Description
Nashua 386 Stretch & Seal Silicone Tape
The Nashua 386 Stretch & Seal Tape is a high-performance self-amalgamating silicone tape designed for emergency repairs, sealing, insulating and moisture protection.
Unlike traditional adhesive tapes, Nashua 386 contains no adhesive — it bonds to itself when stretched and wrapped, forming a permanent waterproof and airtight seal. Once applied, it creates a strong rubber-like barrier that resists moisture, UV exposure, chemicals and extreme temperatures.
Ideal for electrical insulation, automotive repairs, plumbing fixes and marine applications.
