^{3M Tape 1276 Paper-Backed Filament Tape with Oil-Saturable Backing Acrylic Adhesive  停產 No longer Avaialbe}

3M Filament Reinforced Electrical Tape 1276 is a 9 mil glass filament-reinforced paper backing with high-shear strength acrylic adhesive. Solvent-resistant, it offers good tensile strength for holding in oil-transformer applications.

3M Electrical Tape 1276 is made of an electrical-grade paper backing, reinforced with parallel glass filaments and an oil-compatible acrylic pressure-sensitive adhesive.
Unlike conventional film-backed tapes, this products' paper backing construction provides for complete impregnation and saturation of the tape in adjacent layers of insulation. This feature minimizes the possibility of voids leading to corona discharges, with subsequent deterioration of insulation materials. Polyester film used in making traditionally designed filament tapes does not absorb transformer oil. The unique coating on the back side of 1276 tape promotes exceptional bonding of the diamond paper insulation epoxy during the transformer baking process.

· Stable adhesive even after long exposure to transformer fluids
· Saturable backing for air entrapment resistance
· Minimal air trapped between adhesive layers in tape
· Minimum contamination of oil power factor and interfacial tension
· Stiffness for superior handling, which promotes operator efficiency
· Diamond paper insulation thermal bonding compatibility with back side of tape
