MOLYKOTE® M-77 Assembly Paste is a MoS₂ and graphite-based, high-temp dry film lubricant. Provides excellent protection against wear, seizure, and galling up to 400°C. Ideal for bolts, flanges, bearings, and sliding parts in heavy-duty and high-heat environments.
DuPont™ MOLYKOTE® M-77 Assembly Paste is a premium dry film lubricant designed for high-temperature, high-load assembly applications. Formulated with molybdenum disulfide (MoS₂) and graphite solid lubricants, it reduces friction and prevents wear, seizure, and fretting on metal surfaces.
M-77 creates a durable, heat-resistant, dry lubricating film that ensures effective protection even when conventional oils and greases fail. With stability up to 400°C (short-term 600°C), it is ideally suited for slow-moving, heavily loaded systems.
