At repairing an engine, need in dismantling its exhaust manifold can arise. Disassembly into components often causes difficulties because of sticking of the studs, the exhaust manifold fastening elements.
Hindered dismantling gets a consequence of parts operating at higher loads and temperatures as exhaust manifold is operated in contact with hot exhaust gases. Such operating conditions lead to forming chemical bonds between metals making the connections hard to dismount as there is risk that a part might get broken inside the hole.
In order to prevent sticking, the exhaust manifold studs are treated with MODENGY 1001 anti-friction solid-film coating based on molybdenum disulfide and graphite before mounting.
A thin lubricating layer of the coating prevents direct contact between the threaded parts, and provides effective protection against seizure, scores, and sticking even after the engine have been operated for a long while.
This product is applied out of an aerosol can, and cures quickly at room temperature. The studs are ready to be used in 15 minutes after applying the coating.
Use of MODENGY 1001 anti-friction solid-film coating enables to remove a nut, or to unscrew a stud out of the cylinder block easily preventing seizure, scores, and threaded connection sticking.
