  • Patent number: 8915998
    Abstract: The invention relates to a pigment granulate which contains 40 to 65% by weight of pigment and at least 10% by weight of a compound of general formula (I) CH3—(CH2)n—CH2—O—[(CH2)p—O]m—H, wherein n=8-18, p=1-4 and m=35-100, the weight ratio of the compound of general formula I to the pigment being ? the STSA surface area of the pigment in m2/g multiplied by 0.0021 g/m2 and the mass-weighted particle size of the pigment granulate being <20 ?m. The pigment granulate can be produced by dispersing the pigment and the compound of formula I in a solvent and then drying the dispersion obtained. The pigments according to the invention can be used for dying and/or the antistatic finishing in water-based paints and lacquer systems, dispersion on paints, printing inks, ink systems and coating systems.

  • Publication number: 20120190755
    Abstract: The invention relates to a one-component, storage-stable formulation for marking road surfaces. The invention in particular relates to a formulation for roadway marking comprising encapsulated radical initiators which do not influence the storage stability of the roadway marking and are simple to break open upon application in order to release the initiator.

  • Publication number: 20120171492
    Abstract: The invention relates to the production of core-shell particles for encapsulating reactive components for single-component resin systems. In particular, the invention relates to the encapsulation of radical initiators such as peroxides. The invention further relates to a method for the 100% encapsulation of reactive components, whereby novel, storage-stable resin systems can be provided. At the same time, the core-shell particles are designed such that they can be opened nearly completely, easily and quickly during application, but have sufficient storage and shear stability before application.
