Ketonic resins are hard resins made by condensing cyclohexanone with an aldehyde. Small additions improve many solvent-based inks and lacquers.
What they add
- Gloss and hardness of the dried film
- Better pigment wetting, so higher colour strength from the same pigment
- Improved adhesion to many substrates
- Faster solvent release and drying
Compatibility
Ketonic resins are compatible with nitrocellulose, many polyamides, alkyds and other film formers, and dissolve in common ink solvents such as alcohols, esters and ketones. Check compatibility and blocking in your own system.
Typical uses
Flexo and gravure inks, screen inks, nitrocellulose lacquers and ball-point pen inks.
