Screen a pigment dispersion for flocculation, settling, and color-drift risk by evaluating dispersant fit, particle-surface chemistry, and rheology with Paramus property and compatibility tools.When to use: a user needs an early read on whether a pigment dispersion will stay stable and color-true.Multi-tool WORKFLOW with colloidal-stability judgment.
Paramus — Pigment Dispersion Stability Screen
Overview
Give an early read on pigment dispersion stability: flag flocculation, settling, and color drift, and check dispersant fit. The value is triage across pigment/dispersant/medium, not one lookup.
Guidance vs execution: dispersant-fit and stability estimates come from tested Paramus tools. Treat outputs as screening signals, not certified shelf stability.
When to Use
- Selecting or checking a dispersant for a pigment/medium pair
- Diagnosing settling, flooding/floating, or color drift risk early Do not use for: final color-matching (use color tools) or certified storage-stability claims.
Workflow
Pigment + dispersant + medium
↓ 1. Characterize pigment surface → polarity / charge
↓ 2. Check dispersant fit → anchor + steric/electrostatic
↓ 3. Predict colloidal stability → flocculation/settling risk
↓ 4. Flag color-drift pathways → flooding/floating
↓ 5. Emit stability summary → ranked risks + mitigations
Procedure
- Discover tools via
search/get_schema("dispersion", "stability", "surface"). - Characterize the pigment surface chemistry and polarity.
- Assess dispersant anchoring and stabilization mechanism fit.
- Predict flocculation/settling propensity in the medium.
- Flag color-drift pathways (flooding/floating) and mitigations.
- Emit a ranked stability summary with provenance.
Domain Judgment
- Stability is system-specific — the same dispersant can fail in a different medium.
- Consider both steric and electrostatic contributions, not one in isolation.
- Rank by likelihood × visual impact so the user knows what to test first.
Fallbacks
- Surface/stability tool unavailable → deliver a manual dispersant-selection checklist.
- Endpoint unreachable → stop and report; do not fabricate stability verdicts.
