When Do You Need Conductive vs. Conformal Coatings?
Conductive and conformal coatings serve different purposes. Conductive coatings provide electrical conductivity and EMI/RFI shielding, while conformal coatings electrically insulate and protect electronics from moisture, dust, chemicals, and corrosion.
Conductive Coating
EMI/RFI shielding: Blocks electromagnetic and radio frequency interference to improve device performance and ensure EMC compliance.
Electrical conductivity: Creates a conductive surface that enables electrical current flow using materials like silver, copper, or nickel.
Plastic enclosures: Applied to plastic housings to add EMI shielding without the need for metal enclosures.
Grounding: Establishes reliable grounding paths to reduce electrical noise and improve signal integrity.
Conformal Coating
Moisture protection: Seals electronic components against moisture, humidity, and condensation to prevent damage.
Electrical insulation: Provides a non-conductive barrier that prevents short circuits and electrical leakage between components.
PCBs: Protects printed circuit boards from dust, chemicals, and environmental contaminants while extending their lifespan.
Corrosion prevention: Shields electronic assemblies from corrosion caused by moisture, salt, and harsh environmental conditions.
Selecting the correct coating depends on your product’s performance requirements, operating environment, and regulatory standards.
What is Conductive Painting?
Conductive coating is a specialized finishing process that improves electronic component performance by providing electrical conductivity, shielding, and long-term protection.
Conductive paint allows electricity to flow through surfaces by combining conductive pigments with a resin binder. MG Chemicals offers a variety of conductive paints, with fillers like carbon, nickel flake, silver-coated copper, and silver flake, each designed for different levels of conductivity and corrosion resistance. In partnership with Versatile Spray Painting (VSP), MG Chemicals provides top-tier paints, while VSP handles expert application services for precision and quality.
