With the progress of science and technology, double-sided adhesive tape is more and more widely used in life. When we choose double-sided adhesive, we often encounter the problem of not knowing how to choose the right one for ourselves. There are also many problems, such as the clear test is good (hand test), the stickiness is very strong, but sticking to the product will still rise and fall off, and so on. Now I have these problems. Through my personal understanding and application of double-sided adhesive, I express my personal opinion. If there is any improper, please see the official for more advice.

For the double-sided adhesive Xiaobai, the simplest and intuitive test method for the adhesion of double-sided adhesive is to use the hand. The adhesive force of the hand of the double-sided adhesive can be used to determine whether the adhesive is OK. In fact, this is wrong. Everyone's hands are different. Some people's hands are dry and some people's hands are sweaty. They all have different feelings.

1： Different material problems.

The surface energy (dyne value) of different materials is different, which will affect the adhesive effect. The common surfaces of stickers in life are:

Plastics: PP, PET, PS, PVC, ABS, rubber, silicone, etc

Metal: stainless steel, iron, aluminum, copper

Other categories: paint, baking varnish, ink, hand oil, rubber oil, special paper, leather fabric, ceramics, wood

2、 Environmental factors

Double-sided adhesive is sensitive to the environment, especially some special environments. Temperature and humidity have an impact. All kinds of chemical oils. When pasting, the surface must be clean and dry, without oil and water.

3、 Plasticizer factor

As mentioned earlier, different materials can make different surfaces. Also, different materials contain certain plasticizers, which is also an important factor affecting the viscosity of products.

4、 Construction factors

All double-sided adhesive must be pasted in strict accordance with the construction requirements when being used. After the binding, a certain pressure shall be applied to make the adhesive fully adhere to the adhesive.

5、 Product expired or improperly stored

Double-sided adhesive is exposed for a long time, exposed to the sun, and stored in a high temperature or high humidity environment for a long time. The storage time exceeds the shelf life, etc.
