Product Features and Benefits
• low viscosity
• Low surface tension
• Gives good spread and wetting
• High flash point (> 100°C/> 212°F)
• soluble in water

  application
• Improves wetting on difficult-to-coat substrates with waterborne coatings.
• Improves the wettability of water-soluble flexographic and gravure inks on high gloss packaging materials such as polyethylene, polypropylene and polyethylene paraxylate.
• Reduce the amount of organic co-solvents used to improve wettability and improve print quality.

  Typical physical properties

(The following values are not available for specification)

  Application method  
       In ink formulations, DOWSIL™ 67 Additive is typically added in the range of 0.1 %–1.0 wt %.
The surface fluidity of DOWSIL 67 Additive can be expressed by comparing the equilibrium and kinetic surface tensions of aqueous solutions (as shown in Table 1).
