MIRATECTM TS

WATER-BASED TOP SURFACE COATINGFOR HIGHLY PRODUCTIVE AUTOMOTIVECASTING
The production of complex castings is essential to themodern automotive industry. The demands on thecomponents are becoming more and more specific:
lighter, stronger, or even bionic structures. Bionicstructures, in particular, offer the advantages of using
less material, reducing weight, and thus saving processenergy while maintaining structural strength.
Since it is impossible to treat filigree geometries with ablasting process, the use of coatings is subject to highrequirements to produce absolutely flawless castings withminimum coating residue. In particularly complex cases,
investing in a special washing machine to meet OEM
requirements may even be necessary, which reduces
productivity and entails investment costs.
The MIRATECTM TS coating series is the solution to thesechallenges faced by iron casters. Specifically, MIRATECTMTop Surface Technology provides excellent protective
properties against casting defects and contains special
peel-off additives that promote the detachment of thecoating.

TECHNOLOGICAL ADVANTAGES▪

Reduced residual dirt in the component▪

Avoidance of veining, penetration, and gas-related
casting defects▪

Short handling time▪

Improved microstructure with vermicular graphite▪

Quick drying with built-in color change

MIRATECTM Top Surface Technology
Top Surface Technology has been specially developed forautomotive foundries. The formulation has a special peel-off
effect, which causes the coating to peel off the cast part byitself after casting, solidification, and cooling. It leaves
behind a very clean and almost residue-free casting.
The peel-off effect of MIRATECTM TS has been proven in
SEM investigations. The scanning electron microscope
images clearly show that the coating leaves a very clean
and almost residue-free cast surface (Figure 1).
Higher productivity and lower costs withTS Technology
The coating technology features rapid drying with a color
change that shows the drying progress.
This visual indicator allows the user to easily see when thecoating is completely dry. This saves time and energy andsaves drying costs.
The water-based coating is particularly suitable for dipping
applications and leaves practically no drops after drying.
The coating also helps to reduce rework and cleaning time,
as it reduces residual dirt and avoids casting defects suchas veining and penetration.The improved microstructurewith vermicular graphite increases the quality of the casting.
Overall, MIRATECTM TS contributes to higher productivity
and better quality at lower costs.
The TS versions are also available as an LFS version for
reduced formaldehyde pollution in core production ifrequired.
Global quality improvement
Foundries all over the world are now using MIRATECTM TS
coatings to produce complex parts economically. A wide
variety of climatic conditions, sands, and binders do notinterfere with the peel-off effect of the MIRATECTM TS
coating. It works in a wide variety of conditions (Figure 2).
