Conformal Coatings

What is a Conformal Coating?

A conformal coating is a thin protective polymer layer that is typically applied on top of printed circuit boards (PCBs) and/or other electronic components to protect against particles, moisture, gases, and other potentially contaminating or corroding material.

Silicone Conformal Coatings Solutions

Momentive’s ECC3011 and ECC3051S silicone conformal coating materials employ a distinct formulation that helps prevent the occurrence of corrosion on vital PCB components and surfaces. 

These coating materials have been shown to dispel the commonly held perception that silicones, due to their higher gas permeability, are at a disadvantage in corrosion prevention. In corrosion tests performed by Momentive in accordance with IEC standards, Momentive’s new silicone formulations out-performed a select group of conformal coating materials,  including acrylics, polyurethane, polyolefin and competitor silicone formulations. 

Key Features and Typical Benefits:

• Fast tack-free time
• Solvent-free formulation (100% solid content)
• UV indicator for ease of inspection under black light
• Continuous operating temperature range of -40 ~ 150 °C

Applicable Standards

• Flame Retardant: UL94V-0 certified (File No. E135148)
• Salt spray performance tested in accordance with IEC60068-2-52 Severity 5
