MA3100 Acrylic Conformal Coating

MA3100 is an organic, modified acrylic-based, single-component conformal coating that dries quickly. This environmentally benign product emits a low odor due to its solvent composition and serves as a protective layer for printed circuit boards by coating their components. Its properties include excellent insulation, resistance to moisture, dust, corrosion, and mildew, making it ideal for safeguarding electrical systems that require three-proof protection (moisture-proof, dust-proof, anti-corrosion).

Features and benefits

  • One-component transparent, rapid curing at room temperature or heating.
  • Low odor, non-irritating and environmentally friendly.
  • Low viscosity, easy to apply various sizing and spraying processes.
  • Curing to form a tough and wear-resistant surface coating.
  • It has good moisture-proof and earthquake-proof protection properties.
  • Good electrical properties.
  • Excellent adhesion to a variety of substrates.
  • Good insulation resistance and breakdown voltage resistance.
  • Working temperature -40oC~125oC.
  • Comply with VOC emission standards.
  • Comply with EU ROHS and REACH standards.
