Product Information

The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration.

It not only works on active metals but also on passive substrates, exhibiting robust cure performance. The product offers high-temperature performance and good oil tolerance, and tolerates minor surface contaminants.

Features:

Tolerates minor contaminants, including industrial oils
High strength on all metals, including passive substrates (e.g. stainless steel)
High temperature resistance
Ideal for shafts, gears, pulleys and similar cylindrical parts
