Electrical Insulation System

Impregnating resin

Single component, epoxy VPI resin, high thermal stability

Epoxylite ® TSA 220 FM is a single component, 100 % solids epoxy VPI resin specifically designed for VPI impregnation of traction armatures and coils which can operate at temperatures up to 220 ° C.

Epoxylite ® TSA 220 FM is a specifically formulated version of Epoxylite TSA 220 S to provide improved film coating and film build. This product can be processed without pre-heating.

Epoxy resins of this type are 100% solids systems resulting in low emissions on cure. Polymerization of the pre-catalysed product is initiated by heat and occurs as a rapid chain reaction until a three dimensionally, cross-linked, duroplastic cured material has been produced.

The resin system is compatible with most commonly used insulation materials /systems and in conjunction with suitable insulation components will operate at temperatures up to 220ºC.
