Escoat WPX Release Coat is a non-silicone, carbohydrate polymer emulsion which provides a moderate release performance that is writeable and inkjet printable.   Escoat WPX coatings give a consistent release performance for various tape and label products, specifically bond paper, postal readdress labels, “Post-It” type packs for give away, coupons, prescription pads, and such.  The unique balance of release performance and inkjet receptivity is unmatched in release coat technology.  Variations of Escoat WPX are available for lower peel performance in the new “super sticky” type label pads.

Mixing Instructions: 

Depending on the type of substrate and pressure sensitive adhesive, the concentration of solid matter required should be determined by laboratory trial. Escoat WPX Release Coat diluted to between 12.0%
to 25.0% solids will be adequate in most pressure sensitive applications. Some applications may require a higher solids concentration. Stir well before use.


Escoat WPX Release Coat is diluted in water to achieve application concentrations. Depending on the substrate and adhesive, the solids concentration should be determined by lab test. Recommended levels are between 12.0 – 25.0%. Some applications may require a higher solids concentration. Escoat WPX coatings are designed for use on paper substrates only. Anchorage to any film substrates should be thoroughly tested before use. The coated substrate must be thoroughly dry before rewinding.


  • Offers a low ATB and unwind value. The smooth release properties are similar to silicone release coatings and are valuable when used against the ‘microsphere’ acrylic adhesives typically used on low peel label applications.
  • Writeable and Inkjet printable.
  • Silicone free to avoid silicone contamination, or poisoning of the adhesives.
