tesa® ACXplus 73305 – Black Acrylic Foam Tape (500 μm)

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

Product Overview

tesa® ACXplus 73305 is a high-performance, double-sided acrylic foam tape designed for demanding bonding applications. Featuring a 500 μm black conformable acrylic core and a modified acrylic adhesive system, it provides strong, durable bonding across a wide range of surfaces—including most powder-coated substrates, glass, metals, and plastics. Its viscoelastic properties allow it to absorb stress, fill gaps, and maintain reliable long-term adhesion, making it an excellent alternative to mechanical fasteners such as screws, rivets, welds, and liquid adhesives.

Key Features & Benefits

• High-strength, permanent bonding with long-term durability.
• Viscoelastic acrylic foam core delivers excellent conformability and stress dissipation.
• Bonds well to high, medium, and low surface energy substrates—including powder-coated surfaces.
• Eliminates mechanical fasteners for cleaner, more aesthetic end products.
• Black color ensures discreet application in shadow lines and structural joints.
• Resistant to moisture, temperature fluctuations, and environmental stress.
• Enables use of thinner, lighter, and dissimilar materials in modern designs.
• PFAS/PFOS-free for safer, more sustainable bonding solutions.
