Function tag evidence & scope

Function tags help find candidates. They do not establish suitability for water-based paint or an EcoSafe rating.

Defoamer / deaerator · Defoamer

Supplier-grade/general function only; this does not establish compatibility with a starter formula, lower hazard, an EcoSafe rating or a verified environmental improvement. Function reference ↗

At a glance for your formula

TEGO Foamex 8820 and 8850 are related organic-polymer defoamers developed as alternatives to siloxane-based products. Evonik describes different incorporation and compatibility profiles for the two grades. Detailed comparative evidence concerns printing inks and varnishes; an architectural-coatings portfolio also lists 8820. Paint use therefore needs exact-grade selection and testing rather than assuming both grades are interchangeable.

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

Evonik: TEGO Foamex 8820 / 8850 (one family candidate)

Evonik · Supplier-reported · Awaiting human review

Listed claims

  • Renewable organic-polymer route
  • strongest siloxane comparison is in inks/varnishes.

Suggested applications

  • Waterborne printing inks, 8820/8850
  • Waterborne varnishes, 8820/8850
  • Architectural coatings, 8820 portfolio evidence

Sustainability highlights

  • Supplier reports over 50% renewable content for 8820 and over 95% for 8850.
  • Organic-polymer route is described as solvent-, mineral-oil- and silicone-free.

Performance highlights

  • 8820 is positioned for higher-shear grind incorporation.
  • 8850 targets compatible let-down or post-addition use.

Grade scope & review questions

  • Architectural-paint evidence is grade-specific. Inks/varnishes comparison does not establish equivalent performance in the PCC wall paint.
  • Gap: Current grade-specific regional SDS and architectural formulation trial are needed.
  • No exact chemical identity/CAS supplied for this commercial grade or family; do not infer one from chemistry words or trade name.
  • Workbook deliberately groups related grades; preserve one candidate/family card and separate grade-specific claims.
  • Related supplier grades are grouped for navigation. Claims and application evidence retain the selected-grade scope stated in the summary; do not transfer them to every related grade.

2 of 16 defined fields are recorded with a source. This measures structured information currently on this site, not the completeness of every linked PDF. Missing fields remain in the denominator.

Coverage is separate from scientific accuracy, human verification and EcoSafe assessment. Molecular fields may not apply to a grade or family; they are not filled from another material to increase its score.

Chemical identity & commercial names

Exact identity and mixture scope require the supplier record.

Trade names & supplier grades

Trade names identify supplier offerings. A shared chemical name does not establish interchangeable grades or specifications.

  • TEGO Foamex 8820 ↗ · Evonik

    Higher-shear grind grade; architectural-paint portfolio evidence is specific to 8820.

  • TEGO Foamex 8850 ↗ · Evonik

    Compatible let-down/post-addition grade; comparison evidence concerns inks/varnishes.
