Loctite 638 Glue – Product introduction, usage and storage

Loctite 638 is designed for the bonding of cylindrical fittings, particularly where gaps of approximately 0.25 mm are present and maximum strength at room temperature is required. The product bonds when confined in the absence of air between close metal surfaces and prevents loosening and leakage from shock and vibration. Typical applications include fastening fasteners and sleeves to housings and on shafts. Loctite 638 provides strong adhesion. It works not only on active metals (e.g. mild steel) but also on passive surfaces such as stainless steel and plated surfaces. Loctite 638 offers high temperature performance and oil resistance. It tolerates minor surface contamination from various oils, such as cutting, lubricating, anti-corrosion and protective fluids. This will create a tight fit between shafts and cylinders of machinery and engines. Absolutely prevents loosening and leakage from mechanical impacts.

When should Loctite 638 glue be used ?

You can use loctite 638 glue to prevent thread stripping or to seal gaps.

With the main function of anti-rotation as above, loctite 638 glue is often used mainly for prevention. This will create more safety for machinery and equipment than when you let the machine break down before reinforcing it.

Loctite 638 has high load-transfer and tensile strength, and can withstand shear forces up to 4,500 psi(31). It can also fill gaps up to 0.015”(0.38 mm) in diameter.

Loctite 638 glue has a heat resistance of up to 300ºF(150C)º. Suitable for use in the internal engine of the machine.

Loctite 638 glue can also fix joints on steel in 4 minutes. With normal machines, the glue will dry in about 10 minutes and completely dry in 24 hours.

Instructions for using Loctite 638 glue

For best results, clean surfaces (inside and outside) with cleaning solvent and allow to dry. To speed up the bonding process or have large gaps, use primer and allow to dry.

For assembly, apply adhesive around the leading edge of the pin and inside the pin neck and use a rotating motion during installation to ensure best fit.

For press-fit assembly, apply glue thoroughly to the reverse side and assemble at high compression level.

For compact assembly products, the adhesive must be applied to the part to create a smooth film of material. If the center is heated for assembly, attach the battery. If the battery is cooled for assembly, apply the main host. If both heating and cooling are performed, apply the material to cool the part. Avoid condensation on the cooling parts.

Notes on product use and storage

Loctite 638 glue can dry within 10 minutes and can shrink the glue surface within 4 minutes. Therefore, when not using the product, you need to close the lid tightly. Make sure that oxygen does not come into direct contact with the product for a long time. Because this can reduce the main quality of the product.

When using loctite 638 glue to lock welds, screws, and threaded parts. You should use a moderate amount. Avoid using too much, which is both wasteful and increases the bonding time of the product.

Store product in a cool, dry place.
