JONCRYL 631
JONCRYL 631
JONCRYL® 631 is a hard non-film forming, controlled particle size, RC acrylic emulsion designed to hide the brown background of natural kraft substrates. This emulsion, when used as a letdown vehicle, results in more intense, brighter printed colors. The semi-opaque nature of JONCRYL 631 allows for the reduction of pigment levels as well as inorganic extenders.
This product is recommended for applications such as:
- Printing inks for flexographic or gravure applications
Features & Benefits
- Improves ink brightness and color intensity
