The use rate of three-proof glue in the electronics industry is very high. Different regions and different manufacturers will give it different names according to its use requirements and characteristics. For example: road board protective glue, coating glue, moisture-proof oil, coating glue, insulating glue, three-proof oil, common coating and so on.

After the three-proof adhesive is used, there will be a layer of film, and this film is a very thin protective layer of electronic circuits and components. It can enhance the moisture-proof and anti-fouling ability of electronic circuits and components, and can also prevent solder joints and conductors from being eroded.In environments such as chemical, vibration, salt spray, humidity and high temperature, the circuit board is likely to suffer from corrosion, softening, deformation, mildew and other problems, resulting in circuit board failure. At this time, three-proof glue is applied to the surface of the circuit board to form a three-proof protective film. It can effectively isolate the circuit board, and can protect the circuit from corrosion and damage in harsh environments, thereby improving the reliability of the circuit board, increasing its safety factor, and ensuring its service life.

What are the characteristics of the three-proof glue?

① The fluidity is good, it can flow well, and it is easy to use;

② After the coating glue is cured, it will form a soft (or a certain hardness) transparent (or colored) elastoplastic coating, which will not be corrosive to the material;

③Excellent weathering resistance and high and low temperature resistance, the performance changes little in the range of -50℃～+200℃.

④ The material has high adhesion strength and excellent insulation and flame retardant properties;

⑤ Some coating materials (softer hardness) have good ability to relieve stress.

Since the three-proof glue plays such a big role in protecting electronic components, it is undoubtedly very important to choose a regular and reliable manufacturer, so that it is more reliable to use.
