Anti-Paint FUYA 7009 Series Products
Product Profile
conformal coating is a special formula of paint, used to protect circuit boards and their related equipment from environmental erosion, can effectively protect all kinds of electronic circuit boards, play the role of moisture-proof, anti-corrosion, anti-static, anti-salt fog, thereby improving and prolonging their service life, to ensure the safety and reliability of use. Three kinds of anti-paint, the application environment is not the same, the common conformal coating is acrylic conformal coating, polyurethane conformal coating, silicone conformal coating.

3. Suggested methodology
Brush painting method: manual operation, easy to use, can produce excellent coating effect on smooth surface;
Spraying method: spray tank products can be easily used in maintenance and small-scale production, spray gun suitable for large gauge production, but these two spraying methods for operation accuracy requirements, and may produce shadows (the lower part of the components are not coated with conformal coating place)
Immersion method: Immersion can ensure complete film mulching and will not cause waste of materials due to over-spraying;
Equipment selective coating: coating accurate and not waste material, suitable for mass coating, but the coating equipment requirements are high, the most suitable for mass production of circuit board coating.
