Hard Ematal coating
EMATEF® is an extremely low-porosity aluminium oxide coating containing titanium and impregnated with Teflon® that is produced through a special anodising process.
It provides very good protection against wear and corrosion. The minimal coat layer allows production to final dimensions. The Teflon® impregnation additionally increases the slip and non-stick properties of the surface.
Coat thickness and composition
EMATEF® is suitable for coat thicknesses ranging from 10 to 25 µm, depending on the aluminium alloy used. The recommended coat thickness is 15 µm. 80% of this layer thickness ‘grows’ into the base material, resulting in an application of 3 µm.
The tolerance range of an EMATEF® coat is ± 4 µm depending on the material used and the selected coat thickness.
The colour of a component coated with EMATEF® depends on the alloy, the coat thickness and the type of processing. The colour spectrum ranges from light grey to bronze.
EMATEF® cannot be dyed.
