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
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.
