Decrease aircraft downtime with fluorosilicones

Fuel and common solvents on aircraft can degrade materials, leading to additional maintenance, unplanned downtime or catastrophic failure. This unique challenge leads aviation and defense manufacturers to often choose fluorosilicones for their engineered resistance to degradation from exposure to hydrocarbons and temperature extremes.

NuSil sets the standard for fluorosilicone performance and purity

  • Formulated to maintain dimensional shape when exposed to hydrocarbons for superior stability compared to other materials
  • Broad portfolio of custom and standard solutions, including adhesives, sealants, coatings, sheeting, molding materials, gels and foams
  • Strong regulatory support and proven history:  AS9100 and ISO 9001 certified; compliant with applicable requirements; and expertise built on a flight heritage of more than 40 years.

Considerations When Selecting a Fluorosilicone

There are many options when using a fluorosilicone as there are many forms and cure chemistries available. This versatility makes fluorosilicones ideal for diverse applications such as O-rings, gaskets, seals, molded parts, coatings, gap fillers, adhesives, sealants, potting and encapsulation. Alongside standard products, NuSil silicones have the ability to be customized for specific requirements.

Understanding the needs and constraints of an application can help clarify which fluorosilicone option is best. Here are some considerations when selecting the right fluorosilicone for your application:
