The main application of this type Water Based Flexo Ink in India is mainly in cellulose supports and certain plastics.
mainstays
• corrugated board: kraft, coated, recycled
• paper: glossy, coated, paraffin, cellulose, coated
• polyethylene: sacks and bags
COMPOSITION
• pigments: must be appropriate because the pH of these inks influences them
• resins: acrylic resins are used
• Solvents: -5% paper and 10% to 15% plastic
• additives alkalizing (solubilize resins as amines) and defoamers (antifoaming has the characteristics of having low voltage surface, easy to extend and partial insolubility in the medium)
CONDITIONS REQUIRING AN INK WATER
- Stability stock
(For virgin inks: stock of five months for diluted inks: stock 7 days)
- Extensibility
(Dissolution of 19% to 22 "for work in machine)
- Good rub resistance
- Good transfer of the support cliché
- No foaming machine
(Problems that can be found are: excess paper fibers, not suitable defoamer emulsion or air introduced by the machine itself)
- That are parafinables in certain cases
- quality
- colorful
ADVANTAGES OF Water Based Flexo Ink in India
• reduced pollution, which is a low cost
• reduced danger
PROBLEMS water-based inks
• slower rate of drying
• higher surface tension
• less resistance to heat than nitrocellulose
• less bright than solvent-based nitro, they are duller
• may have trouble foaming
• cleaning of the elements involved in the process must be appropriate and be made immediately.
