Premium double-coated bonding tape with polyester carrier, 3/8 inch x 360 yards, 18 rolls per case. Delivers excellent adhesion to metals, plastics, and dissimilar substrates with superior holding power across -40°F to 300°F temperature range.
3M™ Double Coated Tape 93020LE is a market-proven, high-performance bonding solution featuring a polyester film carrier with adhesive on both sides. This versatile tape delivers excellent bond strength to a wide variety of substrates including metals, plastics, glass, papers, and painted surfaces. The tape is specifically engineered for applications requiring premium performance with a thicker profile, offering superior holding power and anti-lifting properties. With dimensions of 3/8 inch width and 360 yards length, this tape comes in a case of 18 rolls, making it ideal for high-volume industrial applications.
Manufactured using a solventless process, 3M™ Double Coated Tape 93020LE features the High Strength Acrylic Adhesive 300LSE family formulation, which provides very high initial adhesion and bond strength that increases with time and temperature. The tape performs exceptionally well across a broad temperature range from -40°F to 300°F, with excellent resistance to industrial chemicals, consumer chemicals, moisture, and humidity. The polyester carrier provides dimensional stability to foams and other substrates, making it significantly easier to handle during slitting and die-cutting operations.
This industrial-grade tape is ideal for consumer and industrial electronic device assemblies, plastic assembly bonding, automotive applications, appliance component assembly, medical equipment fabrication, and general industrial attachment. The tape meets UL746C standards and is particularly effective for bonding dissimilar substrates, including low surface energy materials like powder coatings and polypropylene plastics. With its splice-free design and tan 58 lb. polycoated kraft paper liner, this tape is perfect for converting and die-cutting applications in manufacturing environments.
