Non-ionic emulsifiers

Process for preparing coating powder compositions and their use for

A process for producing a repair coating This invention relates to a process for producing a multi-layer repair coating by the application of a transparent clear lacquer coat, which is unpigmented or which contains colourless pigment, to a predried or hardened colour- and/or effect-imparting base pigment coat, or by the application of a pigmented covering lacquer coat to an optionally precoated substrate. Binder vehicles which are hardenable exclusively by radical polymerisation are used for the production of the transparent clear lacquer coat or of the pigmented covering lacquer coat, and hardening is effected by means of pulsed, high-energy UV radiation.

Process for producing a repair coating

Aqueous emulsion of one or more water dilutable epoxide resins, containing

Aqueous emulsion of chlorinated polyolefines, the preparation thereof,

Two component-coating agents and emulsions which can be used for their preparation. The coating agents contain:

Aqueous coating agent and aqueous emulsion, process for the preparation

A catalyst-free single-component coating agent containing (A) one or more compounds acting as cross-linking agents and with on average at least two CH-azide hydrogen atoms, (B) one or more (meth)acrylate copolymers, polyester resins and/or polyurethane resins capable of Michael addition, with .alpha., .beta.-unsaturated groups bonded via carbonyl, carboxyl and/or carboxylic amide groups, a C.dbd.C equivalent weight of 85-1800 and a weight average molecular weight of 170-50000. The equivalent ratio of A to B is 2:1 to 1:2. The coating agent contains solvents and conventional lacquer additives, and optionally contains water, pigments and/or fillers. It results in particularly acid-resistant coatings and is particularly suitable for producing covering lacquer and clear lacquer coatings in the motor-vehicle sector.

Catalyst-free single-component coating agent and use thereof for

An aqueous coating agent on the basis of one or more polyols having ionic groups or groups convertible into ionic groups, which can contain pigments, fillers and/or optional conventional lacquer adjuvants and/or solvents, comprising
