Highlights
Avoiding burn-in defects
The superior refractoriness of VELVACOAT coatings for iron and steel castings makes it
an exceptional solution for avoiding burn-in defects. VELVACOAT prevents the chemical
reactions that cause this defect. VELVACOAT is a highly protective barrier between sand andmolten metal.

Zircon-free coatings for heavy iron and steel applications
ASK Chemicals has developed an innovative zircon-free refractory combination for heavy
and thick-walled iron, as well as steel castings. In such extreme applications, it provides thesame or even better casting results as achieved with coatings containing zirconium. Two key
advantages of zircon-free coatings include low density and material handling.

MIRATEC
Innovative coatings for serial casting production
MIRATEC water-based coatings are the highest performing in their class. When applied using thedipping method, MIRATEC is ideal for automotive applications, as it has the shortest cycle times.
MIRATEC coatings provide an even coating layer especially with complex core packages or challenging
core geometries. Thanks to its engineered formulation and tailored characteristics (e.g. gas permeability), the innovative coating technology reduces casting defects and provides an excellent surface finish.

SOLITEC
Water-based coatings for brushing, spraying or flow coating application
SOLITEC coatings are highly recommended for flow coating big and / or complex geometries. SOLITEC
coatings impress with the shortest drying times in their application area. The coating is offered in several
innovative color-changing formulations that represent a visual wet / dry-indicator. This unique characteristic
ensures the integrity of the coating within the production process. Additionally, high performance formulations (e.g. zircon-free, sulphur stop, burn-in barrier) vastly improve the surface finish, which leads toreduced cleaning costs.

Benefits• Short air-drying time and enhanced
refractoriness• Excellent application properties• Fewer casting defects and excellent
casting surfaces

coatings

CERAMCOTE
The multifunctional high-performing water-based coating
CERAMCOTE coatings were specifically designed for the Lost Foam and Full Mold technologies. A staple within
the industry, CERAMCOTE provides superior performance and consistency to the automotive and non-automotive markets. Utilizing a special proprietary formulation, ASK Chemicals has optimized the rheological properties of CERAMCOTE (i.e. viscosity and layer thickness). Stable viscosity determines the evenness of the coating
layer to prevent casting defects such as metal penetration, burn-on defects, cracks and scabs. CERAMCOTE
offers superior bond strength and ductility. The dried coating can withstand even the most severe mechanicalstress during sand compaction. This coating line is available for the following application methods: brushing,spraying, flow coatings and dipping.

Benefits• Tailored permeability and insulating characteristics• Adopted strength, ductility (dried coating)and rigidity

Image:
Lost Foam mold forthe automotive industry

Highlights

CERAMCOTE coatings offer excellent insulating characteristics
Thanks to its formulation, the dried coating layer of CERAMCOTE lost foam coatings
offers excellent insulating characteristics. Together with the fact, that the gas permeability canbe controlled on a high or low level, these are ideal pre-conditions for the production ofthin-walled casted parts.
