JS-380B modified acrylic tri-proof paint

JS-380B modified acrylic tri-proof paint

The three-proof paint is called insulating paint or moisture-proof oil, which is used to protect circuit boards and related equipment from environmental erosion. The three-proof paint has excellent insulation, moisture-proof, anti-leakage, anti-vibration, dust-proof, anti-corrosion, and anti-chemical properties.

Product description

Product model: JS-380B three anti-paint

Main ingredients: polyester acrylic resin


  1. Very low odor, no aromatic hydrocarbon solvents such as benzene, toluene and xylene.
  2. The fast surface drying rate can meet the production needs of customers and improve production efficiency.
  3. It meets safety requirements, and the flame retardant effect reaches ULV-0 level.
  4. It can be used in a wide range of temperatures, stable and sufficient adhesion under -30℃~130℃.
  5. Good compatibility with different types of circuit boards and excellent adhesion.

Applicable process: brushing, dipping, spraying

Application areas: This type of three-proof paint has better adhesion, moisture resistance and solvent resistance than acrylic resin protective coatings, keeping the product with a long service life in harsh marine, automotive, aviation and consumer electronics applications.

Operation instructions:
First, clean the PCBA board. If the surface treatment of the substrate is not good, dust, oil, flux residues (including no-clean flux) on the surface of the substrate will affect the adhesion of the coating film and the substrate. It is also the point where corrosion and mildew of the PCB board will occur in the future. Therefore, in the construction of three anti-paints, the surface treatment of the substrate is very important.
Various processes of spraying, brushing and dipping can be used, and the applicable temperature is -30-130°C. The construction conditions require that the ambient temperature is not less than 15°C and the relative humidity is not more than 75%. Maintain very good ventilation during construction. The thickness of the paint film layer generally depends on the coating method (standard thickness is 25μm). After drying, it will become a paint film, which has the characteristics of good adhesion, good flexibility, and high hardness.
The three-proof paint can be used with JS-400 thinner, and can be applied after mixing evenly during dilution. Users can dilute according to their desired viscosity and film thickness.

Packaging and storage: 5L, 18L, store in a cool place away from light
