Abstract

Claims (15)

1 . An impregnation resin for insulation systems using a wrapping tape, the resin comprising:

a base resin including a siloxane-containing compound and a hydrocarbon-based compound; and

a siloxane-based curing agent with cationic and anionic curing catalysts, the curing agent causing the base resin to cure to a thermoset material;

wherein the siloxane-containing compound forms a —SiR 2 —O— backbone in the thermoset material;

the hydrocarbon-based compound forms a —CR 2 — backbone in the thermoset material;

wherein R represents an organic radical selected from the group consisting of: aryls, heterocycles, nitrogen-substituted aryls or alkyls, oxygen-substituted aryls or alkyls, and sulfur-substituted aryls or alkyls; and

the siloxane-containing compound makes up between 20 and 30 mol % of the base resin and the hydrocarbon-based compound makes up between 70 and 80 mol % of the base resin.

2 . The impregnation resin as claimed in claim 1 , wherein the siloxane-containing compound comprises a monomeric form.

3 . The impregnation resin as claimed in claim 1 , wherein the siloxane-containing compound comprises an oligomeric form.

4 . The impregnation resin as claimed in claim 1 , wherein the siloxane-containing compound comprises a glycidyl- and/or glycidoxy-functionalized compound.

5 . The impregnation resin as claimed in claim 1 , wherein the base resin comprises a glycidyl ether compound.

6 . The impregnation resin as claimed in claim 1 , wherein the base resin comprises a cycloaliphatic epoxy resin.

7 . The impregnation resin as claimed in claim 1 , wherein the siloxane-containing compound comprises an epoxy-terminated aryl- and/or alkylsiloxane.

8 . The impregnation resin as claimed in claim 1 , further comprising 1,3-bis(3-glycidyloxyalkyltetramethyldisiloxane).

9 . The impregnation resin as claimed in claim 1 , further comprising 1,3-bis(3-glycidyloxypropyl)tetramethyldisiloxane.
