The dip spinning process is used for the cost-effective coating of bulk materials with a zinc flake layer.
During dip spinning the small components that are to be coated are dipped into the immersion bath. Then the excess material is spun-off in a drum. The wet film is dried and cured (baked). Depending on the required degree of protection, a further protective layer is applied.
Zinc flake coatings are free of chromium (VI). Specially developed combination layers are used to achieve good non-stick properties and optimise sliding properties. Zinc flake coatings are primarily used in the automotive industry as well as for applications where excellent corrosion protection is to be combined with other functional and decorative properties.
Delta MKS®
- Powerful corrosion protection with zinc flakes
Delta MKS
® is a corrosion protection coating system applied with the
most modern application methods - dip spinning, dipping and fully automatic wet
spraying.
The surface treatment is free of chromate (Chromium-VI), and the zinc flakes
provide galvanic protection. Hydrogen-induced corrosion, occurring when zinc is
applied with electroplating, is not an issue. Sealing systems developed
specifically to complement the functionality enable good sliding and nonstick
properties.
Delta MKS® coating systems are mainly used in the automotive
industry and in applications where outstanding corrosion resistance has to be
combined with other functional and decorative requirements of international
automotive manufacturers.
Coating thickness: 5 µm to 30 µm (depending on coating specification)
antifricor®
- Multifunction solid lubricant
With antifricor
®, Impreglon offers an approved combination system to
optimize friction, wear and lubrication of moving components. Reduced friction
with antifricor® leads to a longer serviceable life (Refer to the illustration
below).
antifricor® is suitable for all applications in which friction
reduces functionality and durability of components. Wear resistance, dry
lubrication and corrosion protection are combined effectively in one coating
system.
antifricor® is used by almost all automotive manufacturers.
Typical parts are hinges, door locks, door stays, door handles, adjustment
systems, fittings and other fasteners.
