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:

Conformal coatings can be categorised by many different factors including inorganic

What are the different classifications of conformal coatings?

The family tree of common conformal coatings normally found include organic and inorganic liquid coatings and Parylene.

The evolution of the conformal coating over the last 50 years has led to a large range of conformal coatings with many different variations.

The family tree below shows the common materials normally found including organic and inorganic liquid coatings and Parylene.

The coatings can be further sub divided:

  • Liquid and Vapour Deposition Groups
  • Liquid Conformal Coatings Families
  • Liquid Conformal Coating Resin Types
  • Drying and Curing Subdivision
  • One / Two-Part Coating
  • Solvent / Solvent Free
  • Physical and electrical properties
