Silicone release liners

Silicone coated release liners are essential to protect or process all of your sticky materials

What is a release liner?

Elkem offers a range of silicones designed to be applied on one or both sides of a paper or film substrate. Also known as silicone coated release liners, they are used to protect sticky surfaces and to ease their handling. Release liners are used in a wide array of markets and applications where it is critical to achieve a perfect coating to protect and deliver materials such as pressure sensitive adhesives (PSA) used in tapes and labels to their end destination.   Beyond protection of self-adhesive or sticky materials they are also fantastic process aids and are used to enable casting and composite production processes and offer non-stick hygienic solutions for cooking and baking.

Trust our Silcolease™ experts to bring you the support needed to minimize your coating weights, control release forces at all conversion speeds and optimize curing performance. Our silicones product line for release liners is available in the multiple formats to suit your coating systems and requirements: solventless thermal, solventless UV (both cationic and free-radical), solvent-borne and emulsion systems.

Elkem is constantly striving to develop more sustainable solutions so make silicones a key aid for your environmental initiatives!  Silicones help to reduce greenhouse gas emissions by improving energy efficiency and extending the lifespan of your product. Depending on your application you may also be able to recycle or reuse your silicone release liner.

Silicone release liners are ideal for easy release of self-adhesive materials and can be found in many applications: 

  • Self-adhesive labels for packaging decoration or variable information (bar code/QR code)
  • Graphic art laminates for marketing, signing or interior design
  • Self-adhesive bandages and medical devices such as ECG pads
  • Functional food and cooking papers for non-stick performance and grease, water & vapour control
  • Protective films for self-adhesive industrial roofing 
  • Process and casting papers for “pre-preg” composite production and artificial leather
  • Casting papers for artificial leather
  • Tapes for the construction, automotive, and electronics industry 
  • Self-adhesive labels as kid’s stickers, warning or promotional labels 
  • Adhesive protectors for hygiene applications (baby diapers, feminine hygiene etc.)
