LOCTITE 638 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.25 mm and where maximum strength at room temperature is required.
The product offers high-temperature performance and good oil tolerance, and tolerates minor surface contaminants. It 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.
High temperature resistance
Tolerates minor contaminants, including industrial oils
High strength on all metals, including passive substrates (e.g. stainless steel)
Ideal for shafts, gears, pulleys and similar cylindrical parts
