PTFE coating has excellent chemical stability and corrosion resistance, can withstand most chemicals, and is widely used in various scenarios that require acid, alkali and organic solvent resistance.
Traditional lubricants have problems of diffusion and pollution. The PTFE coating can form a uniform lubricating film on the surface of the workpiece, which has the characteristics of high cleanliness, low torque lubrication, noise reduction, and anti-static.
Even very thin film coatings show good non-stick properties.
The surface treated by PTFE coating can produce dry lubrication, and its friction coefficient can be as low as 0.05. When processing mechanical parts, PTFE coating can produce self-lubricating effect while reducing friction coefficient and increasing wear resistance.
In a wide frequency range, PTFE coating has high dielectric strength, low dissipation factor and very high surface resistivity.
PTFE coating shows excellent adhesion to various metal substrates, thereby protecting the coating from falling off under the action of the external environment, such as seawater immersion and atmospheric erosion.
The insulation strength of the PTFE coating can reach 500-1200 volts per microinch (MIL), so as to achieve the effect of inhibiting electrochemical corrosion.
For specific purposes, the PTFE coating can be prepared into different colors to facilitate the management of safety levels and future maintenance.
