RELEASE AGENTS AND LUBRICANTS FOR HIGH PRESSURE DIECASTING

In over 100 years that began as a lubricant-dealer, Geiger + Co. SchmierstoffChemie GmbH has developed into a leading producer of high-quality release agents and lubricants for die casting. Located since the beginning in Heilbronn, our headquarters have always been adapted and modernized to current needs. “To stay on the ball” and the constant determination to produce a better product has been our recipe of success for years.

WLG 20/6

Form liquid

Colour black

Application area

Mikrocollid WLG 20/6 is a water-soluble graphite concentrate for use in
light metal and heavy metal die-casting.

It is to be diluted with tap water.

Mikrocollid WLG 20/6 is applied in a dilution of approx. 1:20 to 1:40 or above with water (best dilution ratiois to be ascertained individually in compliance with technical casting conditions).
After evaporation of the water, a uniform and well adhesive film is formed.

Coating is normally done once or twice.

The excellent heat conductivity of Mikrocollid WLG 20/6 causes an advantageous heat exchange between product and die-mould.

Mikrocollid WLG 20/6 stops soldering of metal to die and, by this,
facilitates output of castings.

Mikrocollid WLG 20/6 reduces surface unevenness of moulds and cores
and contributes considerably to smooth surfaces.

Mikrocollid WLG 20/6 avoids early erosion of die-moulds caused by
metal flow and therefore prolon

Graphite-free
  • WLK 40/15
  • 770 WL Löffelschlichte
WLK 40/15

Form liquid

Colour white

Application area

Water-miscible, graphite-free insulating layer with a solid content of
approx. 40% is applied in the mixture ratio of 1 : 3 to 1 : 10 to the thoroughly cleaned and grease-free mould through spraying or immersion.

The mould temperature should be at least 150° C but not exceed 300° C
in order to achieve immediate adhesion and to avoid bubbles forming.

The particle size of the solid material was selected in such a way as to
achieve a perfect metal flow with an essentially smooth surface for the
wide range of castings (various wall thickness).

Graphite finishes which are used in conjunction with Mikrocollid WLK
40/15 take quickly within a wide temperature range and provide reliable
adhesion.

The low heat conductivity of Mikrocollid WLK 40/15 reliably prevents the
metal giving off heat too quickly to the mould.

770 WL Löffelschlichte

Form liquid

Colour white

Application area 

Mikrocollid 770 WL Löffelschlichte is a water miscible, graphite-free
insulating layer with a solid content of approx. 40%.

It is applied to the cleaned, grease-free and cold mould bucket by spraying, immersing or painting.

The product is supplied ready for use.

Mikrocollid 770 WL Löffelschlichte should not be stored at temperatures
> 40°C otherwise this may lead to a premature, unwanted hardening of the
product.

The low heat conductivity of Mikrocollid 770 WL Löffelschlichte reliably reduces any excessively rapid heat dissipation from the metal and consequently improves the quality of the cast melting.

Maintenance work and down times can be reduced through the use of
Mikrocollid 770 WL Löffelschlichte.
