Various conformal coating materials are used to provide protection and improve performance and reliability of PCBs.

This white paper, written by Kazuhisa Ono for Momentive Performance Materials Japan LLC, looks at the advantages of using silicones as a conformal coating on circuit boards, it includes performance comparison data of two new Momentive silicone conformal coating materials against a silicone resin based on the following tests:

  • Gas Permeability
  • Sulphur Resistance Test
  • Gas Corrosion Resistance Test
  • Salt Spray Resistance
