Our range of polyurethane conformal coatings provides a robust solution for safeguarding electronic components against environmental factors, offering the following key benefits:

  • Outstanding protection: Polyurethane coatings offer exceptional protection against moisture, chemicals, and dust, shielding electronic components from the harsh effects of the environment.
  • Ease of application: The user-friendly application process ensures a smooth coating, conforming to complex shapes and contours of electronic assemblies. Application methods include dipping, spraying, and brushing.
  • Flexibility and durability: These coatings provide a flexible and durable barrier, accommodating the natural expansion and contraction of electronic components due to temperature variations, ensuring long-lasting performance.
  • Excellent dielectric properties: With superior dielectric properties, polyurethane conformal coatings prevent electrical leakage, enhancing the insulation of delicate electronic components.
  • Fluorescent: Polyurethane conformal coatings can be optically excited under UV-light, fluorescing for straightforward inspection.

It’s essential to acknowledge some considerations in choosing polyurethane coatings:

  • Hard to remove: Due to the coating’s high resistance to solvents, polyurethane coating removal can be challenging, risking damage to electronic parts or compromising visual appeal.
  • Long curing times: Polyurethane coatings might have a longer curing time compared to some other coatings, influencing production timelines. Accelerated curing requires additional equipment.
  • Thicker coatings: Polyurethane coatings may require a thicker layer to achieve the same level of protection as other coatings, potentially impacting the overall size of the electronic assembly.
