How to Make 3 M Tape Sticky Again
Or how to continue your headphones hanger from falling off?
What is a 3M VHB Record?
The 3M VHB Tape is a two-sided adhesive tape produced by 3M. VHB stands for "Very High Bail". Every bit the name implies, information technology is a double sided tape with industrial strength. 3M has a catalog of VHB tapes that can arrange different needs – from articulate double-sided tapes to heavy-duty double-sided tapes for cars that are able to withstand extreme estrus and cold.

This incredible slice of invention is also a popular solution for applications where aesthetics are important. With the adhesive tapes, y'all can practice without the ugly screws or clamps that volition alter the beauty of the product.
Headphone Stand Mount
In our context, the 3M VHB Tape is commonly seen on headphone stand up mount. The headphone stand mountain comes with a double-sided mounting record that allows the headphone stand to be mounted on the undersides or sides of the tabular array.
Headphones owners who want a make clean and easy way to go along abroad their headphone will choose the headphone stand mount over the usual headphone stand up.

Pitfall
Although the 3M VHB Tape offers an aesthetically pleasing manner to mount the headphone stand, you take to be stringent in the style y'all utilise the 3M VHB Record. Very often, negligence in the application procedure will effect in the post-obit complaint – the tape does non stick long enough.
Every bit with nearly reviews on the internet, y'all simply get to read one side of the story but it is clear that the 3M VHB Tape is no magic bullet.
The expert news is that you tin greatly meliorate the adhesiveness of the 3M VHB Tape. We have compiled a stride-past-footstep checklist for maximizing the strength of your 3M VHB Tape.
Checklist for achieving ultimate bond strength of the 3M VHB Record
one. Preparing the surface
i.1 Make certain the surface is clean
A rudimentary dominion for skilful tape bond is checking the cleanliness of the surface that you will be applying information technology on. You should utilise rubbing alcohol to clean the surface. Make sure information technology is cleared of any specks of dirt and as well the surface must be dry.
If the surface is greasy, y'all will need a stronger solution like the 3M Citrus Base Cleaner to cut the oil. Finish off with the rubbing booze to ensure all remainder are removed.
1.2 Add micro-chafe
When we add chafe to the surface, nosotros are increasing the surface area for boosted adhesion. This is very effective for painted and plastic surface. The fob is to achieve micro abrasion and not deep cuts because the surface still needs to remain flat. You can use the Scotch-Brite® Manus Pads to attain the right amount of abrasion.
Tip 1: Use round motion instead of linear motion to increase the amount of micro-scratches.
Tip 2: Not all adhesive tape needs micro-abrasion. 3M VHB 4932 and 4952 are suited for glossy surfaces.
1.three Bank check texture of the surface
Surfaces that are crude, porous or fibered are the worst to apply the 3M VHB Record on. But if you insist on applying the tape onto them, you will demand an extra pace of grooming – sealing. This volition assist unify the surface to increase bail force.
Common sealing materials are paint, varnish and other hard surface coatings. Yous can also use Fast drying 3M™ Safety and Vinyl Spray fourscore.
1.iv Check nature of the surface
Hydrophilic(water-loving)
Water-loving surface affects the adhesive bail immovability in high humidity environment. The water vapor weaken the tape bail and the adhesion force.
Solution: Use rubbing alcohol solutions that comes with silane coupling agents to reduce the water-loving tendency of the surface.
Examples of hydrophilic surfaces:
- Glass
- Stone
- Ceramic
1.5 Oxidation
Surfaces that are susceptible to oxidation will weaken the record bail too.
Solution: Using a sealer cloth will help improve the adhesiveness.
Examples of such surfaces:
- Copper
- Contumely
- Statuary
1.6 Priming
This is an additional pace that you can take to raise the adhesiveness. By priming a surface, you are substantially creating a new surface to promote better adhesion. Yet, in that location is no one-size-fits-all primer. Expect at the tabular array below to notice out the best primer for dissimilar surface.
2. Applying the tape
2.one Maximise adhesive-to-surface Ratio
The greater the adhesive-to-surface contact, the stronger the adhesiveness. To maximise this adhesive-to-surface ratio, yous demand to use the sufficient amount of pressure. This volition help ameliorate bond forcefulness.
The recommended strength is at least 15 psi (100 kPa). Utilize a roller to roll downward the record. Even so, if a roller is not at your disposal, I find that using your hand and body weight is enough to use good amount of pressure.
3. Let it rest
3.1 Don't rush it
After the tape is properly applied, the record needs time to bond with the surface. Bond force increases as the agglutinative flows onto the surface. Impatient users who did not allow the tape to balance sufficiently will observe their tape quickly peeling off.
iii.2 Increase the temperature (Optional)
The higher the temperature, the faster the record will reach the ultimate bond strength. To accomplish 50% of the maximum bond strength in room temperature, it will accept approximately 20 minutes.
Below you lot can see the nautical chart for the correlation betwixt time and temperature to achieve ultimate bond force.

Conclusion
Equally you tin can see, applying the 3M VHB Tape is not directly forwards but it is not exactly rocket science. To be frank, if I had not done the enquiry, I would have blamed the adhesiveness problem squarely on the manufacturer.
Then, the next fourth dimension your friends complain about their 3M VHB Tape peeling off, send them this commodity before they go off ranting on the forum about poor build quality.
Where to purchase 3M VHB Tape?
You tin can hands buy them at Amazon or any other hardware shop.
