Momentive's Conformal Coating whitepaper discusses how despite the higher gas
permeability of silicone relative to other polymers, formulation design approaches and improvements in adhesion can allow silicone to mitigate gas permeability concerns, and help deliver corrosion resistance performance that meets emerging expectations for conformal coating materials in electronic applications.
The paper includes performance comparison data of silicone to other conformal coating materials such as acrylic, polyurethane and epoxy based on the following tests:
- Gas Permeability
- Sulfur Resistance Test
- Gas Corrosion Resistance Test
- Salt Spray Resistance
