JONCRYL 646
JONCRYL 646
JONCRYL® 646 is a high molecular weight, colloidal emulsion designed to minimize the cost of inks for corrugated board. The balance between the molecular weight and the composition of this emulsion results in the ability to maintain viscosity of corrugated inks with a minimal amount of polymer.
This product performs as a very efficient letdown vehicle by allowing the formulator to maximize the percentage of water in the ink, while maintaining viscosity and printing properties.
JONCRYL 646 is recommended for applications such as:
- Printing inks for flexographic or gravure applications
Features & Benefits
- Cost-effective letdown vehicle
- Effective thickening agent
