Molybdenum disulfide
LOCTITE® LB 8191 is a quick-drying molybdenum disulfide lubricant coating with excellent protection against corrosion, friction, seizing, and more. It can be easily applied with its spray dispense method on metal hinges, slipways on conveyor equipment, and more, forming a dry film lubricant that enhances the performance of oils and greases and improves tool service. LOCTITE® LB 8191 resists temperatures up to 340°C and prevents the accumulation of dust or dirt on equipment surfaces.
Poor lubrication of machining parts
Premature damage and wear to equipment parts
High-temperature seizing of equipment parts during operation
Hinges, slipways on conveyor equipment, and more
