The formulation is designed to improve assembly and disassembly of fasteners, studs, bolts and flanges by establishing a stable lubricating film that resists chemical attack and extreme heat. With a lower temperature rating down to -20°F, it works in both cold starts and high-temperature operating environments.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this anti-seize protect metal parts during high heat?\u003c\/h3\u003e\n\u003cp\u003eLoctite's copper particles form a sacrificial barrier between mating surfaces while graphite adds solid-film lubricity.
