To free seized or corroded assemblies, Loctite Freeze and Release, a low-viscosity, spray-on lubricant, is designed to shock-freeze metal parts, allowing lubricating oils to penetrate into rust layers. Loctite Freeze and Release instantly freezes seized and rusted parts to – 45ËšF, allowing hairline cracks to form in the rust layer as the metal contracts. These cracks allow the product’s lubricating oil to penetrate into the rust layer efficiently by capillary action. After 1 – 2 min., the assembly is easy to dismantle. Loctite Freeze and Release eliminates the need for cutting torches and die grinders. The product is available in a 400-mL aerosol can. — Henkel, Corp., Rocky Hill, Conn.
