Solvent-based Release Coatings

Solvent-based Release Coatings

Non–Silicone Release Coatings Benefits:

  • High purity provides clean release without ghosting
  • 100% dry powder
  • Based on polyvinyl octadecyl carbamate (PVODC) and polyvinyl stearyl
    carbamate (PVSC) chemistries
  • One step dilution process
  • Dilutable with aromatic and aliphatic hydrocarbons, chlorinated solvents
    and esters
  • Narrow melting point range assures consistent properties
  • Release effects remain stable after oven aging
  • Very low levels of solids needed, thus cost efficient
  • Does not require high temperature processing
  • Pre-dissolved solids for reduced time at use point, less waste
    and mixing accuracy
  • A special heptane blend is available for use in non-HAP applications
  • Liquid versions especially suited for “Siat”, or similar, printing presses

Escoat® P-20 Liquid

Introduction:

Escoat P-20 Liquid is a non-silicone product especially produced and widely used for pressure sensitive labels, film and tapes.  Its high degree of purity and quality offers superior  properties and performance to critical users.  Escoat P-20 Liquid is 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.  Escoat P-20 Liquid is expected to give a peel strength 2-3 times the level expected from most silicone release agents.  In addition, the non-stick properties of the resin in the Escoat P-20 Liquid finds use in a wide range of applications outside the pressure sensitive area.
