NuSil^® potting and encapsulating silicone materials from Avantor^® provide excellent protection against shock, vibration and outside contaminants. Manufacturing leaders in diverse industries, including healthcare, space and optoelectronics, rely on our silicones for their power electronics, displays, sensors, and other general electronics assemblies.

Our industry-leading selection of materials range from low modulus gels to low viscosity elastomers and lightweight foams. Silicones offer several material characteristics that make them well-suited to potting and encapsulating applications:

• Gels: Commonly used for coating sensors, gels are two-part low viscosity, platinum-catalyzed systems that will cure at room temperature or with heat. NuSil gels can be customized to accommodate pot life, cure rate and viscosity requirements.
• Elastomers: Flowable in their uncured state and tougher than gels, our portfolio of elastomers offer a wide range of options, including optically clear properties and low and high temperature cure.
• Foams: Our gels offer lightweight and highly compressible flexibility in a low viscosity silicone.
