WCHEM WATER DISPERSIBLE ACRYLIC RESINS
WChem are water dispersible acrylic resins in solid powder form.
Developed by Pioneer in close cooperation with producers of printing inks, WChem are a series of glycol ether free and APEO free resins for use in water based inks, overprint varnish and graphic arts. WChem resins are suitable for flexographic and gravure printing ink applications.
Pioneer Chemicals’ strong commitment to research & development has been a key element in assuring a continuous flow of new polymers for VOC compliant coatings and inks. Water based inks and coatings formulated with WChem are a good sustainable, consistant quality alternative to solvent based products.
