Abstract

The prod. is a synthetic silicate gel with a water content between 90 and 98 wt.% and is used for temporary cooling of surfaces exposed to external air, partic. body parts. The prod. can also be used at the same time as a carrier for e.g. a disinfectant. A typical cooling effect when applied to soft drink bottles 0.33 litres is in accordance with the following table where the bottles were filled with tempered water, 30 g. of clay and silicate gel are spread out over the outside of the bottles. The temp. development in these bottles and an unprocessed control were followed. The ambient temp. was 20.5 deg., and there was a slight wind. 0 minutes - gel 36.7 - clay 36.8 - control 36.7. 5 minutes - gel 30.9 - clay 31.5 - control 35.1. 22 minutes - gel 21.9 - clay 23.2 - control 29.6. 35 minutes - gel 16.7 - clay 21.1 - control 26.7. 50 minutes - gel 14.9 - clay 20.3 - control 24.5. 70 minutes - gel 14.1 - clay 19.8 - control 22.2. 105 minutes - gel 14.5 - clay 20.2 - control 21.
