NEO BLUE

The color is deep blue in drying condition and changes to reddish violet when adsorbing moisture. This color-changing is distinguished at 10~40% relative humidity. After color-changing it keeps on absorbing moisture.

Heating about 3 hours at 130C makes color change from reddish violet to deep blue and restores original indicating and moisture-adsorbing capability.

According to EU Directive 98/98/EC, cobalt chloride applied to the current Silica gel indicating desiccants is classified as a carcinogen. Silica gel NeoBLUE^¢ç applies safe substance as a indicator, which is not classified as toxic according to the current EC legislation.

SiO2 99.7%, organic color indicator 0.07%
