Understand Moisture Damages

Moisture damage is everywhere and it causes inconvenience to our daily life. When humidity is over 60%RH in the air, molding, rusting or even corrosion and oxidation appears to a certain extent on some Moisture Sensitively objects.

What is relative humidity? Relative humidity is the amount of water vapors in the air at certain temperature compare to the maximum amount of water can hold without condensing.

To protect your valuable possessions from moisture damages, relative humidity should be carefully controlled when storing these materials. Without a proper control of relative humidity, moisture damages will not only damage your possessions but also affects your health.

It is strongly recommended to store your Moisture Sensitive materials in proper storage ambient
