MAGNASETTM 2.0

THE NEW GENERATION OF
ENVIRONMENTALLY FRIENDLY FURANRESINS WITH IMPROVED CLASSIFICATION
The modern foundry industry is characterized by highquality requirements and strict environmental regulations
defining emission thresholds. At the same time, theimportance of sustainability aspects and health awareness are becoming more and more important.
In this context, ASK Chemicals has developed
MAGNASET TM as new generation of furan resins without
the skull and crossbones labeling, with reduced freefurfuryl alcohol content, yet with performance comparable
to conventional furan resins. This second generation ofMAGNASETTM resins have improved storage stability andexcellent reactivity characteristics.

Sand mixture: mechanical reclaimed silica sand (AFS 43; pH approx. 3, loss on ignition approx. 2 %); 0.9% resin /0.3 % hardener (65 % PTSA); sand temp. 20°C/ room temp. 20°C / rel. humidity 40 %MAGNASETTM-technology has been developed as a newgeneration of low-formaldehyde furan no-bake binders(FNB) with a milder classification requiring no skull andcrossbones labeling. The casting performance of the newMAGNASETTM resins is comparable to „state-of-the-art“
furan resins (free FA: 50-95 %), although they have asignificantly lower free FA content (<40 %). This leads toa significant reduction in furfuryl alcohol emissions during
mixing and molding.
MAGNASETTM-resins can be cured with acidic hardener
GS II, for example, and the reactivity can be easily adjusted
by selecting the appropriate type and quantity of hardener.
The intrinsic high reactivity of those resins makes it possible
to use less reactive catalysts with reduced sulfur content,
which ASK Chemicals offer as the “RS” hardener series. In
combination with the low free FA content, the “RS” series
has the potential to further decrease overall emissions. Thereduced sulfur content has a positive effect on the quality ofthe castings as well.
The portfolio encompasses a series of resins with tailoredproperties suitable for all types of casting and customer
needs, providing good molding properties and excellent
casting surfaces. MAGNASETTM 5912 LFA is a phenol-freeresin with a very low free formaldehyde content (<0.1 %)and a medium to high reactivity, which makes it an“allrounder” for all types of castings. As a mixed resin,MAGNASETTM 204 ES LFA offers both low free phenol(< 1.0 %) and free formaldehyde contents (<0.1 %) withperformance comparable to phenol-free MAGNASETTM
systems.
The reduced FA content as well as the high reactivity of theresin cause a slightly lower storage stability as compared tostandard FNB resins, but the stability is still superior to thatof phenolic resins.
The newly developed resins show the desired improved
storage stability as well as comparable reactivity to thefirst MAGNASETTM generation. The viscosity values forMAGNASETTM 2.0 remain at a constantly low level. Highreactivity as well as excellent strength development wasalso achieved, comparable to conventional furan resins
and MAGNASETTM Gen 1 resins.
