The process is particularly suitable for the manufacture of surface coatings. Manufacture of polymeric products. Mixtures of (I) at least one compound containing at least two aziridine groupings per molecule and (II) at least one compound containing at least one ester grouping of the general formula:
Abstract:
A light-curable composition consisting of: (A) a substance containing at least two aromatic or heteroaromatic onitrocarbinol ester groups of the general formula:
IN WHICH Y is an aromatic or heteroaromatic ring system and X is hydrogen or alkyl, aryl alkaryl or aralkyl; and (B) a compound having et laest two aziridine groups or isocyanate groups in the molecule. The photocurable composition of the invention is particularly suitable for the production of coatings and printing plates.
Abstract:
SURFACE COATINGS BASED ON A DISPERSION OF A COPOLYMER (I) WHICH CONTAINS UNITS OF (A) 50 TO 95% BY WEIGHT OF A COPOLYMERIZABLE ESTER OF A MONOOLEFINICALLY UNSATURATED CARBOXYLIC ACID HAVING THREE TO FIVE CARBON ATOMS AND AN ALCOHOL HAVING ONE TO EIGHT CARBON ATOMS; (B) 0.75 TO 25% BY WEIGHT OF AN N-METHYLOLAMIDE OF A COPOLYMERIZABLE OLEFINICALLY UNSATURATED CARBOXYLIC ACID HAVING THREE TO FIVE CARBON ATOMS WHICH HAS BEEN ETHERIFIED WITH AN ALCOHOL HAVING ONE TO EIGHT CARBON ATOMS; AND (D) 0 TO 40% BY WEIGHT OF AT LEAST ONE OTHER COPOLYMERIZABLE MONOOLEFINICALLY UNSATURATED MONOMER. COPOLYMER I IS PREPARED BY POLYMERIZING THE SAID MONOMERS IN AN ORGANIC LIQUID IN WHICH THE COPOLYMER (I) IS INSOLUBLE, IN THE PRESENCE OF A POLYMER (II) OR POLYCONDENSATES (II) OR A MIXTURE OF BOTH WHICH IS DISSOLVED IN THE ORGANIC LIQUID USING A CONVENTIONAL POLYMERIZATION INITIATOR.
Abstract:
A process for the production of coatings, impregnations or bonds by polymerization and cross-linking of mixtures containing olefinically unsaturated esters containing halogen by means of ionizing radiation.
Abstract:
Production of pigmented resin powders by finely dispersing dispersions of pigments in solutions of polymeric materials in at least one organic solvent in water containing a protective colloid while supplying mixing energy, and removing the solvent. A preferred method is to introduce one or more jets of water containing protective colloid at the rate of 5 to 100 m/sec into animpulse exchange chamber together with the dispersion issuing in the immediate vicinity of the orifice(s), and to remove the solvent. The method avoids crosslinking and provides pigmented resin powders of consistently reproducible color which are suitable for conventional powdered-resin coating methods.
Abstract:
A METHOD OF METALLIZING THE SURFACE OF EXPANDED PLASTICS ARTICLES BY APPLYING A LAYER OF A COATING COMPOSITION CONTAINING FINELY DISPERSED IRON PARTICLES AND ELECTROLESS DEPOSITION OF COPPER BY TREATING THE SAID LAYER WITH AN ACID AQUEOUS COPPER SALT SOLUTION, A LAYER OF AN AQUEOUS SOLUTION OR DISPERSION OF AN ORGANIC POLYMER CONTAINING HETEROATOMS BEING APPLIED AND DRIED PRIOR TO APPLICATION OF THE IRON-CONTAINING COATING.
Abstract:
PROCESS FOR DRESSING LEATHER AND SYNTHETIC LEATHER SUBSTITUTES BY APPLYING TO THE LEATHER A COMPOSITION COMPRISING (A) A COPOLYMER CARRYING ACETYL ACETATE GROUPS OR CYANO ACETATE GROUPS, IN THE FORM OF A SOLUTION OR DISPERSION IN AN ORGANIC LIQUID, AND (B) ONE OR MORE ALDEHYDES OR A COMPOUND CAPABLE OF DISSOCIATING TO GIVE AN ALKEHYDE, AND DRYING THE COATING. THE RESULTING DRESSING IS WATERPROOF AND RESISTANT TO SOLVENTS.
Abstract:
COATINGS PREPARED BY REACTION OF POLYISOCYANATES WITH COPOLYMERS CONTAINING HYDROXYL GROUPS AND POLYMERIZED UNITS OF UNSATURATED THIOGLYCOL ETHERS.
Abstract:
Coating, impregnating and bonding agents consisting of suspensions in aqueous solutions of organic polymeric materials of finely divided binders which are insoluble or at the most only slightly swellable in water, which are curable by heat, which are based on polymerizates, polycondensates or polyadducts and which may contain further substances. The suspensions are particularly suitable for coating and impregnation.
Abstract:
THE PRESENT INVENTION RELATES TO COATING COMPOSITONS WHICH MAY BE DEPOSITED ONTO CATHODES AND ARE THUS SUITABLE FOR ELECTROCOATING PROCESSES. THE COMPOSITIONS COMPRISE COPOLYMERS CONTAINING POLYMERIZED UNITS OF (1) AT LEAST ONE NITROGEN-BASIC OLEFINICALLY UNSATURATED COMPOUND, (2) 3A,4,5,6,7A-HEXAHYDRO-4,7-METHANOINDENYL ACRYLATE-5 OR METHACRYLATE-5, (3) AT LEAST ONE COPOLYMERIZABLE OLEFINICALLY UNSATURATED DERIVATIVE OF AT LEAST ONE OXA-ALCOHOL AND, IF DESIRED, (4) FURTHER COPOLYMERIZABLE OLEFINICALLY UNSATURATED MONOMERS, WHICH COPOLYMERS ARE USED FOR ELECTROCOATING IN AQUEOUS SOLUTION OR DISPERSION AT LEAST PARTLY IN THE FORM OF SALTS OF WATER-SOLUBLE ACIDS. THE COMPOSITIONS OF THE INVENTION ARE SUITABLE FOR THE PRODUCTION OF DURABLE COATINGS ON METAL PARTS.
