Common Problems Of 3M adhesive tape Storage, Transportation, Use And Maintenance

1. What is the reason for the aging (deterioration) of 3M adhesive tape?
Factors that cause tape aging are: oxygen, ultraviolet (sunlight), metals (especially brass or rust), bleaching agents, plasticizers.Under the long-term influence of the above factors, the tape will deteriorate, soften, solidify and lose its viscosity.

2. How to tear the 3M adhesive tape without causing residual glue?
A. When the peel is removed at an Angle of about 90°, the measured peeling force is small and it is less likely to cause residual glue.
B. The removal speed should be appropriately slow to make residual glue less likely.
C. The operating environment of 15 ~ 38℃ and the attached surface temperature are less likely to cause adhesive residue, and the lower temperature part is better.

3. What is the service life and expiry date of the 3M adhesive tape?
In terms of a tape supplier, all the tape as a base material coating and pressure sensitive adhesive, pressure sensitive adhesive for viscoelastic polymer, in materials science, all material under oxygen and ultraviolet radiation, dust, solvent, and moisture, etc., will be more or less affected, so tape producers will give suggest the use of appropriate deadline and storage environment and conditions, packing gauge fan, etc.,To maintain its quality and performance.

4. Why do you sometimes find color difference between 3M adhesive tape rolls?
The reason for the color difference of the tape is that the lattice arrangement of the polymer substrate in the extrusion molding and the polymer crystal arrangement of the pressure sensitive adhesive will have a little difference and affect the hue. The slight difference in the thickness of the pressure sensitive adhesive and the size of the tension of the tape winding will also affect the hue of the tape, which is caused by the color difference after stacked layer by layer.But the characteristic value of the substrate and pressure sensitive adhesive is still based on its basic physical properties.
