Three proofing lacquer also called PCB electronic circuit board extend, overburden oil, waterproof glue peso, JueYuanQi, moistureproof lacquer, anti-corrosion coatings, anticorrosive paint, waterproof, salt fog lacquer, dustproof paint, paint, the beatles overburden paint protection, three - such as glue, had used anti-corrosion paint of PCB a waterproof, moistureproof, dustproof "three proofing" performance and cold and hot shock resistance, ageing resistance, resistance to radiation, salt-fog resistant, ozone and corrosion resistance vibration, good flexibility, good adhesion, such as performance, therefore, very extensive.

Initial anti-corrosion paint applies only to high-tech fields of printed circuit board. Since electronic devices are widely applied in daily life, so now consumers pay more and more attention to product quality and reliability, the use of anti-corrosion paint coated can make producers commonness effective improve product quality, reduce the penetration year-period warranty fault expenses.

Typical USES include the following areas:

1, civil and commercial application

Anti-corrosion paint (common coated) for household appliances in the electronic circuits provide protection, make they can resist:

(1) water and detergent (washing machine, dishwasher, sanitary ware products, outdoor electronic LED screen)

(2) the external adverse environment (display, security, fire alarm device etc.)

(3) chemicals (air conditioning, dryer)

(4) office and home of pests (computer, induction cooker)

(5) all other need three proofing protection of circuit board

2, automobile industry

Automobile industry requirements anti-corrosion paint protection circuit from several situations, such as: the harm of gasoline evaporation content, salt fog/brake fluid, etc. The application of electronic systems in automobile continuously growing rapidly, so using three proofing lacquer has become ensure automotive electronics achieve long-term reliability basic requirements.

3, aerospace

Due to the particularity of the use environment, aviation, spaceflight environment on electronic equipment is strict, especially in rapid compression, decompression conditions, we should still remain good circuit performance. Three proofing lacquer of changeover stability so widely used.

4, navigation

Whether the fresh water or salt water, both will have Marine equipment of electrical lines harm. Use anti-corrosion paint can maximize the protection on the surface and submerged and underwater equipment.

5, medical

Anti-corrosion paint can protect electronic equipment from external chemicals and special use environment of erosion, ensure its continuing stability.
