Can you name all of the physical properties of a conformal coating?

Conformal coatings come with multiple physical characteristics that are dependent on the chemistry of the coating.

These properties can be subdivided into three sections, namely liquid properties, process properties, and dry state properties, which can be further subdivided into various individual properties that a conformal coating is composed of.

Liquid Properties

  • Flash point
  • Storage lifetime
  • Appearance and color
  • Density
  • Solids content
  • Viscosity

Process Properties

  • Wetting
  • Capillary
  • Viscosity
  • Wet film thickness
  • Surface tension
  • Pot life
  • Drying and curing

Dry State Properties

  • Edge loss
  • Refractive index
  • Glass transition temperature
  • Coefficient of thermal expansion
  • Flammability
  • Flexibility
  • Abrasion resistance
  • Hydrolysis stability
  • Permeability
  • Chemical compatibility and resistance
  • Corrosion resistance
  • Fungus resistance
  • UV stability
  • Outgassing
  • Thermal stability
  • Thermal shock
