Intertherm 2205 Aluminium-pigmented Heat-resistant Coating belongs to heat-resistant coatings, epoxy coating system. Intertherm 2205 is applied directly to steel structure surfaces at temperatures from 60°C (140°F) to 205°C (401°F); during maintenance, equipment can remain in operation, reducing downtime. Intertherm 2205 provides corrosion protection and heat resistance for components under insulation (CUI); when applied directly to hot component surfaces, application is straightforward. When Intertherm 2205 is used at temperatures above 100°C (212°F), only 10 min curing time is required before the insulation can be reinstated. Parameters on this page: DFT 100–200 µm (4–8 mil), theoretical spreading rate 8.50 m²/L.

Steel substrates: Intertherm 2205 is designed with maintenance in mind, so it can be applied to surfaces prepared to different standards, such as hand sanding, power tool cleaning or abrasive blasting, including St2, St3, Sa2, Sa2½ (ISO8501-1) and SP2, SP3, SP11, SP6, SP10 (SSPC).
All surfaces to be painted must be clean, dry and free of contaminants. Before painting, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.
For surfaces prepared by hand or power tool cleaning, areas not sufficiently treated with a needle gun shall be abrasive blasted to ISO8501-1 Sa2/SSPC-SP6. This applies particularly to Grade C or Grade D rust according to this standard.
Stainless steel: Intertherm 2205 can be applied to stainless steel surfaces. The surface shall be clean and free from oil; abrasive blasting or power tool cleaning shall be carried out to achieve a roughness of 35–50 µm.
Aged coatings: Intertherm 2205 is suitable for application over most old coating systems, including residual inorganic zinc silicate coatings. All loose, flaking or poorly adherent coatings shall be removed; bare steel shall be prepared in the same way and shall not have a polished surface. Old epoxy coatings and glossy surfaces shall be abraded; all areas to be coated shall be clean, dry and free from oil and grease.

Intertherm 2205 is a low-VOC, low-surface-preparation, high-film-build coating that provides corrosion protection for pipes, valves and tanks with operating temperatures up to 205°C (401°F) and intermittent temperatures up to 230°C (446°F).
For these hot-service steel structures prepared by hand or power tool cleaning, Intertherm 2205 is the preferred coating product
| and does not affect continuous operation of steel structure equipment during maintenance. | Designed for steel structures exposed to air or under insulation. Brush or roller application achieves the desired performance. |
|---|
As Intertherm 2205 is designed for application to steel structures with operating temperatures above 60°C (140°F), volatiles are released relatively quickly during application; personal protective equipment must be worn.
To achieve the desired corrosion protection, a minimum DFT of not less than 200 µm for the paint in the coating system is essential, and can be achieved by multiple coats (2 coats recommended).
When the coating is applied to structures with surface temperatures above 100°C (212°F), the paint thins rapidly. If sagging occurs, ensure the film is re-applied to form a uniform film before curing. During application, when paint on the brush or roller begins to cure, replace the brush or roller. Thinner is not recommended.
When Intertherm 2205 is used at temperatures above 100°C (212°F), only 10 min curing time is required before the insulation can be reinstated.
Exposure to high-temperature environments may cause the colour of Intertherm 2205 to change from aluminium pink to faded bronze. This is normal during curing and does not affect paint performance.
Intertherm 2205 is an immersion-grade coating suitable for long-term wet and hot environments. However, Intertherm 2205 is not suitable as a tank lining coating. Intertherm 2205 is not suitable for buried environments.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that it also affects the VOC value.
Intertherm 2205 can usually be applied directly to metal surfaces and can be used in coating systems with the following paints: Interbond 2340UPC, Interplus 256, Intertherm 228HS.
