Storage:
HIFLON 603 Dispersion can be stored at 10 – 20 oC for months together. Generally, recommended storage period is 6 – 8 months. However, to avoid the possibility of slight sedimentation, it is advised to shake the dispersion gently once in a week. HIFLON 603 Dispersion should be prevented from getting high rise in temperature which can result in irreversible partial or total coagulation. For extra safety, avoid storing at a temperature of equal to or less than 5 oC for short time. One should avoid subjecting HIFLON 603 dispersion to vigorous agitation, shock or vibrations. Strictly avoid contact with solvents miscible with water such as acetone, methanol etc.
