Condorcoat K75 is believed to be the only finish that replaces
traditional multi-stage zinc phosphate in cold forming.
The process is straightforward and safe, extremely bonding
and efficient also for extreme deformation.
Condoroil’s research for an alternative product to zinc
phosphate has been performed in order to propose a short
and efficient process and, above all, a harmless product.
With Condorcoat K75 the required steps for the material
preparation, pickled or sand blasted, are reduced from the
traditional four (activation, phosphating, rinse and calcination)
to just one step and therefore easily insertable in line with
the cold forming process itself.
No rinse nor final neutralisation are required; this
makes the water purification plant unnecessary while the
different nature of the conversion product eliminates the
necessity to have a filtering and/or sedimentation plant in
the phosphating tank. This means a reduction in the plant
and management costs for water treatment and sludge
disposal.
The chemical reaction on the metal makes the product
bonding and efficient also for extreme deformation, on the
contrary of a deposit which is bonded only physically to
the material, as in case of non reactive salts, which cannot
stand the tensions related to the most extreme deformations
especially on steel with high carbon content.
The product is stable towards the acid drag outs from the
previous pickling tanks. The drag outs cause balance
problems in the acidity ratio in a phosphating bath (and even
more in a bath with non reactive salts) and determine the
formation of a defective coating.
The product leaves such a roughness that makes the soaps
and lubricating oil seizing easier. The dry deposit provides
corrosion resistance in case the working does not follow
immediately the treatment.
The deposit, when dry, is stable to humidity. In fact, a
deposit too sensible to humidity could hydrate causing rust
problems as well as reduction of the performance in the die
due to interaction of water with oils and lubricating oils.
