Before ordering, please read the "Product Description & Specs" tab content for more information about this item.
Product Description
3M 4950 VHB Tape is a double-sided tape typically used on metal, glass and high surface energy plastic substrates. It can be used for attaching stiffeners in air conditioners, office furniture, and telecommunications equipment. Also, to bond aluminum skin to steel support of truck, vans, ambulances or to bond architectural signs to frames. The firm foam used in 4950 provides the highest level of foam strength in the 3M VHB family. UL Listing 746C.
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 http://solutions.3m.com/wps/portal/3M/en_US/Adhesives/Tapes/Brands/3M-VHB-Tape/ for videos showcasing the properties of VHB tape. Country of Origin: United States.
* Multiple cases may be shipped per package in order to minimize the charge for shipping.

QUESTION: What’s the max weight this can hold?
ANSWER: 3M has two rules of thumb to use for VHB:
1. Use 4 square inches of tape for each 1 pound of weight need to hold up.
2. When choosing the thickness of the tape you need make sure the VHB tape's thickness is at least 1/2 the thickness of the thinner of the two substrates you are bonding to.
Thank you.

Strong Tape
3M 4950 VHB Tape [45 mil / general purpose]
I bought the VHB 4950. I used it to attach my solar panel on the roof of my van. At speeds of 80 mph this tape holds. If someone tried to tear the panel off they would break the panel or tear the roof. The bond is solid and strong. I am very pleased with this product and even did a review on my YouTube channel.

3M 4950 VHB Tape [45 mil / general purpose]
Strongest adhering tape I can find at the moment. 3M actually had a similiar looking white tape that was about 20% stronger. I think it's very strange that it is not available anymore.

Product as described, great price, and fast shipping.
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.
acrylic
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.
silicone
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
Lower gauge gloves are heavier - have thicker construction, fewer stiches knitted per inch and offer less dexterity.
Higher gauge gloves are lighter - have thinner/finer construction, more stitches knitted per inch and offer more dexterity.
Gloves offered typically runs from 7 to 18 (12 and 13 are in the middle of the scale).
