3M non-silicone secondary release liner 4935 is a 3 mil clear polyester film with a non-silicone release coating applied to one side, suitable for applications where silicone release agents can leave residue or interfere with subsequent processes. The 4935 release coating delivers a medium release level. PET film liner construction adds strength for reduced tear-outs and easy converting. For specialty applications where silicone agents can slow down productivity or lessen finished product quality, 3M non-silicone secondary release liner 4935 is an excellent choice. Instead of silicone release chemistry, this 3 mil polyester film liner features a non-silicone, fluoropolymer release coating that delivers a medium release level. This coating is applied to 1-side of the film to suit secondary and double-liner constructions. High strength polyester film can help reduce breakage during automated cutting and dispensing processes. 3M non-silicone secondary release liner 4935 provides a moderate release level. 3M non-silicone secondary release liner 5053 offers a lower release level, and 3M non-silicone secondary release liner 5932 offers the tightest release level. Recommended applications - applications where silicone can leave residue or hamper subsequent processing, automated die-cutting and dispensing where tear-outs are a concern, applications requiring medium release level. 3M secondary liners are available in a variety of designs and materials. 3M provides secondary release liners in polycoated and densified kraft, flatstock, HDPE and clear polyester film for a full range of adhesives and converting processes. 3M since 1925 when a lab assistant invented masking tape, 3M has been applying science to life developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. And all of it goes into each industrial labeling and adhesive products like 3M non-silicone secondary release liner 4935, to help businesses operate faster, better and more efficiently.
