Loctite 638
LOCTITE® 638 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.25 mm. Ideal for use where high dynamic forces or cyclic loading is expected, for eg: shafts, gears, pulleys and cylindrical parts that
- High Strength (4200 Psi)
- Fills Gaps Upto 0.25mm
- 180oC Service Temperature
- High temperature resistance
- High strength on all metals, including passive substrates (e.g. stainless steel)

- Prevents loosening: It fills all gaps between the cylindrical components and cures into a hard thermoset plastic. This unitizes the assembly and prevents loosening and leakage from shock and vibration
- Works on all metal substrates
- Tolerant towards minor surface contaminations
