Loctite 638 High Strength Fast Cure Retaining Compound

<P><STRONG>Loctite 638 </STRONG>has been designed for the <STRONG>bonding</STRONG> of <STRONG>cylindrical fitting parts</STRONG>, particularly where bond gaps can approach 0.25mm. It cures when confined, in the absence of air, between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration.</P><P>Loctite 638 not only works on active metals but also on passive substrates, exhibiting robust cure performance. It offers high-temperature performance and good oil tolerance, and tolerates minor surface contaminants.</P>
