The invention relates to an overcoat lacquer containing a) at least one binding agent containing alkyd resins made from tris-(2-hydroxylethyl)-isocyanurate, 2,6-naphthaline dicarboxylic acid, drying fatty acids, and, optionally, other components known from alkyd resin chemistry, b) at least one solvent or at least one technical solvent or mixture thereof based on hydrocarbon and c) at least one siccative or at least one mixture of siccatives or several anti-skin agents.
摘要:
The present invention relates to a polyamideimide resin solution preparable by reacting (a) aromatic polycarboxylic acids and/or their anhydrides with (b) aromatic imide- and amide-forming components in cresol at temperatures above 170° C., to the use of this polyamideimide solution for the preparation of wire enamels, to the wire enamels in question, and to the enamelled wires coated therewith.
摘要:
The present invention relates to coating compositions for flat assemblies, hybrids, SMD assemblies, comprising at least one binder or binder mixtures which are curable at 60° C.-120° C., preferably at 70° C.-110° C., more particularly at 80° C.-90° C., and also to a process for preparing them and to their use for flat assemblies in electronics, hybrids, SMD assemblies and assembled printed circuit boards.
摘要:
The invention relates to mixtures of preferably from 80 to 99.9% by weight, based on the mixture, of a solution S1 comprising one or more polyamidocarboxylic acids and preferably from 0.1 to 20% by weight, based on the mixture, of a solution S2 comprising one or more, preferably primary, diamines and one or more tetracarboxylic acid diesters, processes for producing polyimide coatings using such mixtures, the use of such mixtures for producing polyimide coatings, and also polyamide-coated articles obtainable using such mixtures.

摘要:
The invention relates to novel liquid epoxy resin emulsions which contain the following components, dissolved and/or dispersed in water: (A) at least one binding agent selected from the group made of epoxy resins and modified epoxy resins, (B) at least one non ionic thickener and (C) at least one catalyst for hardening, produced by reacting at least one boron trifluoride complex with at least one compound containing at least one epoxy group. The invention also relates to a method for the production and use thereof as an impregnating varnish for electrotechnical components, particularly for electrical winding items.
摘要:
The invention relates to wire enamels comprising as binders polyesterimide and/or polyamideimide, the binders comprising as monomeric building blocks polyoxyalkylenediamine having terminal amino groups. The polyoxyalkylenediamines are preferably selected from the group polyoxyethylenediamine, polyoxypropylenediamine and polyoxyethylenepropylenediamine. The invention also encompasses the use of the novel wire enamels for coating copper wires, especially thick round wires or profiled wires.
摘要:
Thermoplastic elastomer mixture which comprises at least one thermoplastic elastomer TPE, with the exception of a thermoplastic polyurethane TPU, and at least one filler from the group of precipitated silica, or precipitated silicate or carbon black.The thermoplastic elastomer mixtures are produced by, in a first step, mixing at least one filler selected from the group of precipitated silica, or precipitated silicate or carbon black, and at least one thermoplastic to give a masterbatch and, in a second step, mixing the masterbatch with at least one thermoplastic elastomer, with the exception of a thermoplastic polyurethane TPU.The thermoplastic elastomer mixture can be used in injection-moulded items.
