Composition
· Solid lubricants
· Organic binder
· Organic solvent
Instructions for application
· Parts must be cleaned and degreased thoroughly before coating
· Improved adhesion on the surface by : sandblasting and/or phosphatizing
· Coating must be stirred well before use
· High economic efficiency thanks to very low consumption (1 kg is sufficient for a surface of up to 20 m2)
· Application by spraying, dip centrifuging or tumbling
· Application on hot surfaces (120 °C) is possible
· Curing time at 200 °C : object temperature approx. 30 minutes
· Curing time at 130 °C : object temperature approx. 60 minutes
· Optimal thickness of coating: approx. 10 – 30μm
· Recommended diluting agent: AFC Solvent PMA
· Kinematic viscosity at 20 °C, nozzle 4 mm 17 – 20 s (DIN 53211 *)
Shelf life
· At least 24 months from date of production when stored at ambient temperatures (approx. 20 °C) in the original sealed container
