Ever wondered what a conformal coating is actually made of?

Conformal coating is a kind specialized paint or varnish that is made of volatile and non-volatile components.

A Background on Paint and Varnish

The ISO 4618: 2014 defines paint and varnish as a liquid, paste-like or powder product which, when applied to a circuit board or other substrate, results in a coating.

Hence, conformal coating is a specialized material that belongs to the paint and varnish family

Composition of Conformal Coating

A conformal coating is comprised of two main elements namely the volatile and non-volatile components.

1. Volatile elements – composed of solvents, water, and additives

2. Non-volatile elements – composed of binder and colourants

It’s important to note that every conformal coating has a unique set of physical and electronic properties.

This allows for flexibility when choosing the most appropriate conformal coating.
