Composition
· PTFE
· Organic binder
· Solvent : Water
Instructions for application
· Parts must be cleaned and degreased thoroughly before coating
· Improved adhesion on the surface by : sandblasting and/or phosphatizing
· Adhesion improvement on the plastics is achieved through: degreasing, pre treatment using a primer, plasma or a corona
· Coating must be stirred well before use
· Application by spraying, dipping or brushing
· Drying time in air : approx. 20 minutes
· Drying time accerelated at 40 °C : approx. 5 minutes
· Spraying conditions e.g. : 0.8 mm nozzle, 2 bar spray pressure 30 cm spraying distance to component surface
· Optimal thickness of coating : approx. 5 – 20 μm
· Recommended diluting agent : water
Shelf life
· At least 18 months from date of production when stored at ambient temperatures (approx. 20 °C) in the original sealed container
