Coatings & dispersions
Silicone coatings and dispersions for protection in power electronics and biocompatibility in medical devices
NuSil® coatings and dispersions from Avantor® create and protect critical parts or technologies for a wide range of applications in the healthcare, space, aviation, defense, optoelectronics and electronics industries.
NuSil silicone coatings and dispersions are elastomers dispersed in a solvent for ease of application. They can be applied in very thin layers to evenly coat a device or surface or used to create a film or thin-walled part with strong elastomeric properties.
NuSil’s broad range of silicone coatings and dispersions offer numerous options to accommodate processing requirements and functional properties:
- One-part or two-part coatings: Our coatings are available as a one-part formulation with no mixing required or two-part configuration offering a longer work time.
- Solvent-based or solventless coatings: Solvent-based coatings are ideal for processes where the silicone is applied as a thin film coating. Solvent-less coatings are non-flammable and do not require controlled environments for handling.
- Special features: NuSil coating options include hydrocarbon-resistance, lubrication, low coefficient of friction and high clarity formulations.

For long term implanted devices (>29 days) NuSil silicone coatings and dispersions are ideal for dipping and spraying processes that produce thin elastomeric films or forms.
Our portfolio of medical-grade coatings and dispersions offer solutions for devices implanted in the body for < 29 days, such as balloons or external devices like needles.
Our space-grade coatings protect against atomic oxygen (AO) while providing resistance to radiation and are used on a variety of spacecraft surfaces and small electronic components.
NuSil coatings feature fuel and heat-resistant properties that protect critical technology in missiles, rockets, launch equipment and unmanned aerial vehicles.
From extending the operating life of circuit boards to providing stability for elastomers, our conformal coatings protect sensitive elements from moisture, contaminants, shock and temperature extremes.
