0.25 – 2.5 %VEINO
Organic and renewable additives
Our organic and renewable VEINO line is a high-performance additive with an extremely low addition rate.
This reduced additive consumption level is the lowest in our portfolio and thus leads to cost savings.
Performance remains unaffected and the flowability rate of VEINO, which leads to good core compaction, is exceptional. All things considered, VEINO offers quality, performance and minimal investment – anexcellent choice for most applications.

Benefits• Prevents veining• Improved casting surface• Excellent dissolution• Not soluble in water• 100 % renewable raw material

Creating space with organic components
During casting, the metal heat burns out the starch particles within VEINO. This creates spacefor silica sand to fill during expansion. This unique compaction method ultimatelyhelps to reduce veining defects. This also reduces cleaning room costs (i.e. fettling costs)
due to higher quality castings with excellent surface finish characteristics.

ISOSEAL
Environmentally friendly additives
This unique inorganic additive family is the coating-free version our portfolio. A significant cost saver, given
the correct circumstances you may eliminate coating use within your process entirely. Additionally, theuse of special minerals counteracts sand expansion, thereby allowing for greater compaction.

Benefits• Prevents veining and penetration• Improved casting surface finish• Saves cleaning room (i.e. fettling) costs• Low resin demand• Environmentally friendly (no emissions)

The science behind coating-free additives
ISOSEAL additives make the bold claim that they eliminate the need for a coating – thiswould naturally lead to significant cost savings. ASK Chemicals engineers and researchers
have accomplished this feature by formulating ISOSEAL to act as a buffer during the quartz
expansion in the pouring process. This creates a barrier layer between the sand grains as a
coating itself.

VEINO ULTRAHigh-performance hybrid additives
When developing the VEINO ULTRA additives line our objective was to combine the advantages of both
inorganic and organic technology into one environmentally friendly high-performance hybrid additive. The result has proved successful: gas emissions have been reduced, greater surface finish and casting defects
have been eliminated. In addition, the possibility of uncoated casting production is now realistic thanks toVEINO ULTRA additives, as is the partial / full substitution of expensive specialty sands.

Benefits• Prevents veining and penetration defects• Improves surface finish• Lower gas emissions than organic varieties• Minimal effect on tensile strength• Potential for coating-free application

Our recommendation: VEINO ULTRA 4874
VEINO ULTRA 4874 is the performer in our VEINO ULTRA family. Ultimately, its full potential
can be seen best in cold box and PEP SET applications. Most notably, this hybrid additive isextremely effective in preventing casting defects, as well as providing anti-veining effects.
VEINO ULTRA 4874 is primarily used in uncoated casting. Here, it has demonstrated positive
results in the series production of brake disks and differential housings.
