Solid insulation material

A combination for producing insulation using a vacuum impregnation process, the combination comprising:

• an impregnating agent;
• a carrier;
• a barrier material;
• a tape adhesive bonding the barrier material to the carrier;
• and
• a first curing catalyst deposited in the tape adhesive;
• wherein the first curing catalyst is (a) inert toward the tape adhesive but (b) reactive with the impregnating agent;
• wherein the impregnating agent includes an impregnating resin comprising a cycloaliphatic epoxy resin at an impregnation temperature in a range from 25 to 100 degrees Celsius, with gelation times of 1 to 15 h at the impregnation temperature, and a second curing catalyst dissolved in the cycloaliphatic epoxy resin making up less than 10% by weight of the impregnating agent;
• wherein the impregnating resin has a viscosity of less than 1500 mPas at the impregnation temperature;
• and
• wherein the second curing catalyst has a lightoff temperature above 100 degrees Celsius.
