Urethane conformal coatings

HumiSeal urethane conformal coatings are high-performance materials that provide excellent resistance to moisture, chemicals, and abrasion for printed circuit boards. They form a durable protective film for demanding environments such as automotive, military/defense, and renewable energy applications.

Key Features

  • Moisture protection: Extremely low moisture permeability provides effective protection again corrosion.
  • Chemical resistance: Highly resistant to fuel vapors, solvents, and corrosive gases.
  • UV fluorescence: The coatings contain a tracer that fluoresces under UV light for quality control and coverage inspection.
  • Safety: The most popular types do not contain free isocyanates.
  • Certifications: Typically comply with MIL-I-46058C, IPC-CC-830, and RoHS standards.
