Binder Systems


High-performance advantages for the highest requirements

The cold box process is a high-performance, highly productive core manufacturing method that is used in large series production of cast parts in particular and features high process reliability and productivity. The defining feature of the cold box process is its high reactivity, which makes short production cycles possible for core production. ASK Chemicals has not only succeeded in further developing the process in terms of productivity but also with regard to humans and the environment. Our cold box systems offer you the following advantages:

  • The advantages for the environment and your staff
  • Reduced odor in core production and casting.
  • Low emissions of BTX gases.
  • Low monomer content.
  • Low-odor, nonhazardous solvents.
  • The advantage of increased productivity
  • Faster cycle times thanks to high reactivity.
  • Higher tool availability thanks to lower contamination from condensate and a lower tendency for adhesion.
  • Time saving since cleaning the core box requires less work.
  • Long sand bench life thanks to high strength.
  • The advantage of increased quality
  • Fewer casting defects thanks to process-optimized binders.
  • High dimensional consistency of the core during production and while the coating is drying thanks to high strength.
  • High dimensional consistency during casting thanks to high deformation stability.
  • High core quality and stability thanks to high process reliability and high strengths.
  • The advantage of cost reduction
  • Reduced binder consumption thanks to higher efficiency
  • High tool availability thanks to lower contamination from condensate and a lower tendency for adhesion Fewer cores are rejected thanks to higher stability
  • Reduced catalyst consumption thanks to high reactivity


ASK Chemicals is a leader in developing no-bake technology. Our legacy as no-bake innovators goes back well beyond the introduction of PEP SET™ in the 1970’s the industry revolutionizing phenolic urethane no-bake binder system. In fact, the very history of no-bake binder technology can be traced, in large part, to our researchers. This all stands as proof to our exceptional competence & expertise on the subject of all no-bake technologies presently available on the market.  


PEP SET is arguably the most trusted name in the no-bake marketplace. Known for its exceptional quality & highly controllable curing reactions, PEP SET has long been the standard in no-bake excellence. In fact, when placed on an automated production line (roller-loop or turntable) PEP SET can produce molds ready to be stripped in less than 90 seconds! Clearly, speed, application flexibility and overall ease of use make PEP SET ideal in satisfying any mold making requirement. PEP SET resins are available in several variations for performance, long work/strip times, smoke, odor and other environmental benefits some of these varieties are: PEP SET QUANTUM, PEP SET MAGNA, and PEP SET PATRIOT.
Predictable & repeatable cure times Superior work time / strip time ratio Excellent core & mold strengths Ease of reclamation

FURAN No-Bake and Warm Box Resins (CHEM-REZ™)

ASK Chemicals offers a wide range of furan no-bake and warm box resins. CHEM-REZ binders can be applied for all casting dimensions and metal types. A wide catalyst range can help tailor cure speeds to optimize your process. CHEM-REZ binders are available under the trade names: CHEM-REZ FURY, CHEM-REZ FLEXSET, and CHEM-REZ DURASET. Each of these sub-sets of the CHEM-REZ product lines has resins with specific benefits for individual foundry needs.
Excellent casting surface finish Controllable curing speed High strength Excellent shake-out and release Excellent reclaimability  


This ester-curing water-based no-bake resin system is capable of being used in most casting processes. Its water-based nature reduces material handling requirements, as well as casting defects associated with solvent based binder systems. This no-bake binder requires a liquid ester co-reactant to cure the resin. ASK Chemicals offers a wide range of co-reactants allowing for all levels of productivity. NOVASET ideal in most large scale casting productions, especially in steel applications. Sand coated with NOVASET HK+ RESIN can be thermally reclaimed with the use of NOVATHERM™ RSA 40 as part of the reclamation process.
Wide variety of co-reactants Eco-friendly organic binder system Ideal for use in steel casting production  


ACCOSET no-bake binders are water-based solutions of sodium silicate that can be hardened on sand by curing with an organic ester catalyst. The ACCOSET no-bake sodium silicate binders are all-purpose binders used to produce a variety of molds and exterior cores which require high strengths for handling purposes.
Several types available depending on strength and shakeout needs Low smoke and odor A wide range of catalysts to determine work time/strip time  

Alkyd-Oil (LINO-CURE™)

LINO-CURE is an alkyd-oil three part binder system that works well for large cores and molds. It has a long available work time and strip time with excellent stripping characteristics. It works well with high pH sands such as olivine sand.
Works well with all metal types Excellent stripping characteristics for worn or complicated patterns
