WEDOLiT AW 8321 is universally applicable for parts cleaning and corrosion protection. The mineral oil free product is not only suitable for steel, but also for non-ferrous metals. Utilizing the latest technology, AW 8321 offers the possibility for a boron and formaldehyde free application.
WEDOLIT K 91 is a temporary corrosion protection agent. WEDOLIT K 91 is a soft paste and it builds with
water milky-disperse emulsions. To protect the parts WEDOLIT K 91 is applicable as aqueous solution in
dipping- or spraying processes. Contrary to the dipping process the spraying process is to prefer, when
the application should also obtain a cleaning effect. By application of WEDOLIT K 91 in dipping processes a
heating of the emulsion to approximately 50°C is advantageous. The sojourn time of the parts in the
immersion bath should be minimum 2-4 minute. The run-off time over the immersion bath is
also 2-4 minute.
By application of a 25% emulsion of WEDOLIT K 91 a slight greasy film with a layer weight of
approximately 2 g/m² remains on the treated surface after evaporation of the water.
The corrosion protection under a roof corresponds with a middle corrosion protection agent based on
solvents. When a lower corrosion protection is sufficient the concentration of the emulsion, i.e. the layer
weight can be reduced.
WEDOLIT K 91 is also applicable as cleaning- and washing emulsion in aqueous solution with a
concentration of 10%.
