3M 69 Electrical Grade Glass Cloth Tape is a white glass cloth tape with a high-temperature thermosetting silicone pressure-sensitive adhesive. It is designed for use in 600-volt dry location applications motors, and transformers with and without varnish coating. Key attributes like high mechanical strength and resistance to high temperatures provide excellent performance. The thermosetting adhesive provides an increased bond once applied in areas of high ambient temperatures. The
thermosetting adhesive provides elevated temperature performance up to Class N 392F (200C) temperature rating.
3M 69 provides insulation and solvent-resistant protection for use as coil cover, anchor, banding and core, layer and crossover insulation. This tape features a noncorrosive adhesive. It is conformable, printable and flame retardant.
Features & Benefits
- High-temperature thermosetting adhesive has excellent solvent resistance.
- Class B rating to Class H provides for high temperature resistance.
- Glass cloth backing gives mechanical protection which lasts longer and improves safety.
Uses & Applications
- Insulating electric and induction-type furnace power supply leads.
- Securing high-temperature, non-PSA insulation (such as asbestos and glass) in high-temperature areas.
- Securing Scotch® Fire Retardant Electric Arc Proofing Tape 77.
- Splicing wire SF and SFF rated 302° F (150° C), 356° F (180° C) .
- Reinsulating and repairing coils on mining machines.
- Splicing silicone-covered glass wire where splices require more abrasion resistance and mechanical strength than can be provided by silicone tapes Insulating Class "H" dry-type transformer leads.
- Insulating splices made on SA type wire in heat treat areas.
- Especially suited to high-temperature applications.
- Used in a variety of coil/transformer and motor applications, including an outer wrap for bobbin wound coils, banding arbor wound coils, lead pad hold down, end turn and lead anchor and connection.
Made in the U.S.
* Multiple cases may be shipped per package in order to minimize the charge for shipping.

QUESTION: Could you use this to wrap a cold water copper pipe to avoid condensation/sweating? Thank you
: No, this tape is typically used for electrical applications. For wrapping pipes to prevent condensation we most often sell Shurtape IT-100 at https://www.findtape.com/p556
. Thank you.
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
