Potting compound resins provide a permanent protective solution for electronics that are meant to face challenging environmental influences. These can include mechanical shock, humidity, dust and heat. By filling a complete electronics assembly, potting compounds protects components from damage and ensure the safety of the product.

At ConRo Electronics, we understand manufacturers need reliable potting compounds to protect their components. All of our products meet the highest safety, quality, and performance standards and come from top quality brands such as Henkel Loctite.

Conro Electronics is an authorized distributor for Henkel.

A wide range of potting compound resins is available, to meet the specific needs of every application:

  • Epoxy. Epoxy resins offer outstanding mechanical strength and chemical resistance and provide long-term protection against moisture. Their qualities make them perfect for outdoor applications where durability is required. Their downside is a limited flexibility.
  • Polyacrylate. Often used to protect components from contact with oil and water, polyacrylates are common in the automotive industry.
  • Silicone. Silicone compounds offer the highest flexibility and excellent protection from moisture. They are also highly resistant to heat, making them perfect for high temperature applications (up to 200°C). Their downside as a low mechanical strength.
  • Urethane. Urethane and polyurethane compounds offer a “middle ground” between epoxies and silicones, with a good balance of strength and elasticity. Their working temperatures, however, need to remain below 125°C.

Potting compounds are available in 1-part and 2-part formulations. All potting compounds cure by generating a reaction between the resin and a hardener. In 2-part compounds, the hardener is provided as a separate component, requiring mixing before application.

Using potting compounds provides numerous benefits, including:

  • Improved mechanical strength
  • Resistance to shock and impact
  • Protection from environmental factors (water, dust, etc.)
  • Protection from corrosion
  • Resistance to chemical agents
  • Improved heat dissipation
  • Electrical insulation
