Superflite's 7800-series urethane reducers thin Superflite varnishes, primers and System 7 topcoats to a sprayable viscosity and control how quickly they dry. Picking the right one for your shop temperature is one of the simplest ways to get a smooth, glossy finish.

SF7860 Cool is fast drying for 60 to 70 degrees F. SF7870 Medium is for 70 to 80 degrees F. SF7885 Warm is slower drying for 75 to 85 degrees F. SF7895 Hot is slow drying for 85 degrees F and above.

Typical use is a half part reducer in System 7 topcoat, up to 50 percent in fabric primer, and 25 to 50 percent in SF80 epoxy primer. All reducers are sold by the gallon.
