ULTRA HIGH BOND DOUBLE COATED ACRYLIC TAPE
Available in 25 mil and 45 mil thicknesses for permanent structural bonding applications.
DCUHB Ultra High Bond Double Coated Acrylic Tape is a structural-grade bonding tape made with a solid acrylic polymer core and coated on both sides with a uniform high-tack acrylic adhesive. It provides a strong, permanent bond between a wide variety of substrates, including glass, select plastics, composites, sealed wood, metals, and painted metals.
This tape is designed for demanding industrial and structural assembly applications where mechanical fasteners such as welding, rivets, bolts, screws, and liquid cementing may be replaced. Its solid acrylic core offers superior strength while remaining flexible, moldable, compressible, and conformable to intricate shapes.
DC-UHB is available in two thickness options: DCUHB25, 25 mil x 72 yards, for thinner structural bond lines and strong metal-to-metal bonding, and DCUHB45, 45 mil x 36 yards, for applications requiring greater cushioning, vibration dampening, and conformability.

Application Tips
- Apply only to clean, dry, oil-free, and properly prepared surfaces.
- Make sure surfaces are free from dust, grease, moisture, and loose particles before application.
- Avoid touching or contaminating the adhesive surface after removing the liner.
- Apply firm, even pressure across the full bonding area to ensure maximum adhesive contact.
- Allow proper dwell time for the adhesive to develop maximum bond strength.
- For best results, test the tape on your specific surface before full application.
