1. Application of 3M double sided adhesive tape in different fields
3M double-sided tape can be divided into many types according to the material classification, so the application range and method of different materials will be different. The following is the use methods of 3M double-sided adhesive tape, pet double-sided adhesive tape, non-woven double-sided adhesive tape and hot-melt adhesive as reference:
1) Double sided adhesive for foam substrate
It is suitable for the bonding of air conditioner, office furniture and communication products. VHb double-sided adhesive tape can replace screw fixing design to make the product more beautiful. It has the advantages of softness, good adhesion, good initial adhesion and adhesion, good solvent resistance and ultraviolet resistance. The general thickness is about 0.4-1.0 mm. The short-term temperature resistance reaches 130-150 ℃, and the long-term temperature resistance reaches 80-93 ℃.
2) Double sided adhesive for pet substrate
Generally, the long-term temperature resistance reaches 100-125 ℃, and the short-term temperature resistance reaches 150-200 ℃. The thickness is generally 0.048-0.2mm, which is suitable for the bonding of nameplates, LCD, decorations and decorative parts.
3) Double sided adhesive without substrate
It has excellent adhesion effect, excellent waterproof performance, good processing performance and good temperature resistance. The short-term temperature resistance can reach 204-230 ℃, and the long-term temperature resistance can reach 120-145 ℃. The thickness is generally about 0.05-0.13mm, which is suitable for the bonding of nameplates, panels and decorative parts.
4) Double sided adhesive for nonwoven fabric substrate
It has good viscosity and processability. Generally, the long-term temperature resistance can reach 70-80 ℃, and the short-term temperature resistance can reach 100-120 ℃. The thickness is generally about 0.08-0.15mm. It is suitable for the lamination of nameplates and plastics, automobiles, mobile phones, electrical appliances, sponge, rubber, labels, paper products, toys and other industries, home appliances and electronic instrument parts assembly, die-cutting double-sided adhesive display lens.

2. How to paste 3M double-sided adhesive tape to make it more sticky?
If you paste it casually according to the general way, it will not achieve the ideal effect, but also not beautiful. If you follow the steps below, you can definitely achieve the ideal connection effect:
1) Firstly, the adhesive surface must be cleaned and dried. Generally, it is recommended to take a mixture of 1:1 IPA (isopropanol) and water with a cloth to wipe the surface. After cleaning, wait for the surface to dry completely.
2) After the cleaning solvent is dried, glue the adhesive tape to the adhesive surface, and apply a pressure of about 15psi (1.05kg/cm2) to 3m double-sided adhesive tape by roller or other means to make it effective.
3) Tear off the tape release paper, and then paste the material to be bonded, and apply 15psi pressure to make it effective. If bubbles need to be removed, the pressure should be increased to the upper limit of the article's tolerance.
4) When pasting, the ideal temperature is 15-38 ℃, not less than 10 ℃.
5) When adhesive tape is bonded, one end should be bonded first and then slowly pressed to the other end to reduce the probability of bubbles.
