Mayzo’s water based release coatings represent a “greener” alternative to traditional solvent-based products. Use of water-based release coatings can help to reduce VOC emissions as well as reduce concerns of worker safety associated with the use HAP solvents.
Benefits of water-based release coating include:
- Based on acrylate, polyvinyl acetate / acrylate, fluoro-acrylate, fluoro-phosphate ester, modified polyurethane, polyester / acrylic and modified starch chemistries
- Recyclable and repulpable
- Wide release levels
- Release effects remain stable after oven aging
- FDA approved for indirect food contact (see product list)
- Printable (see product list)
- Uses include masking tape, paper, and “Sticky Note” type applications
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.

Introduction:
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.
