Industrial-grade permanent bonding tape with 62 mil acrylic foam core, 12 inch width, and 72 yard length. Replaces mechanical fasteners with strong, seamless adhesion for dissimilar materials. Temperature rated to 300°F short-term, 200°F long-term. UL GREENGUARD certified.
3M™ VHB™ Tape 4979F is a robust and permanent acrylic bonding solution engineered for challenging industrial applications. This high-performance foam tape adheres quickly and securely to thin, lightweight, and dissimilar materials, offering a versatile alternative to traditional mechanical fastening methods such as rivets, welds, and screws. The advanced pressure-sensitive acrylic adhesive technology delivers strong, long-lasting bonds while creating seamless, aesthetically pleasing joints that maintain surface integrity.
Designed with a conformable acrylic foam core, this tape provides an excellent balance of strength and flexibility, making it ideal for applications where bonded surfaces may expand and contract differentially. The closed-cell acrylic chemistry ensures superior performance in extreme environments and protects against moisture and water ingress, creating a permanent seal for long-term durability. With a 62 mil thickness and polyethylene film liner, the tape is engineered to withstand temperatures up to 300°F (149°C) for short-term use or 200°F (93°C) for long-term applications.
The 12-inch width by 72-yard length format on a 3-inch core provides ample material for industrial bonding projects across multiple industries including appliance assembly, transportation, construction, signage, and electronics. This tape is UL GREENGUARD and UL GREENGUARD Gold Certified, contributing to LEED credits and environmental compliance. By eliminating the need for drilling, grinding, welding, and project cleanup, 3M VHB Tape 4979F delivers significant time and cost savings while improving productivity and reliability in manufacturing operations.
