SF7870 is Superflite's medium-drying urethane reducer for mild to warm shop temperatures of 70 to 80 degrees F. It can be used with any Superflite varnish, primer or System 7 topcoat, and it is the reducer most shops reach for in typical conditions.

The reducer thins your coating to a sprayable viscosity and controls how quickly it dries. Matching your reducer to shop temperature helps the coating flow and level properly for a smooth, glossy finish.

For other conditions, choose SF7860 Cool (60 to 70 degrees F), SF7885 Warm (75 to 85 degrees F) or SF7895 Hot (85 degrees F and above). Sold by the gallon.
