Composites liners

Elkem's SILCOLEASE products provide release coatings to improve the processing of sophisticated composite material parts in a wide range of industries.

Composites enable the production of parts that are higher in strength and lighter in weight, and new raw materials are continuing to drive innovation. For example, wind turbine blades can be bigger, more efficient and provide more energy, airliners can weigh less and be more fuel efficient, and tennis racquets can swing faster and absorb more impact.  

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.  

Key factors for efficient silicone release systems for composites

Removing a silicone-coated release liner
Removing a silicone-coated release liner
  • 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.
