Adhesive manufacturer, manual brushing method and process for three proof paint
hree proof paint, also known as circuit board three proof paint, three proof adhesive, protective paint, insulation paint, moisture-proof paint, covering adhesive, coating adhesive, moisture-proof oil, common film coating, conformal coating, electronic coating material, etc., is called normal coating in English. Three proof paint is a type of single component transparent or semi transparent adhesive that can be cured at room temperature, by heating, or by ultraviolet light. It has the characteristics of low viscosity, high transparency, excellent insulation performance, high and low temperature resistance, and easy use. Three proof paint is mainly used for covering and coating the surface of various assembled electronic circuit boards, providing protection for the circuit boards and achieving multiple protections such as moisture-proof, anti fouling, anti salt spray, insulation, etc., in order to improve product performance, stability, safety, and service life. It can also be used for shallow encapsulation and filling of electronic products.

Many customers experience unsatisfactory results in the application of three proof paint by hand due to improper operation methods. Mainly manifested in uneven application of the three proof paint, uneven surface, unsightly appearance, and omissions. For these situations, the engineer from the three proof paint manufacturer will tell you how to apply the three proof paint? How thick is the brush? How many times do you brush? What brush should I use?
The first brushing tool used should be a wool brush or a brush brush (small parts must be brushed with a brush). After brushing, the brush should be cleaned and dried in a timely manner. If the residual three proof paint on the brush is too thick during the brushing process, a new wool brush should be replaced in a timely manner. The thickness of the three proof paint coating should be applied according to the protection requirements of the product. For high protection requirements, it can be applied thicker, while for low protection requirements, it can be applied thinner. In general, a brushing thickness of 0.1-0.3mm is sufficient. In general, a wool brush should be brushed once or twice on the circuit board to achieve the required thickness. The brushing should be uniform, and the number of brushing times can be determined according to actual needs. Some small components or areas on the circuit board that have not been brushed can be brushed and repaired with a brush.
