Application and Packaging Specifications
■ When replacing existing lubricants, thoroughly clean the components before application.
■ Avoid contact with alkali metals (such as sodium or potassium) and highly reactive fluorinating agents.
■ Decomposition may occur at extremely high temperatures (above 300°C); do not exceed the recommended operating temperature.
■ Use in a well-ventilated area and avoid prolonged inhalation of vapors.
■ Prevent contamination by dust, moisture, or other foreign substances during use.
■ Store in a tightly sealed container in a cool and dry place.
■ The product can be applied by dripping, brushing, dipping, or spraying to achieve uniform coverage.
■ The recommended dosage should be adjusted according to operating conditions such as speed, load, and temperature. Avoid over-application.
■ For sealing systems or precision components, a thin film lubrication method is recommended.
■ For high-temperature or vacuum applications, pre-testing is recommended to confirm suitability.
