Escoat® P-77 Non- Silicone Release Coat


Escoat P-77 is a polyolefin masterbatch of a non-silicone release coating used widely for pressure sensitive labels, film, and tapes applications.  The Escoat P-77 masterbatch is produced using a linear low-density polyethylene (LLDPE) carrier resin.  The masterbatch can then be blended with polyethylene resins and extruded as a film with release coat in it.  The release coat under most conditions will bloom to the surface and act as a release film/layer.  No solvents are then needed to apply the release coating.  The release coat used has a high degree of purity, quality and tight melting point range that offers superior properties and performance to critical release coat users.  The Escoat P-77 can be used on films with adhesives based on natural rubber, SBR, SIS, acrylic, etc. primarily for obtaining release in self wound tapes where tight peel is mandatory.
