Fomblin® DA305 is the optimum product for use with greases. Solutions of Fomblin® PFPE lubricants formulated with 5% (wt.) of DA305 are clear and stable in storage for over 1 year. These blends can be used in exactly the same manner as non-additivated Fomblin® lubricants for the production of greases. The physical properties of greases additivated with DA305 remain practically unchanged compared to those of the non-additivated greases; volatility may increase slightly, depending on the base fluid, and oil separation may decrease.
Depending on the base fluid, these greases can be used at temperatures ranging from -70 to 250 °C.
