Helping Engineers Select the Right Potting Compound

Fabrico helps engineers working in electronics and electrical equipment to select the potting compound that will work best for their application.

Potting enables an engineer to secure a component, protect it from natural elements such as moisture, and electrically insulate it so that it can perform as designed. There are many considerations in evaluating a potting material:

• The kind of device/component to be potted
• Part characteristics, including voltage
• The operating environment
• Acceptable curing/gel time
• Adhesive characteristics
• Coefficient of thermal expansion of the potting compound and the device
• Application method (manual or automatic)
• Overall cost

Fabrico can help engineers to select from a wide range of potting compounds available through its extensive supplier network, including:

• Epoxy
• Hot melt
• Unsaturated polyester resin
• Urethanes
• Silicones
• UV curing materials

As a materials specialist, Fabrico can recommend new potting compounds specifically made for today’s more complex and denser electronic and electric assemblies. Working with the engineering team, Fabrico investigates the appropriate potting compound that will work with the substrate, end-use, and manufacturing process. With its in-house test lab, Fabrico can look at alternative compounds based on the customer’s specifications.
