Dry Film Lubricant PTFE Molybdenum Disulfide Spray/Brush, for Key Precision Mechanism Plastic Anti-Friction Silencing
This dry film lubricant is a solvent‑borne solid‑lubricant coating blended with finely milled PTFE and molybdenum disulfide powders. It can be applied via spraying or brushing. After solvent volatilization, a thin, non‑oily dry lubricating film remains on component surfaces. The composite solid‑lubricant layer reduces sliding friction, suppresses mechanical rattling noise, and offers anti‑wear protection for precision mechanisms and plastic parts.
Product DetailsDry Film Lubricant PTFE Molybdenum Disulfide Spray/Brush, for Key Precision Mechanism Plastic Anti‑Friction SilencingThis dry film lubricant consists of volatile solvent system, evenly dispersed PTFE and molybdenum disulfide solid particles together with film‑forming agents and anti‑oxidant additives. Before curing, the liquid formulation allows two application methods: spray for large‑area uniform coating and brush for localized, narrow or intricate precision parts. Once the solvent completely evaporates, a continuous, dry, non‑tacky solid lubricating film adheres firmly onto substrate surfaces. No residual oily layer remains after drying, which avoids contamination of surrounding assemblies.
When coated on moving surfaces of precision mechanisms and plastic components, the composite solid‑lubricant film delivers a low‑friction sliding interface. PTFE improves slip performance for plastic‑on‑plastic and plastic‑metal mating pairs, while molybdenum disulfide provides anti‑wear reinforcement under moderate local contact pressure. The dry film absorbs micro‑vibration generated during reciprocating motion, effectively eliminating clicking and rattling noise inside precision assemblies.
After film formation, the lubricating coating exhibits good shear‑resistance under repeated sliding movement. The formulated film‑forming agent inhibits premature peeling off during continuous mechanical cycling. Careful raw‑material selection minimizes the risk of chemical attack, swelling or stress cracking of most engineering plastic substrates.
It is suitable for surface lubrication treatment of small precision transmission assemblies, sliding latch components, plastic hinge parts and delicate mechanical modules. Uniform coating thickness is critical. Excessively thick dry film tends to flake and produce loose solid debris which may jam precision moving parts; insufficient film thickness cannot achieve stable low‑friction effect and silencing performance.
Do not mix this dry‑film lubricant with liquid grease or oil‑based lubricants. Contamination by oily lubricants will impair film‑forming capacity and cause premature failure of the solid lubricating layer. Store in tightly sealed original containers inside cool, dry indoor warehouse, keep away from open flame due to volatile solvent. Avoid prolonged high‑temperature storage to preserve suspension stability of PTFE and molybdenum disulfide solids for precision‑mechanism and plastic anti‑friction silencing applications.
