Abstract: A method for curing and surface functionalization of molded parts, including processing materials that contain at least one unsaturated radically or cationically curable reactive resin system and further substances to form a molded part and cross-linking the materials up to dimensional stability during or after the processing. The method additionally includes subjecting the molded part to energetic radiation or energetic particles at least one of during the cross-linking and subsequent to the cross-linking to essentially complete curing at least of a surface region of the molded part to produce an essentially completely coatable molded part surface.

Abstract: The invention relates to the fields of chemistry and relates to a method for curing and surface modification of molded parts, which can be used, for example, in the automobile industry, in vehicle construction, in the electrical industry. The object of the present invention is to disclose a method which can be carried out in particular in a short time and with a high degree of reproducibility and leads to an improvement in the surface quality of the molded parts to be painted.

Abstract: The invention relates to the field of chemistry and relates to a coating for wood materials, which serves as a basis for subsequent coatings. The object of the present invention is to disclose a coating, with the aid of which the conductivity of the wood materials is improved. The object is attained by a coating, in which the outer and/or inner surface of a wood material is provided with polyelectrolytes which were dissolved or are or were dispersed in water and/or an organic solvent at least up to processing, with a largely uniform distribution and wherein at least 10 g polyelectrolyte is present per square meter. The object is further attained through a method in which an aqueous solution and/or dispersion of polyelectrolytes is applied on the outer and/or inner surface of wood materials, wherein at least 10 g cationized polyelectrolyte solid is applied per square meter coated outer and/or inner surface of the wood material.

Abstract: The invention is used in the field of chemistry and relates to coatings which can be used, for example, for the production of paint films, and a method for production thereof. The object of the invention is to describe permanent coatings with hydrophobic to ultrahydrophobic properties. The object is attained by hydrophobic permanent coatings of a crosslinked layer of a hardener component (A) and resin component (B), whereby (A) and/or (B) comprise chemically coupled lateral and/or terminal perfluoroalkyl groups with at least one trifluoromethyl end group, with a coupling between the layer and the surface region of the substrate.

Abstract: The invention is used in the fields of chemistry and relates to hardenable materials which can be used for producing lacquers. The aim of the invention is to provide materials which harden at low temperatures in the same amount of time as the others. This is achieved by using hardenable materials containing uretdione groups and containing (A) a binding agent constituent, whereby this component either (A1) does not contain carboxyl groups, or (A2) the concentration of carboxyl groups is less than that of the catalyst (C) or (A3) in the case of a high level of concentration, a quantity of a reactive agent is added. The hardenable materials also contain (B) a polyaddition compound which comprises uretdione groups, and (C) at least one Lewis acid catalyst.

Abstract: The invention relates to the field of chemistry and concerns coated reshaped aluminum semi-finished products and/or components which are coated with a two-step hardening/cross-linking coating agent and a method for the production thereof. The aim of the invention is to disclose and to produce coated reshaped aluminum semi-finished products and/or components which as semi-finished products can still be re-shaped and hardened at high temperatures. The object is attained through coated reshaped aluminum semi-finished products and/or components which are coated with an at least two-step hardening/cross-linking coating agent and at most partially hardened/cross linked, and the formed coating film is elastic.

Abstract: The invention relates to amorphous polyesterimides which comprises 50 to 100 mole-% of units of formula II ##STR1## and from 0 to 50 mole-% of units of formula ##STR2## in which units R.sub.1 and R.sub.2, independentlyof one another, are H, branched or unbranched alkyl radicals having 1 to 6 carbon atoms, branched or unbranched alkoxy radicals having 1 to 6 carbon atoms, or F, Cl or Br.The polyesterimides according to the invention are suitable for the production of molding compositions, moldings, fibers and films.
