At a glance for your formula

TEGO Foamex 812 eCO is a polyether-siloxane defoamer concentrate using mass-balanced raw materials. Evonik describes the same familiar performance as conventional Foamex 812 with reduced carbon emissions. It targets grinding-stage foam control in clear and pigmented formulations, normally alongside a more compatible let-down defoamer. The named-counterpart claim does not identify it as the unnamed defoamer in the PCC starter.

Grade-specific screening values have not been recorded. Consult the selected supplier’s technical reference.

Evonik: TEGO Foamex 812 eCO

Evonik · Supplier-reported · Awaiting human review

Listed claims

  • Mass-balanced counterpart to Foamex 812
  • allocated renewable feedstock.

Suggested applications

  • Clear aqueous coating formulations
  • Pigmented aqueous coating formulations
  • Coating grind-stage foam control

Sustainability highlights

  • Over 60% renewable mass-balance content is supplier-reported.
  • Supplier claims reduced carbon emissions versus conventional Foamex 812.

Performance highlights

  • Efficient against microfoam and macrofoam.
  • Positioned for grinding with compatible let-down defoamers.

Grade scope & review questions

  • Mass-balance allocation is distinct from measured physical biobased carbon. The exact conventional counterpart is Foamex 812.
  • Gap: Review current regional SDS and long-term formula compatibility.
  • No exact chemical identity/CAS supplied for this commercial grade or family; do not infer one from chemistry words or trade name.
