Grafo-Therm

Grafo-Therm is a textured, water-based anti-condensation coating designed to reduce condensation dripping from shipping container ceilings and help protect stored goods from moisture damage.

Its unique porous structure absorbs moisture and releases it gradually through cyclic drying, helping to prevent water droplets from forming. Applied at just 1.5mm thick, Grafo-Therm provides an effective way to manage condensation inside shipping containers without significantly reducing internal space.

What is Grafo-Therm?

Grafo-Therm is a textured coating containing millions of micropores that absorb and store moisture when condensation occurs. 

As conditions change, the moisture is released gradually through a process known as cyclic drying, helping to reduce condensation build-up and dripping inside the container. The coating’s porous texture increases the effective drying surface by at least 10 times, supporting efficient moisture release. It can absorb up to 1 litre of moisture per square metre and incorporates a fungicide to help prevent mould and fungal growth.

Benefits of Using Grafo-Therm

• Condensation Control: The coating absorbs moisture into its millions of micropores, helping to reduce condensation dripping from the container ceiling. By limiting the formation of water droplets, it helps protect stored goods from moisture damage.
• Thermal Insulation: Grafo-Therm has insulating properties that help moderate temperature fluctuations inside the container. It can help reduce heat transfer, supporting a more stable internal environment for stored goods.
• Mould and Fungal Protection: An integrated fungicide helps prevent mould and fungal growth, supporting a cleaner internal storage environment.
• Corrosion Protection: By helping to control condensation and moisture build-up, Grafo-Therm can reduce the risk of moisture-related corrosion on internal metal surfaces.
• Thin, Space-Saving Application: At just 1.5mm thick, the coating provides condensation control with minimal impact on the container’s internal space.
• Odour-Free Once Dry: Grafo-Therm is completely odour free once fully dry, making it a practical option for a range of storage applications.
• Long-Lasting and Low Maintenance: The durable coating is designed to provide long-lasting performance with little maintenance, helping to reduce ongoing upkeep.

Grafo-Therm can also be applied before a container is fitted with ply lining, providing an additional option for managing condensation in lined containers.

Important Considerations

Grafo-Therm must be thoroughly dry before exposure to frost or condensation. Adequate ventilation is essential to allow the coating to dry properly and release absorbed moisture effectively.

A standard Grafo-Therm treatment is applied to the container ceiling only. Treatment of the internal walls can be requested for an additional charge.
