Mikrocollid (Finishes)

Form liquid

Color black

Application 

• 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-mold.
• 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 molds and cores and contributes considerably to smooth surfaces.
• Mikrocollid WLG 20/6 avoids early erosion of die-molds caused by metal flow and therefore prolon

Application

• 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 mold through spraying or immersion.
• The mold 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 mold.

Application 

• 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 mold 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.
