ISOSEAL ® MF 0611 consists of a impregnated mixed polyester-glass-fabric combined with a thermo-shrinkable PET-film. ISOSEAL ® MF ME 2411 additionally contains a metallic salt (zincnaphtenate) suitable for epoxy-anhydride systems. During impregnation the resin can penetrate through the layers of the ISOSEAL ® MF tape into the mainwall insulation. During curing process ISOSEAL ® MF will shrink under temperature and prevent resin from draining out and give some pressure to the mainwall of the overhang.
ISOSEAL ® MF is used as final above the porous tapes in the production of VPI-insulation windings to protect the overhang part of low and high voltage coils and bars against ambient stress.
