How to Protect Waterborne Coatings from Freezing in Transit
Key facts
| Risk | Protection |
|---|---|
| Cold sea routes and winter ports | Temperature-controlled container set to heating |
| Unheated warehouses in transit | Direct routing, short dwell times |
| Overland transport in winter | Heated trucks or insulated packing |
| Unknown exposure on arrival | Check each drum before use |
Why freezing matters
A waterborne coating is a dispersion of resin particles in water. When the water freezes, ice crystals force the particles together, and after thawing they may stay clumped. The coating can look usable but form a weak or patchy film.
Planning the route
Most routes from South China to tropical markets never approach freezing. Risk arises on winter routes through cold ports, overland legs, and storage in unheated warehouses. Temperature-controlled containers can be set to keep the load above freezing.
Checking on arrival
Stir a sample and look for lumps, grit, separation that does not remix, or unusual thickness. If the coating looks wrong, do not apply it; send photos and the batch number.
What this means for your project
Tell us the destination and the expected shipping month. PG-S1 must be protected from freezing; ask for the storage and transport limits of the system you order.
