Canon Kasei CS-37 is a surface treatment agent that is designed to improve the adhesion of coatings and paints to various substrates, including aluminum and its alloys. However, the long-term stability of the treated surface at elevated temperatures will depend on several factors, such as the specific alloy composition, the exposure conditions, and the duration of exposure.
Generally speaking, aluminum alloys are known for their good high-temperature stability, and many can be used at temperatures up to 200°C for extended periods of time without significant degradation. However, some alloys may be more susceptible to thermal degradation or oxidation at elevated temperatures, which can lead to reduced mechanical properties or surface damage.
Therefore, it's difficult to say for sure whether aluminum alloy treated with Canon Kasei CS-37 will remain stable at 200°C for a long time without additional information on the specific alloy and exposure conditions. It's always best to consult with a professional or conduct testing to evaluate the stability of the treated surface under the intended operating conditions.
Canon Kasei CS-37 is a chromate-based chemical conversion coating agent that is commonly used for surface treatment of aluminum alloys to improve their corrosion resistance. While this type of coating can provide good protection against corrosion, its performance at high temperatures can be affected.
The operating temperature of 200 degrees Celsius is relatively high and may cause the chromate coating to break down over time, which can lead to degradation of the aluminum surface and reduced protection against corrosion. In addition, chromate coatings can release toxic hexavalent chromium compounds when exposed to high temperatures or UV radiation, which can pose health and environmental risks.
If you need to use the aluminum alloy at high temperatures for a long time, it may be necessary to consider alternative surface treatments that can provide better thermal stability and corrosion resistance. Some possible options include anodizing, chemical vapor deposition (CVD), or physical vapor deposition (PVD) coatings, depending on the specific application and requirements.
Thanks for your answers. Initially, we plan to use aluminum alloy (2A12) with Canon Kasei CS-37 as the coating agent. Because I'm not sure what will happen to the coating agent at 200℃. Therefore, in the experiment, we chose another coating agent JS-Black. According to its data sheet, it is suitable for aluminum alloy (2A12) operating at 200℃.
