    摘要： The invention relates to a method for drying water-based coating compounds. The inventive method comprises the following steps: a) providing a water-based coating compound; b) applying the water-based coating compound to at least part of the surface of a casting mold; c) optionally partially or completely rendering the applied water-based coating compound mat, a part of the support liquid of the coating compound passing into the substrate depending on the time elapsed; d) applying a flammable liquid to the likewise matted layer of the water-based coating compound; and e) completely burning off the flammable liquid.

    摘要： The invention relates to a synthetic resin, based on partly cross-linked poly(meth)acrylate-urethane-(meth)acrylates in urethane(meth)acrylates, obtained by: (a) preparation of (meth)acrylate monomers (I), which have no groups reactive to isocyanate groups and (meth)acrylate monomers (II), with (a) group(s) reactive to isocyanate groups, (b) polymerisation of the (meth)acrylate monomers (I) and (II) to give a poly(meth)acrylate (III), with groups reactive to isocyanate groups, (c) reaction of the poly(meth)acrylate (III) with an isocyanate compound (IV), with more than one isocyanate group, in such a manner that 5 to 40 % of the isocyanate groups of the isocyanate compound (IV) react with the above groups reactive to isocyanate groups, whereby partial cross-linking of (III) with an increase in weight average molecular weight by a factor of 2 to 20 occurs, in which one given (IV) reacts with more than one of the isocyanate groups thereof with more than one given (III) and (d) reaction of the compound obtained in (c) with (meth)acrylate monomers (II). The synthetic resin can be used as a binder, for example, in a radical-hardening composition, suitable for application in production of composite materials, composite workpieces, and paints with advantageous physical and chemical properties.

    摘要： Die Erfindung betrifft Zusammensetzungen, enthaltend Gießereisand und Additiv, wobei das Additiv Kryolith umfaßt. Durch die Verwendung eines solchen Additivs bei der Herstellung von Gießereikernen und -formen werden sogenannte Blattrippen beim Abgießen deutlich vermindert bzw. ganz verhindert.
