Heavy-duty double-sided tape is useful in a wide range of construction scenarios, but no tool is perfect for every job. Sometimes, adhesive tape doesn’t stick.To get more news about Double Sided Glazing Tape, you can visit senpinghz.com official website.
It’s easy to assume the tape itself is to blame, but truth be told, there are some other usual suspects to consider first. Here are the 8 most common reasons your double-sided tape won’t stick and how to prevent tape failure.
- Failure to Test
We get it. The package label made lofty promises, but generally speaking, adhesive testing should always be done before using double-sided tape.
Not all double-sided tapes are created equal.
Maybe the one you chose isn’t aggressive enough and it fell off. Or, perhaps, it’s too aggressive and caused damage to the surface it was applied to. When in doubt, test the adhesive first to prevent tape failure.
- Temperature Tape Failure
Carefully factor in the temperature. Are both the tape and the surface at least 18ºC/65ºF? The tackiness of the adhesive tape is very temperature-dependent, and the colder the conditions, the weaker the bond will be. And on the flip side, extremely high temperatures can cause the adhesive to melt and lose its strength.
If you must work at lower temperatures, then use a temperature-sensitive double-sided tape specifically designed for colder climates.
- Dirty Surface
Traces of dust, dirt, grease, and even the slightest hint of moisture before bonding will contaminate the adhesive surface and act as a barrier between the two.
- UV Exposure
Prolonged exposure to ultraviolet light can cause certain chemical materials (such as natural and some synthetic rubbers as well as polyethylene) to become hard and brittle. Absolutely not the qualities you want in a tape that needs to hold for any duration in a particular application.
If the area where you will be using the tape sees above-average UV exposure, you may need to consider a different tool for the job.
- Chemical Migration
Liquids such as oils, plasticizers, and dyes are a lighter weight material and can therefore easily “move” from the product (the surface) to be absorbed by any adjacent material (the tape). This movement is known as “migration.”
For example, consider PVC: plasticized to provide flexibility, it is a lower-cost, lower-molecular weight material. If a typical pressure-sensitive adhesive is applied to PVC and allowed to remain in place for a prolonged period, the plasticizer will migrate from the PVC surface into the pressure-sensitive adhesive; making the glue a gummy mess.
