Liquid Electrical Tape is a professional-grade, brushable insulating sealant that forms a durable, flexible rubber-like dielectric coating when cured. Designed to replace traditional electrical tape in hard-to-reach, irregular or exposed applications, it delivers a seamless, airtight, waterproof barrier that prevents moisture intrusion, corrosion, short circuits and electrical leaks.
This fast-drying liquid insulation adhesive adheres strongly to metal, copper, aluminum, plastic, rubber, vinyl and composite surfaces. It cures to a tough yet flexible finish that remains stable across extreme temperatures (-50°F to 275°F / -45°C to 135°C), resists UV rays, oils, acids, alkalines, solvents and abrasion. Unlike tape, it will not peel, crack, unravel or deteriorate over time.
Easy to apply with an integrated brush, it builds into thick insulating layers (typically 2–3 coats) and fully cures in 24 hours for long-lasting protection. Widely used in automotive, marine, RV, industrial, outdoor lighting, underground wiring and household electrical repairs where reliable insulation and weatherproofing are critical.

Features:

  • Brush-on liquid formula for precise, easy application to irregular shapes & tight spaces
  • 100% waterproof & weatherproof seal blocks moisture, rain & humidity
  • Superior dielectric insulation (up to 1,276V/mil) prevents shorts & shocks
  • UV & chemical resistant (oils, acids, alkalis, solvents)

Applications:

Liquid electrical tape is widely used for waterproofing, insulating, and sealing electrical connections in automotive wiring harnesses, marine and boat electrical systems, RV and trailer lighting, outdoor landscape lighting, underground low-voltage cables, and household electrical repairs.

It provides reliable protection for wire splices, terminals, frayed cords, circuit boards, sensors, and junction boxes, while also resisting corrosion, vibration, UV exposure, and harsh weather conditions, making it ideal for industrial, outdoor, marine, automotive, and DIY electrical applications that require durable, long-lasting insulation and sealing.
