KD's Silica gel
NeoBLUE® has a characteristic
of applying environmentally, biologically safe organicachemicals
excluding heavy metals differently from other current
indicating desiccants containing cobalt chloride.
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.
