Solvex™ Petrolatum

Solvex Petrolatum is a stabilized form of petroleum grease that is particularly suitable as a tack reducing agent for all types of web offset and some low-tack uncoated sheetfed litho paste inks. Unlike solvents and oils, Solvex petrolatum will not reduce viscosity rapidly when reducing tack.


Solvex petrolatum can also be used in limited quantity in heatset inks as a tack stabilizing agent to keep blanket piling due to rapid solvent evaporation under control. For this purpose, no more than 3-5% is recommended as a maximum figure.


Solvex petrolatum is particularly useful as an ingredient in inks that must stay "open" for extended periods of time. However, it is not recommended for use in rapid-setting sheetfed inks. See our products GLO for use in hard-drying litho formulas or Solvex BioGel G for use in web offset formulations.
