Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving ketones and esters or hot water and steam call for a different compound.
Maintenance and OEM teams specify it across oil and gas, high-temperature process equipment, and semiconductor equipment.
