Automotive parts created by casting with release liners.

Casting and Release Liners

Release liners (Silicone or Non-Silicone) are typically used as a film intermediate in the manufacture of complex composite constructions where there is a need to protect an adhesive layer. The various release coating options offered are compatible with numerous adhesive systems and can be directly coated or used as a cover layer. Release liners manufactured with our unique technology are manufactured in an ISO 9001:2015- QMS certified facility with clean room offerings.
