Description
LOCTITE 638 is designed to hold cylindrical components, particularly where welding gaps approach 0.25 mm. The product polymerizes when air is enclosed between applied metal surfaces and prevents loosening and leaks due to vibrations and vibrations. It works not only on active metals, but also on passive substrates, presenting a strong hardening performance. The product offers high temperature efficiency and good oil resistance, also resistant to small-scale surface pollution.
