Description
For bonding cylindrical joining parts, especially with narrow bonding gaps up to 0.25 mm (0.01″). Fast curing on all metals, including passive metals such as stainless steel.
LOCTITE® 638 is a joining adhesive that provides high strength on all metals, including passive metals. The product offers high temperature performance and good oil tolerance, a hand strength of just four minutes and achieves a gap fill of 0.15mm to 0.25mm (0.006″ to 0.01″). LOCTITE® 638 also tolerates minor contamination of surfaces, e.g. by industrial oils. The highly viscous product is ideal for shafts, gears, pulleys and similar cylindrical parts. The operating temperature is between -55 °C and 180 °C (-65 °F and 355 °F).
- Ideal for shafts, gears, pulleys and similar cylindrical parts
- High strength on all metals, including passive metals (e.g. stainless steel)
- High temperature resistance
- Fluorescent under UV light for quality control
