Detailed product description

Product Introduction

Loctite 638 is designed for the bonding of cylindrical fittings, especially where key gaps can approach 0.25 mm Maximum strength at room temperature is required. The product cures shock and vibration when enclosed between tightly fitting metal surfaces and prevents loosening and leakage without air. Loctite 638 provides powerful curing properties. It is not only suitable for active metals such as mild steel, but also for passive metals such as stainless steel and substrates such as plated surfaces. Products offer high temperature performance and oil resistance. It tolerates minor surface contamination from a variety of oils, such as cutting, lubricating, anti-corrosive and protective fluids. Typical applications include locking bushings and sleeves to housings and shafts.
