High-strength, permanent bonding solution with long-term durability
Viscoelastic acrylic foam core for excellent conformability and stress dissipation
Bonds well to high, medium, and low surface energy materials including powder coated surfaces, metals, plastics and glass
All product featuresProduct description
tesa® 73311 acrylic core tape is a high-performance, double-sided foam tape engineered for demanding bonding applications. With its black, 1100 µm thick conformable acrylic core and modified acrylic adhesive, it delivers strong, durable bonds. It is especially well-suited for most powder-coated surfaces, as well as glass and many plastic materials, offering versatile bonding capabilities across a wide range of substrates. Designed to replace traditional mechanical fasteners, it enables sleek, clean designs without compromising strength. Its viscoelastic properties ensure excellent stress dissipation and gap filling, even on irregular surfaces. tesa® 73311 is ideal for permanent bonding where reliability and aesthetics are key.
