Description

High-Strength Structural Bonding Tape

The 3M VHB Tape 4941 is a high-performance grey acrylic foam tape designed to provide structural-level bonding strength in demanding industrial and commercial applications. Its 1.1mm conformable foam core and pressure-sensitive acrylic adhesive deliver exceptional holding power and durability, making it a trusted choice for replacing mechanical fasteners such as rivets, screws, and welds.

Exceptional Adhesion and Durability

Formulated to bond a wide range of high and medium surface energy materials, including metals, glass, and plastics, 3M™ VHB™ 4941 offers excellent plasticiser resistance and superior adhesion stability over time. The tape creates permanent, vibration-dampening bonds that remain secure under thermal expansion, mechanical stress, and environmental exposure.

Outstanding Environmental and Chemical Resistance

This high-performance adhesive tape is engineered to withstand UV exposure, moisture, solvents, and fluctuating temperatures. With a continuous service temperature of up to 149°C, it ensures long-term performance in both indoor and outdoor environments, including industrial, construction, and transportation applications.

Enhanced Structural Integrity

The viscoelastic foam core evenly distributes load stress and compensates for surface irregularities, providing flexibility and energy absorption during dynamic loads. This allows for the creation of smooth, aesthetically pleasing joints without drilling, welding, or the use of visible fasteners.

Versatile Industrial Applications

3M™ VHB™ 4941 is ideal for panel-to-frame assembly, stiffener bonding, and mounting decorative trims, logos, nameplates, and displays. It is widely used across industries such as metalworking, signage, appliances, electronics, construction, and transportation.
