Escoat® P-20 Liquid Release Coat

Introduction:

Escoat P-20 Dispersion is a water-based non-silicone product especially produced for use in pressure sensitive labels, film and tapes applications where a non-solvent is needed.  The high degree of purity, quality and tight melting point range of the Escoat P-20 offers superior properties and performance to critical users.  Escoat P-20 Dispersion can be used on OPP or PET films with adhesives based on natural rubber, SBR, SIS, acrylic, etc. primarily for obtaining release in self wound tapes where tight peel is mandatory.  Escoat P-20 Dispersion is expected to give a peel strength 2-3 times the level expected from most silicone release agents.
