ISOSEAL™
The environmentally friendly additive
This unique inorganic additive family stands as the coating free version within our portfolio. A significant
cost saver, given the correct circumstances you may entirely eliminate coating use within your process.
Additionally, the use of special minerals counteracts sand expansion allowing for greater compaction.
Pressure crushes the minerals and, thus, creates a natural cushion layer along with additional space forthe sand particles to fill.

Benefits• Prevents against veining & penetration defects• Helps improve 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 substantial claim of eliminating the need for a coating – thiswould naturally lead to significant cost savings. ASK Chemicals engineers & researchers haveaccomplished this feat by formulating ISOSEAL™ to act as a buffer during the quartz expansion
in the pouring process. This, in turn, creates a barrier layer between the sand grains and, thus,
acts as a coating itself.

Organic
0.25 – 2.5 %VEINO™
The organic (starch / wood flour) additive
Our organic starch-based VEINO™ line is a high performance additive with an extremely low addition rate.
This reduced additive consumption level is the lowest in our portfolio – leading to cost savings. Better yet,performance remains unaffected. Rather, the flowability rate of VEINO™, leading to good core compaction,is exceptionable. Thus, all things considered, VEINO™ offers quality, performance and minimal investment –an excellent choice within most applications.

Benefits• Prevents against veining & scabbing defects• Excellent shakeout• Not soluble in water(in certain circumstances)• Helps improve casting surface finish
Creating space with organic components
During casting, the metal heat burns out the starch particles within VEINO™. This, in turn,creates space for silica sand to fill during expansion. This unique compaction method ultimately
aids in the reduction of veining defects. Thus, cleaning room costs (i.e. fettling costs) arelike­wise reduced due to higher quality castings with excellent surface finish characteristics.

VEINO ULTRA™ RS Series
The versatile low emissions additive
The VEINO ULTRA™ series is a versatile additive group that accommodates multiple binder types. RS2, forinstance, was specifically engineered for warm box applications. RS4, on the other hand, is ideally suitedto Cold Box & No-Bake technologies. Commonality, between the two, resides in function. Both contain ironoxide for reducing atmospheric conditions that ultimately scavenge gas thereby preventing gas defects.
Additionally, the VEINO ULTRA™ HY series improves surface finish via the creation of a glaze layer between
the casting and the mold and can even eliminate the need for a coating.

Benefits• Prevents against veining & penetration defect• Improves surface finish• Lower gas emission than organic varieties• Minimal effect on tensile strength• Potential for coating free application

Sand compaction via a fluxing agent
VEINO ULTRA™ RS Series utilizes a mineral component to aid in the compaction of silica sandduring expansion. Ultimately, the fluxing agent reduces the melt point of the sand which, in turn,allows the sand to deform into the voids.
