No-Bake Binder Systems

A well-established authority in No-Bake Technology

ASK Chemicals has been a leader in developing no-bake technology throughout the years. Our legacy as no-bake innovators goes back well beyond the introduction of PEP SET in the 1970s, 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.  

PHENOLIC URETHANE NO-BAKE

PEP SET

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 turn table) PEP SET can produce fully cured molds in less than 90 seconds! Speed can be adjusted with the quality of PEP SET-Catalysts. Application flexibility and overall ease of use make PEP SET ideal in satisfying any mold making requirement. 

Benefits:

  • Predictable & repeatable cure times
  • Superior work time / strip time ratio
  • Excellent core & mold strengths
  • Ease of reclamation (mechanically, thermally)
  • Excellent shake-out and release

ACID CURING NO-BAKE

ASKURAN, CHEM-REZ, BERANOL

The product range of brands for acid curing processes includes furan- and phenolic-resins and serves for a wide range of applications in foundries. ASKURAN -, CHEM-REZ- and BERANOL -resins can be applied for all casting dimensions and metal types depending on the sand characteristic and related analytical data.

Benefits:

  • Excellent casting surface
  • Controllable curing speed
  • High strength
  • Excellent shake-out and release
  • Ease of reclamation (mechanically) 

ASKURAN RS NO-BAKE

ASKURAN RS is a furan resin binder for the no-bake acid hardening process with reduced sulfur content. The binder system offers environmental benefits as well as a solution for improving casting quality and productivity. The special chemical properties of the ASKURAN RS binders help to optimize the casting processes in foundries.

Benefits:

  • Reduction in sulfur dioxide emissions
  • Lower sulfur content in the mechanically reclaimed sand
  • Lower environmental pollution and emission of disagreeable odors
  • Minimum graphite degradation during nodular casting
  • Increased casting productivity

ESTER CURING NO-BAKE

ALPHASET & NOVASET

The no-bake solution for all metals, especially steel castings, and all mould sizes. This ester-curing water-based no-bake binder is capable of being used in most casting processes. It's water-based nature reduces material handling requirements, as well as casting defects associated with solvent based binder systems.  Part II of this no-bake binder requires a liquid ester co-reactant. ASK Chemicals offers the widest range of co-reactants allowing for all levels of productivity. Thus, ALPHASET & Novaset are ideal in most large scale casting productions, especially in steel applications. It should be noted that as with all Alkaline Phenolic No-Bake technology sand reclamation is more problematic requiring greater control than other no-bake processes. ASK Chemicals fortunately offers industry leading technical services to assist you in all your casting challenges.

Benefits:

  • Excellent casting surface
  • Wide variety of co-reactants 
  • Eco-friendly organic binder system
  • Ideal for use in steel casting production

ALPHASET is commercialized in Europe by ASK Chemicals.
