How are conformal coating materials classified?

I am asked quite often about conformal coating classification. The reality is conformal coatings can be classified in many ways.

However, the IPC do a great job of splitting out the various subdivisions.

They include:

  • Liquid or vapour deposition materials
  • Organic or inorganic coatings
  • The resin types (AR, UR, SR, XY, FC)
  • Drying and curing mechanisms
  • One or two part materials
  • Solvent or non-solvent based

A typical family tree for conformal coatings is shown below:
