Fibre Adhesive Locktite 638 50 ml
The Loctite 638 Fibre Adhesive is specifically formulated to secure cylindrical fitting parts, ensuring maximum strength and reliability. It is designed to bond active metals (like steel) and passive substrates, delivering consistent holding power even under dynamic loads.
Superior Performance Under Stress
Loctite 638 withstands high temperatures up to 180 °C, resists vibration, shock, and chemical exposure, and cures quickly to form a durable bond. It fills gaps up to 0.25 mm, making it suitable for worn or loose fitting parts.
Ideal for Industrial and Workshop Use
Perfect for use in mechanical workshops, automotive repair shops, and manufacturing environments. Common applications include locking bearings into housings, securing gears on shafts, and repairing worn keyways.
| LOCTITE® 638™ is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.25 mm and where maximum strength at room temperature is required. |
| The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. |
| Typical applications include locking bushings and sleeves into housings and on shafts. |
| LOCTITE® 638™ provides robust curing performance. It not only works on active metals (e.g. mild steel) but also on passive substrates such as stainless steel and plated surfaces. |
| The product offers high temperature performance and oil tolerance. |
| It tolerates minor surface contaminations from various oils, such as cutting, lubrication, anti-corrosion and protection fluids. |
