Shenzhen glue manufacturers share the correct operation methods and specifications for spraying three proof paint
Three proof paint, also known as circuit board three proof paint, three proof adhesive, insulation 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.
Three proof paint is a flammable chemical substance that contains some irritating chemicals to the human body. Shenzhen glue manufacturers will introduce how to spray various types of three proof paint in a standardized and safe manner.

After purchasing the three proof paint product, carefully review the product description and precautions, and then prepare the corresponding tools, protective equipment, and devices. Here are the recommended operating methods for Shenzhen glue factory.
1. If a thicker coating is desired, it is best to obtain it by spraying two thinner coatings, and the second layer must be allowed to be applied only after the first layer has completely dried.
2. All coating operations should be carried out under climatic conditions with a temperature not lower than 16 ℃ and a relative humidity not higher than 75%. PCB boards, as composite materials, are prone to moisture absorption. Please clean the circuit board first, and then keep it dry, otherwise the three proof paint will not fully protect it. Before coating, the dust, moisture (moisture) and oil stain on the surface of the object to be coated must be removed. If there is moisture, it is recommended to dry the plate at 60 ° C for 10-15 minutes, and then take it out for spraying after natural cooling in the oven.

3. During the construction process of the three proof paint, high temperatures and open flames should be avoided, and sufficient ventilation conditions should be provided to facilitate the evaporation and rapid curing of solvents in the paint. The cured three proof paint processed parts are basically harmless to the human body. Pay attention to safety and protection before spraying operations, and employees should wear protective masks and gloves.
4. Some products solidify upon contact with moisture in the air during use. The higher the moisture content in the air, the faster the drying and curing of the adhesive layer; The higher the temperature, the faster the curing of the adhesive layer (but not exceeding 80 ℃). Used brushes, spray guns, etc. should be promptly cleaned with specialized cleaning agents for future use.
5. After pouring out the glue from the bottle, clean the glue at the bottle mouth, tighten the bottle cap, and store it in a cool and sealed place. When reusing, if there is a slight peeling phenomenon at the sealing area, it can be removed without affecting normal use.
