How to choose 3M double-sided adhesive correctly? Below, I will introduce to you that 3M double-sided adhesive is widely used in products such as computers, mobile phones, communications, household appliances, audiovisual equipment, and cars. You can use it to

Please refer to the following for the selection of product and environmental requirements for the application:
1. Foam based double-sided adhesive has the characteristics of softness, good adhesion, good initial and holding adhesion, good solvent resistance and UV resistance, with a general thickness of 0.4-1.0mm and short-term temperature resistance of 130-150

℃, long-term temperature resistance of 80-93 ℃, suitable for bonding air conditioners, work furniture, and communication products, can replace screw fixation planning, making the product more beautiful.
2. Hot melt adhesive film has outstanding consistency, uniform adhesive thickness, no solvents, easy processing, and excellent adhesion to many objects. The thickness is 0.1mm and the color is semi transparent

/Amber color, hot melt softening temperature 116-123 ℃. Suitable for bonding nameplates, plastics, and hardware components; Bonding on the surface of uneven objects can also achieve good results. It is recommended to initiate bonding

The conditions are: temperature 132-138 ℃, bonding time 1-2 seconds, and pressure 10-20 pounds per square inch.

Correct operation of 3M double-sided tape
When bonding 3M double-sided adhesive, the following methods need to be followed to achieve enhanced bonding effect:
1. First, the adhesive surface must be cleaned and dried. It is generally recommended to use a cloth dipped in a mixture of 1:1IPA (isopropanol) and water to wipe and clean the surface, and wait for the surface to completely dry.
2. After the cleaning solvent dries, apply the tape to the surface of the adhesive and apply a pressure of about 15PSI (1.05 kg/square centimeter) using a roller or other method to effectively bond it.
3. Tear off the release paper from the adhesive tape, then apply the required adhesive material and apply the same pressure of 15PSI to ensure effective adhesion. If bubbles need to be removed, the pressure should be increased to make the item acceptable

The limit is the upper limit.
4. The ideal temperature for posting is 15-38 ℃, not lower than 10 ℃.
5. When adhesive tape is used, one end should be first bonded and then slowly pressed to the other end to reduce the probability of bubbles occurring.
The suitable environmental requirements for storing 3M double-sided tape are: temperature is 19-23 ℃ and humidity is 40-60%.

3M double-sided adhesive has excellent adhesion, can prevent falling, and has excellent waterproof function. It has good processing function and temperature resistance, and can withstand temperatures up to 204-230 ℃ in the short term, usually for a long time

The temperature resistance reaches 120-145 ℃, and the thickness is generally about 0.05-0.13mm, suitable for bonding of nameplates, panels, and decorative components.
The double-sided adhesive tape on non-woven fabric substrate has good adhesion 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, suitable for laminating nameplates, plastics, cars, mobile phones, appliances, sponge, rubber, signs, paper products, toys and other professions, as well as assembling and displaying parts for household appliances and electronic instruments

Screen lenses.
