High Temperature Silicone
High temperature silicone products are used where joints run hot, including engines and exhaust-adjacent parts. The manufacturer's published high temperature RTV gasket makers are described below in the manufacturer's own words.
No temperature rating is stated on this page beyond what the manufacturer publishes for a named code. Confirm the peak and continuous temperatures of your application before ordering.
High temperature in this range covers two different product types: silicone sealants and gasket makers for hot joints, and a high temperature paint spray for coated surfaces. They are not interchangeable. A paint spray does not seal a joint, and a gasket maker does not coat a surface. State which job you need in your inquiry.
