Applications involving steam above its rated range or concentrated acids call for a different compound.
Maintenance and OEM teams specify it across medical devices, pharmaceutical manufacturing, and ovens and heated equipment.

As always, verify media compatibility and operating conditions against the requirements of your specific application.
