Abstract

Official abstract text for this publication.

Tape adhesives suitable for impregnating processes for insulation systems are described. Embodiments of the tape adhesives include solid insulation material such as mica, anhydride-free impregnating resins and accelerators for the anhydride-free impregnating resins. The tape adhesives may be adjusted with respect to the reactivity of the accelerators for the anhydride-free impregnating resins in relation for the storage stability of the overall insulation systems.

First claim

Opening claim text (preview).

What is claimed is: 1. An insulation system comprising a solid insulation material, an anhydride-free impregnating resin, an accelerator, and an oxirane group free tape adhesive having a viscosity of about 5 to about 20 Pa*s at about 70° C., wherein the tape adhesive comprises an addition product formed from an A(OH) n segment comprising bisphenols, diols, triols, and/or higher alcohols, with a Cy segment comprising at least one compound selected from the group consisting of a cyclohexene oxide and a cyclohexene oxide derivative. 2. The system of claim 1 , wherein the accelerator comprises a tri-N-methylpiperazine derivative of trimethylolpropane trimethacrylate. 3. The system of claim 1 , wherein the tape adhesive is present together with the accelerator in a blend, wherein the blend comprises from about 50% to about 99.5% tape adhesive by weight. 4. The system of claim 1 , wherein the tape adhesive is present together with the accelerator in a blend, wherein the blend comprises from about 60% to about 95% tape adhesive by weight. 5. The system of claim 1 , wherein the tape adhesive is present together with the accelerator in a blend, wherein the blend comprises from about 70% to about 90% tape adhesive by weight. 6. The system of claim 1 , wherein the solid insulation material comprises mica. 7. An insulation system comprising a solid insulation material comprising mica, an anhydride-free impregnating resin, an accelerator comprising a tri-N-methylpiperazine derivative of trimethylolpropane trimethacrylate, and an oxirane group free tape adhesive having a viscosity of about 5 to about 20 Pa*s at about 70° C., wherein the tape adhesive comprises an addition product formed from an A(OH) n segment comprising bisphenols, diols, triols, and/or higher alcohols, with a Cy segment comprising at least one compound selected from the group consisting of a cyclohexene oxide and a cyclohexene oxide derivative. 8. The system of claim 7 , wherein the tape adhesive is present together with the accelerator in a blend, wherein the blend comprises from about 50% to about 99.5% tape adhesive by weight. 9. The system of claim 7 , wherein the tape adhesive is present together with the accelerator in a blend, wherein the blend comprises from about 60% to about 95% tape adhesive by weight. 10. The system of claim 7 , wherein the tape adhesive is present together with the accelerator in a blend, wherein the blend comprises from about 70% to about 90% tape adhesive by weight.
