WHY METALLIC BONDING
Metallic Powder Coatings can be produced to give a range of metallic finishes from silver
to gold and with all ranges of gloss and profile. By adding Aluminium, Bronze, Zinc,
Magnesium and Stainless steel pigments to the thermosetting Powder Coatings.
The most used pigment for silver metallic effect is Aluminium 1-2% in the leafing and
3-5% in the non-leafing form. With Aluminium pigments the fine Leafing grades will
produce the brightest silver and glossy effects these are the lower average particle size.
(4-12 microns) The Non- Leafing are higher average particle size (10-20 microns) and give
a sparkle effect.
Smooth Metallic effect Powder Coatings cannot be produced using the normal powder
coating process because the shear forces that occur during extrusion distort the metallic
particles causing them to loose their lustre. The extrusion process can produce some
excellent bright hammer finish effects but on the whole they tend to be silver and dark grey
effects.
