Function tag evidence & scope

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

At a glance for your formula

Dow ROPAQUE ULTRA-E is a hollow-sphere polymer dispersion used as an opaque pigment in water-based architectural paints. The supplier describes partial titanium-dioxide replacement and a lower carbon footprint than titanium dioxide. Its optical effect develops as the paint dries, so wet and dry hiding must be evaluated separately. Trials must rebalance pigment volume and binder demand rather than assume an equal-weight substitution.

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

Dow: ROPAQUE ULTRA-E

Dow · Supplier-reported · Awaiting human review

Listed claims

  • Supplier reports partial TiO2 replacement and lower footprint than TiO2.

Suggested applications

  • Water-based architectural paints

Sustainability highlights

  • Partial titanium-dioxide replacement opportunity.
  • Supplier lower-footprint comparison with titanium dioxide
  • no starter-paint saving quantified.

Performance highlights

  • Dry-film opacity from hollow polymer particles.
  • Supports low-VOC waterborne paint formulation.

Grade scope & review questions

  • Supplier-reported information; awaiting human review. Synthetic polymer: renewable content and biodegradability are not established.
  • Gap: Current exact-grade SDS/TDS require supplier access.
  • Gap: Dose, wet hiding and finished-paint performance require trials.
  • No exact chemical identity/CAS supplied for this commercial grade or family; do not infer one from chemistry words or trade name.

Core data coverage: 12.5%

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.
