3M™ VHB™ Tape 4941
The 3M™ VHB™ Tape 4941 is a fast and easy use permanent bonding, gray, 0.045 in (1.1 mm) thin tape that provides high strength and long term durability. Its virtually invisible fastening keeps surfaces smooth that makes it an ideal replacement for mechanical fasteners like rivets, welds, and screws, as well as liquid adhesives.
Due to its multi purpose acrylic adhesive with a conformable foam core, it provides exceptional bonding strength and design flexibility. It adheres to a wide range of substrates, including metals, glass, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete.
- High-strength permanent bonding replaces screws, rivets, welding and liquid adhesives for a cleaner and stronger assembly.
- Conformable acrylic foam core easily adapts to irregular and uneven surfaces for maximum surface contact.
- Strong adhesion to metals, glass, painted surfaces and many plastics, making it suitable for a wide range of industrial applications.
- Provides a durable seal against water, moisture, dust and environmental contaminants.
- Pressure-sensitive adhesive delivers immediate handling strength, helping speed up production and assembly.
- Designed for indoor and outdoor use with outstanding resistance to UV exposure, weathering and temperature changes.
- Reduces manufacturing time and costs by eliminating drilling, grinding, welding and mechanical fastening.
- Ideal for bonding dissimilar materials while maintaining a clean, smooth and professional appearance.
- 1.1 mm conformable foam helps absorb vibration, impact and thermal expansion for long-term reliability.
