3M VHB Double-Sided Acrylic Foam Tape provides permanent bonding via a high-density acrylic foam core. It replaces mechanical fasteners like rivets and screws in industrial and automotive assemblies. The 1.1 mm thick tape operates at temperatures reaching 149°C while resisting water and UV exposure.
Key Features
- Viscoelastic Acrylic Foam: Absorbs vibrations and high-impact energy across the bond line. This stops joined components from rattling or loosening in machinery.
- Waterproof Seal: Creates a permanent barrier against moisture, humidity, and road dust. It prevents surface corrosion between joined parts in wet environments.
- Heat Resistance: Maintains bond integrity at temperatures up to 149°C. The adhesive won't melt or slip during high-heat automotive engine use.
- Mechanical Replacement: Eliminates the need for drilling holes, welding, or using screws. This maintains structural integrity by preventing surface damage and rust spots.
- 1.1 mm Thickness: Distributes stress evenly across the entire surface area. It prevents localized failure common with point-fasteners like bolts or rivets.
Frequently Asked Questions
Is 3M double sided tape waterproof?
The acrylic foam core creates a permanent seal against water and humidity. It maintains adhesion even when submerged or exposed to heavy rain.
How long does 3M VHB tape take to cure?
Initial bond reaches 50% strength after 20 minutes, with full curing at 72 hours. Applying pressure during installation accelerates the initial surface contact.
Can 3M tape be used on car dashboards?
This tape bonds well to high surface energy materials like metal and glass. It may fail on low-energy plastics or textured dashboards without a primer.
