Three anti rubber does not contain acetone, xylene and other volatile substances, more environmentally friendly and safe.

It is mainly used to form a protective film on electronic circuits and components, enhance the moisture-proof, anti-fouling, anti-mildew, waterproof, and anti-salt spray capabilities of electronic

circuits and components, prevent solder joints and conductors from being corroded, and can also play a role in shielding and eliminating electromagnetic interference, preventing short circuit, and

improving the insulation performance of circuit boards.

In addition, the coated protective film is also conducive to the friction and solvent resistance of the lines and components, and can release the pressure caused by periodic temperature changes.

Suitable for spray, paint, brush, dip and other processes. In order to make the three anti-paint better play the performance, the operation process is a very important link.

Many of our users always feel as if they did not achieve the best protective effect in the imagination when using the three anti-paint, in fact, a large part of the reason is because of the use of the three

anti-paint process, so in order to better achieve the three anti-paint protective effect, we need to understand the use of the three anti-paint process. Let’s take a look at it with the pcb board.

Brush coating – The relatively simple Schniss three anti-adhesive process can achieve excellent coating results on smooth PCB surfaces.

Dip coating – Dip coating ensures complete coating and does not cause waste due to overspraying.

Spraying – Spraying method is the most commonly used coating method in the industry, which is divided into machine automatic spraying and manual spraying. Machine spraying, to achieve

automatic feeding, save labor and material costs, improve production efficiency, to ensure product consistency, product quality, surface spraying effect.

Selective coating film – coating accurate and does not waste material, suitable for large quantities of coating film, but the coating equipment requirements are high. More suitable for large quantities

of film. Use a prepared XY table to reduce cover-ups. When PCB board is sprayed, there are many connectors that do not need spray paint.

Adhesive paper is too slow and there is too much residual glue when torn, you can consider making a combined cover according to the shape, size and position of the connector, positioning with the

mounting hole, and covering the non-spraying part.
