2. A pplications
• Insulating electric and induction type furnace power
supply leads
• Securing high temperature, non-PSA insulations (such as
asbestos and glass) in high temperature areas
• Securing Scotch 77 Fire Retardant Electric Arc Proofing
Tape
• Replacing 3M 27 Glass Cloth Electrical Tape in locations
where a higher-temperature tape is needed
• Reinsulating and repairing coils on mining machines
• Reinforcing insulation in electrical installations where
heavy loads cause high heat and breakdown of original
