The 3M™ VHB™ Tape 4979F is a high-strength, double-sided acrylic foam tape engineered for permanent structural bonding in demanding industrial and marine environments. Featuring a black, conformable acrylic foam core, this tape provides exceptional adhesion to a wide range of substrates including metals, painted surfaces, glass, composites, and many plastics.
Designed to replace mechanical fasteners such as screws, rivets, and welds, 3M 4979F delivers long-term durability, vibration resistance, and environmental sealing. Its closed-cell foam structure helps prevent water ingress while maintaining strong bond performance under UV exposure, temperature fluctuations, and marine conditions.
Commonly used on commercial marine vessels, 3M 4979F is ideal for mounting panels, nameplates, trim, signage, insulation components, and equipment housings where a clean appearance and high bond strength are required.
