Patent ID: 6989173

Claim:
A method for repairing a damaged area in an insulation material comprising: formulating a patching resin comprising a resinous composition, metal intercalated AlSiO nano structures, and a reactive diluent, wherein the ratio of said metal intercalated AlSiO nano structures to said resinous composition and said reactive diluent is between 3-35% wt; applying said patching resin to said damaged area; and curing said patching resin to produce a patch; wherein said patching resin has a voltage endurance of at least 1000 hours at 188 volts/mil (7.5 kv/mm); wherein the viscosity of said patching resin is between 100-300 cps; and wherein said metal intercalated AlSiO nano structures penetrate said damaged area of said mica insulation material creating a substantially homogenous transition between said damaged area and said patch.
