Retaining Compound – high strength. General purpose. quick hardening. LOCTITE 638 is intended for the bonding of cylindrical fitting components, significantly wherever bond gaps will approach zero.25 mm. the merchandise cures once confined within the absence of air between snug metal surfaces and prevents loosening and outpouring because of shock and vibration. It not solely works on active metals however additionally on passive substrates, exhibiting sturdy cure performance. the merchandise offers high-temperature performance and smart oil tolerance, and tolerates minor surface contaminants.
High temperature resistance
Tolerates minor contaminants, together with industrial oils
High strength on all metals, together with passive substrates (e.g. unsullied steel)
Ideal for shafts, gears, pulleys and similar cylindrical components
