LUGALVAN DC

LUGALVAN DC is an aqueous emulsion of an ethylene copolymer that is commonly applied to metal surfaces to improve resistance to corrosion and to improve aesthetic appearance.
LUGALVAN DC is ingredient of transparent protective coatings for use in the electroplating industry.
LUGALVAN DC is wax emulsion for the production of transparent anti-corrosion coatings.

The usage of LUGALVAN DC forms films which adhere well to metal.
LUGALVAN DC is especially effective on chromated, zinc-plated parts and LUGALVAN DC also reduces the tendency of chromium(VI) ions to be leached out.
LUGALVAN DC can be used to prevent nickel and other metals from tarnishing, and LUGALVAN DC can be applied as a decorative coating to non-ferrous metals.

Applications of LUGALVAN DC:
LUGALVAN DC is applied to metal surfaces to improve their resistance to corrosion and their aesthetic appearance.
LUGALVAN DC forms films which adhere well to metal.

LUGALVAN DC is especially effective on chromated, zinc-plated parts.
LUGALVAN DC also reduces the tendency of chromium(VI) ions to be leached out.

LUGALVAN DC can be used to prevent nickel and other metals from tarnishing, and LUGALVAN DC can be applied as a decorative coating to non-ferrous metals.
LUGALVAN DC does not contain an emulsifier.

LUGALVAN DC is miscible with water in all proportions, provided the pH does not fall below 8.5.
Experience has shown that LUGALVAN DC can be advisable to add ammonia or amines such as dimethylethanolamine to maintain the pH at around 9 in order to prevent precipitation.

On metal surfaces, LUGALVAN DC forms a corrosion-protective film with good adhesive capacity that enhances the appearance of the sealed products.
LUGALVAN DC can be applied to zinc-plated steel (passivated or not passivated) and to ungalvanized steel, nickel, aluminium and non-ferrous metals.

Basically, LUGALVAN DC is possible to apply LUGALVAN DC to other metals, this must, however, be tested on a case-by-case basis.
LUGALVAN DC enhances the corrosion protection of metal surfaces regardless of the type of pre-treatment.

LUGALVAN DC is available as an aqueous, emulsifier-free polymer emulsion, which is miscible with water in all proportions, provided the pH value does not fall below 8.5.
Experience has shown that LUGALVAN DC may be advisable to adjust the pH value at around 9 by adding ammonia or amines, e. g. dimethylethanol amine, in order to prevent precipitation of LUGALVAN DC.

The corrosion resistance of sheet metals treated with LUGALVAN DC can be further enhanced by adding silicates.
If LUGALVAN DC is applied to copper or alloys containing copper, LUGALVAN DC may be required to add benzotriazole, to prevent corrosion during application when LUGALVAN DC is wet.

LUGALVAN DC can be applied by dipping, spinning or spraying.
For spraying applications, a solids content of > 10% is recommended.

The thickness of the polymer film can be adjusted via the viscosity.
The viscosity basically depends on the solids content of the coating bath but also on the pH value.

At pH values above 9.5, the viscosity will decrease.
Usually, films of ca. 1 µm are formed from coating baths with a solids content of 5%.

Higher film thicknesses can be achieved through a higher solids concentration or multiple dipping with intermediate drying.
To achieve constant film thicknesses, LUGALVAN DC is required to monitor the solids concentration in the coating bath.

Depending on the thickness of the film, LUGALVAN DC can be advisable to use higher temperatures for the drying process.
Depending on size and geometry the parts can be dried within one minute at 80°C (fan heater); higher temperatures will reduce the drying time.

LUGALVAN DC can be pigmented by mixing LUGALVAN DC with Luconyl or Dispers pigment preparations.
The components can be mixed by simple stirring and do not require a complicated mixing procedure.
Films produced from LUGALVAN DC are ductile and insensitive to the deformation of the substrate.

Handling of LUGALVAN DC:
LUGALVAN DC should be prevented from coming into contact with the eyes and skin.
Safety glasses should be worn when handling LUGALVAN DC in its undiluted form.
Further information is given in our Safety Data Sheet.

Storage of LUGALVAN DC:
The freeze-thaw stability of LUGALVAN DC is very good.
LUGALVAN DC viscosity can undergo a slight, gradual increase during storage.

We would recommend filtering it if LUGALVAN DC has been stored for a long time or if a crust has formed.
LUGALVAN DC has a shelf life of one year, provided LUGALVAN DC is stored properly.

Being an aqueous emulsion, LUGALVAN DC has a good freeze-thaw stability.
The viscosity may slightly increase during storage.

In case of prolonged storage and crust formation due to volatilisation of water, LUGALVAN DC is recommended to filter LUGALVAN DC before usage.
Keep container tightly closed and store LUGALVAN DC in a cool location.
LUGALVAN DC has a shelf life of at least one year, provided LUGALVAN DC is stored properly in originally sealed drums.

Safety of LUGALVAN DC:
We know of no ill effects that could have resulted from using LUGALVAN DC for the purpose for which LUGALVAN DC is intended and from processing it in accordance with current practice.
According to our information and experience, LUGALVAN DC does not exert any harmful effects on health, provided that LUGALVAN DC is used properly, due attention is given to the precautions necessary for handling chemicals, and the information and advice given in our Safety Data Sheet are observed.

Disposal of LUGALVAN DC:
LUGALVAN DC can be cleaned from coating equipment with aqueous, alkaline cleaners after LUGALVAN DC has dried.
The polymer can be removed from waste water by adjusting its pH so that LUGALVAN DC is slightly acid.
The precipitate can then be filtered out.
