During the winter months, it is imperative to take all necessary precautions during the transportation of water-based emulsions to prevent freezing. The water based emulsion may be either an organic or silicone based product. All emulsions contain some level of water and will freeze if exposed to a temperature at or below 0°C (32°F). It is recommended to store containers of emulsions at temperatures between 7°C to 35°C (45°F to 95°F).
If a container of the water based emulsion is frozen or thought to be frozen, the recommended procedure is to place the container in a temperature regulated area which will allow the material to be properly thawed to between 16°C to 27°C (60°F to 80°F) without any agitation. Once the material has completely thawed to a liquid state, apply simple baffle mixing until uniform -- usually 5 to 10 minutes of mixing. DO NOT VORTEX OR APPLY HIGH SHEAR TO THE EMULSION WHILE MIXING. After the container of material has been agitated, inspect the surface of the product for the presence of precipitates, solids or surface oiling. Wait approximately 60 minutes and re- inspect the surface of the product. During this time, compare and contrast the visual appearance of the product surface. If the surface of the product has not changed over time then the product is fine to use. As long as the frozen material is properly thawed and thoroughly mixed, there should not be any detrimental effect relative to the performance of the product. If you notice precipitates, solids, surface oiling or a change in color of the product -- do not use. Instead please contact Customer Service at 864-984-7700.
Special Note: The above comment applies to the frozen material itself. As with any water-containing material, damage to the container may result from expansion of the liquid during freezing. Containers should therefore be inspected prior to thawing to ensure that no leakage of liquid has or will occur.
