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. Control the moisture, prevent condensation, protect the cargo.

The use of the biocide (DMF) dimethylfumarate – which has caused severe allergic reactions in hundreds of consumers, because of its use in every day consumer products such as couches and shoes – looks set to be banned across the EU. Today, Member States voted in favour of a draft European Commission Decision to ensure that consumer products, such as leather furniture or footwear, containing the strongly sensitising (DMF) are not placed on the market in the EU. If already on the market, these products will have to be recalled and withdrawn without delay. In countries such as France, Finland, Poland, Sweden and the UK, consumers exposed to products containing DMF, have experienced serious health problems including skin itching, irritation, redness, burns and, in some cases, acute respiratory difficult. The draft Commission decision is for an emergency EU wide measure, pending the adoption of a more permanent regulatory solution. Following today’s vote, the draft Commission decision will be submitted for consultation to the European Parliament before going before the College of Commissioners for final approval. EU Consumer Affairs Commissioner Meglena Kuneva, said: “There can be no compromise on safety. I am pleased to see that that the RAPEX system has been functioning well to ensure dangerous goods containing DMF are quickly removed from the market. But we need to go further with urgent EU action to tackle the problem at source. An EU wide ban on the use of DMF in all consumer goods is designed to eliminate the serious health risks and in particular the severe allergic reactions suffered by some consumers when they are exposed to this chemical simply by using everyday leather goods.”

Yes, such a difference could be all the difference between no damage and disaster. The moisture behavior of most agricultural products have a strong exponential character.

Watchmen products contain calcium chloride that aggressively capture and absorb moisture from the air. They dry the air. When the air is dry, this prevents moisture problems.

A desiccant is a hygroscopic substance that induces or sustains a state of dryness (desiccation) in its local vicinity in a moderately well-sealed container.

Moisture processes have an exponential character. This means that even a small change in circumstances can have a huge effect on the outcome of the shipment. Absorbents create circumstances that allow almost all of the moisture to remain in the cargo even while the level of humidity in the air is lowered by a crucial amount, sufficient to prevent damage. It is a question of ”leverage”. This is by absorbing moisture from the air and reducing the relative humidity.

No, we have not changed our product’s ability to absorb moisture. Check your container and your packaging material. Did you just start to store your pallets outdoors? Have your shipment routines changed? Does your forklift drive into the container with snow on the wheels? Did you just change supplier of crates? You cannot tell by looking whether wood or cartons are dry. The moisture properties of wood and cartons have an exponential character. It makes a huge difference if your pallets have a moisture content of 20% instead of for example 15%.

Much damage to cargo is caused by prolonged periods of elevated humidity such as container rain, container sweator (a super saturation event). It is common that cargoes loaded at a cool temperature and then moved into warm conditions suffer damage in the center of the cargo. This is a result of a difference in temperature between the outside and the center of the cargo. Warm air from the outside of the cargo becomes humid as it moves into the cooler center. Watchmen Poles and other Watchmen products protect against this effect even though the desiccant are mounted on the container walls.

Your cargo or the packaging, including container floors, pallets and crates contain moisture that can evaporate into the air during transport. Wet packaging material is the most common cause of unexpected moisture problems.

No it is not. Calcium chloride is non-toxic and environmentally safe. The brine is somewhat similar to salty seawater and may cause slight irritation as it dries yourskin. We recommend that you wear gloves when handling used poles. If you would get splashed by brine just rinse it off immediately with plenty of fresh water. No it is not. Calcium chloride is non-toxic and environmentally safe. The brine is somewhat similar to very salty seawater, and may cause irritation and rashes if left to dry on the skin. We recommend that you wear gloves and goggles when handling used poles. But should you get splashed by brine just wash off immediately with plenty of fresh water.

Yes, Watchmen products will help. You can forget about your tectyl, coatings, oil-paper and plastic wraps that are expensive both to apply and remove. Your container can probably be equipped with a sufficient number of Watchmen products to protect against any damage at less cost than your present packaging.

Yes, as long as there is some access of air through the top and bottom of the pallets. If this is not possible, a spiked roller may be used to tear holes in the shrink wrap.

Moisture diffuses very effectively, even through a seemingly compact cargo. Experience shows that our products will make a difference even to mould growth inside cartons. It is, however, necessary that some free space is left in front of each absorbent, if they hang from the container wall.

Many containers are lined with kraft paper primarily for reasons of hygiene or to simply isolate the cargo from direct contact with the container walls. The liner will act as a kind of sponge, catching and absorbing any droplets of water and then re-evaporating the moisture into the air. If a liner is used without absorbent it could contribute to a kind of pumping effect, drawing moisture out of the cargo and then releasing back into the air. When used together with Watchmen Poles or another Watchmen product the liner will act as a buffer in extreme conditions, this will prevent any container rain from reaching the cargo. Much the same can be said for so called dew cloths.

Calcium chloride absorbs moisture even when the humidity is not very high. This protects the cargo against damage caused by prolonged periods of elevated humidity. Some kinds of steel start to corrode at 70% relative humidity, moulds can grow at 80% relative humidity and at near 90% relative humidity lots of things can go wrong. Yet, our products based on calcium chloride are also at their most efficient protecting against condensation. Most other products, such as silica gels, are only effective in very humid conditions and for a short time period before they become over-saturated.

Consumer goods are often shipped with a lot of cardboard packaging. Even if the boxes seem dry they could literally hold hundreds of liters of water.
