4.b. Minimum storage temperature: 27ºF
4.c. Optimum storage temperature range: 32-140ºF
4.d. Temperatures of phase separations and chemical changes: SPLIT DECISION SC is stable and phase separation will not occur at temperatures within the above storage range. Repetitive freeze/thaw cycles may cause stratification. This stratification is readily dispersed by minimal mixing.

V. SHELF LIFE
The recommended shelf life is one year.

VI. RECOMMENDED APPLICATION PROCEDURE
1. Application Method:
Spray on oily surface. SPLIT DECISION SC forms a loose emulsion with oil that separates within seconds. Oil displaced from surface can be skimmed from the rinse water or absorbed with an oil absorbent.
