MA3102 Acrylic Conformal Coating

MA3102 is a one-component, quick-drying, moisture-proof and insulating conformal coating for circuit boards. It is a conformal coating made of modified acrylic resin and corresponding environmentally friendly solvents. It is suitable for gluing printed circuit boards. Insulate electrical equipment, connections, switch panels, wiring boards, etc., and use three-proof protective coatings for the life of printed circuit components. Easy to spray, brush, and dip into, and can be cured using room temperature or heat. In the environment of -40°C~125°C, this product has stable elasticity and excellent dielectric properties, waterproofness, earthquake resistance, weather resistance, pollution resistance, UV resistance, and moisture-proof insulation. It fluoresces under ultraviolet light and is easy to repair. It can be soldered through at soldering iron temperature for easy repair.
