013038
    Abstract: The object of the invention is a method for the dispersion of reactive monomers, wherein a monomer emulsion (8) is fed at a first pressure through a dispersion jet (7) and a second dispersion (9) is fed laterally behind the dispersion jet at a second pressure that is less than the first pressure, both the emulsion and the dispersion being dispersed with one another in a mixing chamber. Using the method, nanoparticle-laden monomer emulsions may be produced that, after polymerization, produce polymer-coated nanoparticles.

  • Patent number: 7960466
    Abstract: The present invention provides a natural rubber masterbatch effective in achieving a tread rubber composition which is suitable for heavy-duty tires for rough roads and which is effective in greatly enhancing the abrasion resistance of the tires without impairing the low heat build-up of the tires, a method of producing the natural rubber masterbatch, a rubber composition prepared using the natural rubber masterbatch, and a tire. In a mixing step of mixing a natural rubber latex with a slurry containing water and a carbon black dispersed therein, 10 to 100 weight parts of the carbon black is mixed with 100 weight parts of a natural rubber component in the natural rubber latex. The carbon black satisfies the following conditions: (1) N2SA is 120 to 180 m2/g; (2) the relationship between 24M4DBP and N2SA is represented by the inequality 15?24M4DBP?0.
