Premium double coated transfer tape with polyester carrier, excellent adhesion to metals and plastics, temperature range -40°F to 300°F, ideal for industrial bonding and assemblies.
3M™ Double Coated Tape 93020LE is a market-proven, premium performance double coated transfer tape engineered for superior bonding across diverse materials and applications. Featuring a polyester film carrier with low surface energy acrylic adhesive on both sides, this tape delivers excellent bond strength to similar and dissimilar materials including metals, most plastics, glass, papers, and painted surfaces. The tape is ideal for applications requiring dimensional stability and ease of handling during slitting and die-cutting operations.
This versatile bonding solution offers exceptional performance across a wide temperature range from -40°F/-40°C to 300°F/148°C, with bond strength that increases as a function of time and temperature. The tape demonstrates very high initial adhesion and excellent holding power with anti-lifting properties, making it suitable for both consumer and industrial electronic device assemblies, plastic bonding in automotive applications, appliance component attachment, and medical equipment fabrication. Manufactured using a solventless manufacturing process, this tape meets UL746C specifications and is part of the 3M™ High Strength Acrylic Adhesive 300LSE family.
The 93020LE comes supplied on a tan 58 lb. polycoated kraft paper liner, optimized for die-cutting and converting applications. With good resistance to industrial chemicals, consumer chemicals, moisture, and humidity, this tape provides reliable performance in demanding industrial environments. Its 54-inch overall width and 7.9 mil total thickness make it ideal for large-scale manufacturing operations requiring consistent, high-quality bonding performance.
