Tape 4646, Dark Gray

3M™ VHB™ Tape 4646: A High-Performance Adhesive Solution
This dark gray, 0.6 mm (0.025 in) tape features a firm foam core and exceptional high-temperature resistance. Designed to replace rivets, welds, and screws, it offers a fast, easy-to-use, and permanent bonding solution with outstanding strength and long-term durability. Its viscoelasticity and powerful bonding capabilities provide design flexibility and enable adhesion to a wide range of surfaces.

Convenience with Extreme Adhesive Power

3M™ VHB™ Tape consists of a durable acrylic adhesive with viscoelastic properties. This creates an extraordinarily strong, double-sided foam tape that bonds to substrates such as aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete. These tapes deliver excellent shear strength, conformability, surface adhesion, and temperature resistance.

Widely used across various industries, including transportation, appliances, electronics, construction, signage, and general manufacturing, the tape reliably bonds materials with strength and speed for permanent applications.

Recommended Applications

• High-energy surface (HSE) metal, glass, and substrates
• Decorative materials and trims
• Nameplates and logos
• Electronic displays
• Panel-to-frame assemblies
• Reinforcements to panels

Dream, Design, and Deliver with the 3M™ VHB™ 4950 Family

3M™ VHB™ Tape 4646 belongs to the 4950 family of 3M™ VHB™ Tapes. This family features a general-purpose adhesive on both sides of a firm foam core. Designed for excellent adhesion to metals, glass, and other high-energy surface materials, the tape is ideal for applications such as reinforcement bonding, sealing polycarbonate lenses over LCDs, securing windows to painted control panels, and mounting vinyl wiring ducts and channels.

An Unconventional Foam Tape

3M™ VHB™ Tapes were invented in 1980 as the first of their kind, combining conformability with strong, permanent bonding. This innovative design results in a family of tapes that adhere to a wide range of substrates.

3M™ VHB™ Tape is a proven alternative to screws, rivets, welds, and other mechanical fasteners. From skyscrapers and mobile phones to electronic road signs, refrigerators, and architectural windows, this tape is relied upon for one or more steps in assembly, mounting, fastening, and sealing processes. It provides consistent bonding, exceptional durability, and excellent resistance to solvents and moisture.

3M backs all its products with design guidance and technical support, ensuring you have the assistance you need.

Proven Reliability of 3M™ VHB™ Tapes

3M™ VHB™ Tape offers durable bonding that outperforms mechanical fasteners. It enhances the aesthetic of finished products by eliminating rivets and screws while providing immediate handling strength. Bonding with 3M™ VHB™ Tape is often faster than drilling, fastening, or using liquid adhesives.

This versatile tape can be used indoors or outdoors for applications such as window, door, and sign assembly, electronics, construction, and numerous industrial uses. Resistant to chemicals, UV rays, and temperature extremes, it withstands the heat of Dubai and the cold of Canada. Its unique acrylic chemistry is highly durable and reliable, making it a tape you can trust.
