Three-proof paint is a kind of paint commonly used in our daily life. This is a written name, but there are many other names in the outside world, such as three-proof glue, moisture-proof glue and insulating glue. The three-proof paint is actually a specially formulated paint, which is mainly used to protect the circuit and related equipment from environmental erosion, so as to improve the service life of the circuit board and used to determine the safety and reliability of these electrical equipment.

In real life, circuit boards often cause corrosion and softening due to chemistry, vibration, high dust and other environments. These are the problems we often encounter in life, and it is precisely because of these problems that often lead to wire short circuit failures. The three-proof paint is mainly used to apply on the surface of the circuit board, so that a protective film of three-layer protection can be formed. The three-proof paint mainly refers to moisture, mildew and salt spray. The use of three-proof paint can effectively protect the wiring board from being eroded and destroyed. Of course, it can also improve the reliability of the wiring board. We can also be safer in the process of use, which also increases the service life of electrical appliances invisibly.

In fact, the three-proof paint can also be used to prevent leakage, which allows higher power and closer spacing between the printed boards, thus used to meet the purpose of miniaturization of components. The main purpose of the three anti-paint is to prevent some adverse environmental factors from damaging the electric board, and to reduce the decline of the electronic operation performance to a minimum.

Many coating adhesives have been produced in daily use, but these coating adhesives cannot resist the adverse effects around them, and most of these adverse effects are cumulative, so the general coating adhesives are not very good.

Note on the use of three anti-paint:

1. There is no stirring before use, or there is no layering of pigments and fillers during storage, which leads to curing failure;

2. Changes in the ambient temperature lead to changes in the curing speed and fluidity of the compound;

3. Inaccurate weighing, uneven mixing, and incomplete curing of the cured product due to temperature or time;

4. After opening, the sealing is not good enough to cause moisture absorption and crystallization;

5. If the amount of compounded rubber is too large or the service life is extended too long, a "brittle" occurs;

6. Evaluation of product changes due to moisture during curing;

7. Apparent curing failure affected by the treatment of bubbles on the surface of the cured product;

8. The light-colored cured product will change color due to the curing temperature, ultraviolet light and other conditions;

9. Electrical engineers and chemical engineers fail to design accelerated destructive aging life experiments according to the characteristics of A/B adhesives and the needs of electrical products;

10. Evaluation of various changes in the effect of changes in curing temperature on the curing performance of the material;

11. The evaluation of the damage of the material to the vacuum system, or the influence of the stability of the vacuum system on the quality;

The above is all about the three anti-paint function, I hope to help you! Welcome to consult, we will serve you wholeheartedly!
