Frequently Asked Questions

1. How does TOPDRY Desiccants help solve moisture problems?
This unique product absorbs moisture by extracting water vapor present in the air, thus preventing the humidity inside the container from reaching dew point and condensing. The desiccant then starts to turn into a gel as it continues to absorb moisture. The water absorbed is retained due to the presence of a special binding agent, thus preventing it from leaking.

2. What is Relative Humidity (RH)?
Relative humidity measures the amount of moisture in the air. It is expressed in a percentage of how much moisture the air could possibly hold. The wetter or damper the air is, the higher the relative humidity. The drier the air feels, the lower the relative humidity. Thus, 100% humidity is actually rain.

3. What are the most common problems caused by moisture?
Moisture in containers cause problems such as mold, fungus, mildew, rust decay, lumping, caking, agglomeration and decomposition. Moisture can also cause electronics to malfunction.

4. Is moisture damage always instantly visible when handling the cargo?
Unfortunately not. Though common forms of moisture problems such as corrosion, mold or fungus are visible on the cartons, surfaces etc there are some kinds of damage that is not visible. Mostly these damages are internal and visible only when the customer opens the shipments. In the case of devices, they often cease to function the way they should.

5. I fumigate my containers; do I still need to put in desiccants?
Fumigation and using desiccants have two different purposes and are not alternatives to protect your goods against moisture damage. Fumigation is primarily to eliminate insects and eggs in the container and in the goods. It has no influence on the humidity inside a container. Desiccants will not influence the effects of fumigation and can easily be put in before or after fumigation. For more information on fumigation, please read our article on this matter.

6. If I use TOPDRY, will I have any more moisture problems?
TOPDRY Prevents Moisture damage by controlling the Relative humidity and indeed prevents those problems. However, the ventilation holes in the container need to be closed and the number of units to be put in a container needs to be adjusted to the situation.
