Adhesive tape 3M 70071091717 — strong bonding, waterproof

3M adhesive tape 70071091717 is a double-sided waterproof bonding tape designed for durable joins and moisture-resistant seals. The tape offers consistent adhesion to a variety of common substrates used in household, workshop and light industrial settings. It is intended for applications where strong bonding and resistance to humidity or occasional water exposure are required, providing a compact and easy-to-apply solution for repairs, mounting and reinforcement tasks.

Advantages

The tape provides reliable, high-strength adhesion on materials such as metals, plastics and painted surfaces while maintaining waterproof performance. Its double-sided construction allows for clean, low-profile joins without mechanical fasteners. The product maintains bond strength over time and reduces the need for solvents or curing steps. The material is thin and conformable so it adapts to slightly uneven surfaces and creates a neat finish.

Suitable for

• Mounting trims, nameplates and lightweight panels
• Sealing joints and edges exposed to moisture
• Temporary or permanent repairs of housings and enclosures
• Bonding dissimilar materials where screws or rivets are undesirable

Key specifications

• Adhesive type: pressure-sensitive, double-sided
• Water resistance: suitable for moisture exposure and splash protection
• Substrate compatibility: metals, rigid plastics, painted and coated surfaces
• Thickness: thin and conformable for low-profile joins
• Application temperature range: performs across typical indoor and workshop temperatures

How to use

Ensure both bonding surfaces are clean, dry and free from dust, oil or loose particles. Cut the required length of tape and apply firm, even pressure across the bonded area to activate the adhesive. For best results, apply pressure for several seconds and allow the bond to set; no additional curing step is necessary. When bonding to flexible or irregular surfaces, press the tape into contours to maximise contact area.

Usage recommendations

For optimal adhesion, prepare surfaces with a suitable cleaner and avoid bonding in the presence of heavy contaminants or extreme temperatures. While the tape is waterproof and resists moisture, it is not intended for continuous immersion; select a specialized structural sealant for permanent underwater use. Store in a cool, dry place away from direct sunlight to preserve adhesive performance.
