A process for the production of flexible impregnated protective, auxiliary and insulating materials on a fibre basis for electrical purposes by the application of an impregnating agent to the material to be impregnated, followed by curing, characterised in that a solvent-free impregnating mass containing one or more olefinically unsaturated, radically polymerisable polyesters, which contain one or more radically polymerisable monomers as reactive diluents, one or more plasticizing agents and optionally one or more peroxide-free radical initiators is applied to the material to be impregnated and curing is then carried out with high energy radiation and optionally by further heating.
A process for the production of flexible impregnated protective, auxiliary and insulating materials on a fiber basis for electrical purposes by the application of an impregnating agent to the material to be impregnated, followed by curing, characterized in that a solvent-free impregnating mass containing one or more olefinically unsaturated radically polymerized polyesters containing one or more polymerized monomers as reactive diluents, one or more plasticizing agents and optionally one or more peroxide-free radical initiators is applied to the material to be impregnated and curing is then carried out with UV-radiation and optionally by further heating.
A process for the production of impregnated protective and insulating materials on a fiber basis for electrical purposes by the application of an impregnating agent to the material to be impregnated, followed by curing, characterized in that a solvent-free impregnating mass of one or more olefinically unsaturated, radically polymerized polyesters, one or more plasticizing agents and optionally containing one or more heat activated peroxide-free radical initiators is applied to the material to be impregnated and curing is then carried out with electron radiation optionally followed by heating.
A process for the production of flexible impregnated protective, auxiliary and insulating materials on a fiber basis for electrical purposes using solvent-free masses of one or more olefinically unsaturated, radically polymerized polyesters containing one or more polymerized monomers as reactive diluents, one or more plasticizing agents and optionally one or more peroxide-free radical initiators, as an impregnating material.
