Addition of aluminium oxide (Al2O3) to improve the characteristics of the indicator.
The drying agent starts colour change already at a relative humidity of 10%, which provides a clear and reliable control
of the moisture.
The moisture adsorption rate is indicated by colour change from orange to white (transparent), at full saturation;
a water content of 6% of its own weight.
The function persists for a while after the colour has changed to completely transparent.
