Product Description

3M 4941 VHB Tape is a double-sided tape which utilizes a multi-purpose acrylic adhesive on both sides of conformable foam. The adhesive provides excellent adhesion to a broad range of high and medium surface energy substrates including metals, glass, and a wide variety of plastics, as well as plasticized vinyl. The conformable foam provides good contact, even with mismatched substrates. Application uses include ABS support structure bonding, aluminum floor bonding, bonding door kick & seal plate, bonding glass to a metal oven door, bonding muntin bars to glass, bus body side panel bonding, channel stiffener bonding on truck bodies, commercial vehicle roof vent attachment, commercial vehicle trim attachment, extruded plastic channel bonding, interior rail car construction, nameplate attachment on commercial vehicles, rail car bonding metal stiffeners, rail car light cover attachment, roof bow bonding on truck bodies, side panel bonding on commercial trailers, stack unit support bracket bonding, trim fairing bonding on truck cab exteriors and truck body nameplate bonding. If trying to bond to more porous substrates such as granite or marble 3M 4941 would be the recommended VHB to go with along with their 3M 94 primer product first on both surfaces bonding to.

3M VHB Tape provides the convenience and simplicity of a tape fastener and are ideal for use in many interior and exterior structural bonding applications. In many situations, they can replace rivets, spot welds, liquid adhesives, and other permanent fasteners. These VHB tapes are made with an acrylic foam which is viscoelastic in nature. This gives the foam energy absorbing and stress relaxing properties which provides these tapes with their unique characteristics. The acrylic chemistry provides outstanding durability performance and the tapes have excellent durability and excellent solvent and moisture resistance. See for videos showcasing the properties of VHB tape. Made in the U.S.

* Multiple cases may be shipped per package in order to minimize the charge for shipping.

Nominal Tape Widths vs Actual Widths

Nominal vs. Actual Widths Zoom In

Tape rolls are cut to standard tape industry metric widths of approx. 24mm per 1-inch of nominal width ordered. As a result ACTUAL tape widths are normally 5% narrower than the NOMINAL width shown in inches. Examples:

  • 1" Nominal width = 15/16" (24mm) Actual width
  • 2" Nominal width = 1-7/8" (48mm) Actual width
  • 3" Nominal width = 2-13/16" (72mm) Actual width

Note that tape rolls are NOT guaranteed to be splice-free.

Excellent product, easy application.
3M 4941 VHB Tape [45 mil / multi purpose]
Excellent product, easy application.
3M 4941 VHB Tape [45 mil / multi purpose]
Made in the USA
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
natural rubber
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
zinc oxide
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
