About the product

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).
