What are the important physical properties of a conformal coating in production?

Conformal coating is composed of different physical properties. One of which is liquid. The liquid properties need to be defined prior to the conformal coating.

The properties include flash point, storage lifetime, appearance and colour, density, solids content, and viscosity.

Liquid properties overview:

  • Flash point: the temperature needed for an organic compound (solvent) to release enough vapour in the air
  • Storage lifetime: shelf life of the conformal coating
  • Appearance and colour: mostly clear
  • Density: measured by a pycnometer
  • Solids content: non-volatile material that remains after the coating is done
  • Viscocity: showing the internal friction in a fluid resisting flow
