At a glance for your formula

Arkema RHEOTECH 4000 LC is an acrylic associative thickener for alkaline water-based formulations. The supplier describes medium-shear rheology control, easier brush or roller handling, and improved color acceptance with limited viscosity change after tinting. It reports a reduced product footprint against standard HASE thickeners, with additional regional claims for EMEA supply. These comparisons do not establish an advantage over the starter cellulose-derived thickener.

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

Arkema / Coatex: RHEOTECH 4000 LC

Arkema / Coatex · Supplier-reported · Awaiting human review

Listed claims

  • Supplier reports >15% lower footprint versus standard HASE
  • EMEA has separate figures.

Suggested applications

  • Alkaline water-based paints
  • Brush- or roller-applied coatings
  • Tinted water-based formulations

Sustainability highlights

  • More than 15% lower product footprint versus standard HASE, according to supplier.
  • EMEA only: 29% biocarbon and 24% footprint reduction.

Performance highlights

  • Medium-shear viscosity and application control.
  • Color acceptance with reduced tinting-related viscosity/rub-out issues.

Grade scope & review questions

  • Supplier-reported information; awaiting human review. Free-of statements mean not intentionally added. RHEOTECH 4000 MB is separate.
  • Gap: Current regional SDS and claim calculation basis require confirmation.
  • Gap: Starter neutralization, dose and environmental comparison: not established.
  • No exact chemical identity/CAS supplied for this commercial grade or family; do not infer one from chemistry words or trade name.

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.
