VANCRYL® 65

VANCRYL 65 is a medium molecular weight solid acrylic resin that is soluble in alkaline water solutions. It provides excellent properties for high-solids gravure inks and waterborne clear overprint varnishes. Here's a summary of its technical datasheet:

Introduction:

• VANCRYL 65 is a solid acrylic resin soluble in alkaline water solutions.
• It facilitates the preparation of low VOC inks and coatings as it does not require co-solvents like isopropanol.
• Suitable for high-solids gravure inks and waterborne clear overprint varnishes, providing high gloss and rapid drying.
• Coatings made with VANCRYL 65 exhibit high gloss, scuff resistance, hardness, and excellent resolubility.
• Compatible with most acrylic and maleic resins.
• Also effective as a protective colloid in the production of styrene acrylic copolymer emulsions.

Key Performance Properties:

• Low solution viscosity at higher solids.
• Low VOC formulas possible.
• Excellent transfer and holdout on porous substrates.
• High gloss.
• Low foaming.
• Excellent compatibility.
