Silicone coatings facilitate composites manufacturing

Elkem Silicones Silcolease products provide release coatings to improve the processing of sophisticated composite material parts in a wide range of industries

The growing use of composites in our lives offers manufacturers the capability to produce parts that are higher in strength and lighter in weight. The composites industry continues to expand in new and different raw materials and drive innovation for reducing weights, decreasing costs and improving fuel efficiencies.  Wind turbine blades, for example, can be bigger, more efficient and provide more energy, airliners can weigh less and be more fuel efficient, tennis racquets can swing faster and absorb more impact.  The use of composites continues to find new applications in our world in the most diverse applications.   

Elkem offers a broad range of Silcolease silicone release coatings to support the fabrication of composite materials used in transportation, aerospace, energy, construction, electrical and electronic, medical, marine and consumer goods markets. These coating systems are designed to provide stable and consistent release during the formation of prepreg and carbon fiber materials with specific formulations to enhance the release of polyurethane, epoxy, bismaleimide, or phenolic systems.  

What are the key factors for efficient silicone release systems for use in the composites industry?

  • Reliable and consistent release force
  • Low coefficient of friction to reduce rub or drag during removal
  • Low extractable silicone formulations to minimize cross contamination or silicone migration
  • Excellent adhesion and anchorage to super-calendared kraft or glassine papers and films
  • High temperature resistance
  • High/low release differentials for two-sided applications
