Professional-grade double-sided foam tape with acrylic adhesive for permanent bonding. Delivers immediate handling strength as an alternative to rivets, welds, and screws. Suitable for aluminum, steel, plastics, and composites with excellent temperature and moisture resistance.
3M™ VHB™ Tape 4956F is a premium double-sided foam tape engineered for permanent bonding applications across multiple industries. This professional-grade adhesive tape features a multi-purpose acrylic adhesive combined with a conformable foam core, backed by a 5 mil red printed polyethylene film liner, delivering a total thickness of 62 mil (1.6 mm) when applied. The tape provides an exceptional balance of strength, conformability, and adhesion to both high and medium surface energy materials, making it an ideal alternative to traditional mechanical fasteners such as rivets, welds, and screws, as well as liquid adhesives.
The 4956F model excels in demanding applications requiring immediate handling strength without the need for fixture time or cure waiting periods. Its unique acrylic chemistry delivers excellent shear strength and surface adhesion while maintaining superior conformability to irregular surfaces. The tape is specifically formulated to adhere reliably to aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete. With outstanding outdoor durability, the tape resists both extreme high and low temperatures as well as moisture exposure, making it suitable for indoor and outdoor applications.
Commonly utilized across transportation, appliance manufacturing, electronics, construction, sign and display, and general industrial markets, 3M™ VHB™ Tape 4956F enables designers to use thinner, lighter-weight, and dissimilar materials compared to traditional fastening methods. The product is UL GREENGUARD™ and UL GREENGUARD™ Gold Certified, contributing to LEED® credit achievement. With closed-cell acrylic chemistry proven to withstand extreme environments, this tape offers consistent bonding, outstanding durability, and excellent solvent and moisture resistance for long-lasting performance.
