ESTISURF® A7

ESTISURF® A7 is a non-ionic or anionic emulsifier package for the production of semi-stable emulsions. It contains corrosion inhibitors for iron and yellow metals. It shows good blending properties with hydrocarbon solvents. This has been successfully tested by the FOGRA Institute as a 3% solution in 97% D60 solvent.

Industrial Application
  • ESTISURF A7 is developed for application in blanket and roller washes for the offset printing industry based on de-aromatised hydrocarbons.
  • Cleaners made according to the guideline formulation form semi-stable emulsions that will separate over time. The emulsions have a low viscosity in all mixing ratios with water.

  • A cleaner based on de-aromatised hydrocarbon and ESTISURF A7 has the following features:
  1. The emulsion has a low viscosity in all mixing ratios with water
  2. It does not swell the rubber materials used in the off-set printing process
  3. There is no attack on the CTP plates
  4. It is easy to flush with water
  5. It provides excellent corrosion protection for ferrous and yellow metals
  • The solvent properties can be improved by addition of 1-10% of ESTISOL 242 or ESTISOL 312. This is especially recommended when working with higher boiling hydrocarbons such as D80, D100 and D120.
