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
