Conformal Coatings

Conformal coatings are essential for protecting electronic devices and extending the lifespan of sensitive equipment. These protective coatings are specifically formulated to safeguard printed circuit boards (PCBs) against harsh environmental conditions such as moisture, salt spray, chemical exposure, and high temperatures.
Samaro offers a complete range of conformal coatings from trusted brands including Dowsil (formerly Dow-Corning), MG Chemicals, and Electrolube—well-known for their high-performance formulations used in electronics, automotive, aerospace, and industrial applications.

Benefits of using a conformal coating
Conformal coatings provide reliable protection against:


Humidity and condensation
Salt mist and corrosion
Aggressive chemicals (hydrocarbons, refrigerants, solvents, etc.)
Mold growth and short circuits
High temperatures and thermal cycling

They also offer high dielectric strength and include UV tracers for easy inspection and repair of coated boards.

Application methods
Conformal coatings are applied in thin layers using various techniques based on viscosity:


Brushing, for touch-ups or small production runs
Spraying, for fast and even coverage
Dipping, for complete board coverage

Complete product offering
Samaro provides multiple conformal coating technologies to meet various performance and environmental needs:


Acrylic coatings: fast drying, good mechanical and chemical resistance
Polyurethane coatings: excellent abrasion and solvent resistance
Silicone coatings: high flexibility and exceptional thermal resistance
Water-based and VOC-free coatings: eco-friendly solutions for sensitive environments

Complementary products such as thinners, PCB cleaners, and peelable masks are also available to support your coating processes.
