Verrillon’s® traditional fiber coating offering includes materials rated to 150°C (MTDA), 200°C (SPFA) and 300°C (Polyimide). For environments where temperatures are between 150°C and 200°C, Verrillon has introduced its new Carbon/Silicone/Mid-Temp Acrylate coating (CSMTA), designed to address such mid-temperature range applications. This coating combination has been fully qualified for use at 175°C in both long-term exposure and extensive cycling between -40°C and +175°C. In addition to its excellent temperature handling, the 175°C coating exhibits exceptional strippability with traditional mechanical tools due to the unique properties of its primary coating.
