tesa® ACXplus 73308 – Black Acrylic Foam Tape (800 μm)

High-Strength Bonding for Powder-Coated and Mixed-Material Assemblies

Product Overview

tesa® ACXplus 73308 is a high-performance, double-sided acrylic foam tape developed for demanding structural bonding applications. With its 800 μm black conformable acrylic core and modified acrylic adhesive, it delivers strong, durable bonds on a wide range of substrates—especially powder-coated surfaces, glass, metals and many plastics. Its viscoelastic properties enable excellent stress dissipation and gap filling, even on irregular surfaces, providing a reliable alternative to screws, rivets, welds, and liquid adhesives. tesa® 73308 is ideal wherever permanent bonding, durability, and aesthetics are critical.

Key Features & Benefits
