Method for the production of electrical pressure sensitive insulating tapes
Abstract
Abstract A SOLUTION OF A COPOLYMER IS APPLIED TO A BASE MATERIAL. THE COPOLYMER COMPRISES 65 TO 90% BY WEIGHT, BASED ON TOTAL MONOMER WEIGHT, OF AT LEAST ONE ESTER OF ACRYLIC ACID WITH A STRAIGHT OR BRANCHED CHAIN PRIMARY OR SECONDARY ALCOHOL HAVING 4-12 CARBON ATOMS, 10 TO 30% BY WEIGHT, BASED OON TOTAL MONOMER WEIGHT, OF AT LEAST ONE N-VINYL LACTAM HAVING THE GENERAL FORMULA CH2=CH-N<(-CO-(CH2)N-) WHEREIN N IS 3, 4 OR 5 AND 0-20% BY EIGHT, BASED ON TOTAL MONOMER WEIGHT, OF AT LEAST ONE MODIFYING MONOMER COPOLYMERIZABLE WITH THE ABOVE RECITED MONOMERS. THE RESULTANT COATING IS DRIED. AN ELECTRICAL INSULTATING TAPE COMPRISING A PRESSURE SENSITIVE SELF-ADHESIVE COATING ON A CARRIER MATERIAL IS THEREBY OBTAINED. THE TAPE HAS IMPROVED ADHESION, COHESION ND GRIPPING CAPACITY.
