To produce such solutions, the work of our R&D
department is vital. This can be described as theinterplay of innovation-driven research and customer-driven development. Today’s foundries
need to satisfy increasingly complex requirements– reduced emissions, consistent high-quality
casting, and the ability to cope with the costpressure that many foundries are facing are justsome of the instances here. Such requirements
necessitate more than just strong partnerships andoutstanding technologies: rather, first-class research and development that focuses on developing efficient, environmentally friendly solutions.

MAGNASET
Innovative generation of furan resins
MAGNASET are furan resins with a low furfuryl alcohol content that are characterized by their goodmolding and casting properties. They represent a new generation of binders whose performance iscomparable with that of standard furan resins. The lower monomeric furfuryl alcohol content in
MAGNASET resins can reduce furfuryl alcohol emission at the workplace by up to 60 %.

Benefits• Reduced VOC• No system conversion necessary, comparable• Good molding properties and excellent castingsurfaces• 60% less furfuryl emissions at the workplace

ASKURAN and CHEM-REZ
Multifaceted No-Bake binders for large castings
ASKURAN and BERANOL are binders designed for acid curing. Curing speed can be controlled by thedosage and quality of the hardener to almost any extent. The strengths achieved are very high and permit
minimal amounts of binder to be added. They guarantee a good casting surface. Depending on theindividual requirement, ASK Chemicals provides furan (FNB), phenol (PNB) or furan-phenol binder systems.

Benefits• Ease of use• Variable / adjustable cure rates• Good flowability• Ease of reclamation and shakeout• Good through-cureSulphur-reduced and highly productive
ASKURAN RS, a reduced-sulfur system, leads to a reduction of sulfur in the mold material andof sulfur dioxide emissions during the casting process. The air quality inside the foundry
and the working conditions in the foundry are improved significantly. ASKURAN RS also
provides a first-class casting surface.

3 PartPUNBPEP SETA productive and flexible No-Bake system
Known for its exceptional quality and almost fully controllable curing reactions, PEP SET has long been
the standard in No-Bake excellence. When used in an automated production line (roller-loop or turntable) PEP SET can produce fully cured molds in less than 90 seconds! Clearly, speed, application
flexibility and overall ease of use make PEP SET ideal for satisfying any core and mold-making requirement.

Benefits• Controllable cure times• Superior work time / strip time ratio• Excellent core and mold strengths• Ease of reclamation

Unrivalled emission reduction
The PU No-Bake System PEP SET Quantum is characterized by low smoke and odors
during pouring, cooling, shake out and mixing.
The new PU-No-Bake-Binder PEP SET Silver additionally leads to a strong reduction of thephenol emissions as well as to a reduction of phenol concentrations in reclaimed sands. WithPEP SET Silver, ASK Chemicals is setting new standards in reducing emissions in PU no-bakefoundries.

ALPHASETThe No-Bake solution for steel castings
This two-part binder system composed of a water-based resole resin cured with a liquid ester co-reactant
can be used in most casting processes. ASK Chemicals offers a wide range of co-reactants, allowing forvarying levels of productivity. ALPHASET is ideal in most large-scale casting production, especially insteel applications. Due to the alkaline properties of this technology, we recommend the use of ALPHASET
additives for the reclaim of sands. This considerably increases the quality of the reclaimed sand.

Benefits• Ease of use• Low odor during core and mold-making• Supression of casting defects• Excellent casting surface quality, especially insteel

Reclamation recommendation – ALPHASET RSAASK Chemicals recommends using ALPHASET RSA reclaim sand additive with all
ALPHASET applications. This unique additive maximizes the removal of residual binder
to increase reclaimed sand yields. ALPHASET RSA enables the use of a higher percentageof reclaimed sand during mold-making, which results in a lower cost per ton of sand.
