Paramus — Rheology & Workability Screen

Overview

Give an early read on flow and workability: relate solids loading, thickeners, and shear response to sag, leveling, and pumpability. The value is shear-profile triage, not one lookup.

Guidance vs execution: rheology and flow estimates come from tested Paramus tools. Treat outputs as screening signals, not certified application performance.

When to Use

• Checking sag, leveling, or pumpability of a coating/mortar/adhesive
• Tuning thickeners or solids loading toward an application window Do not use for: certified application qualification or bulk mechanical properties.

Workflow

Formulation + application method
  ↓ 1. Estimate low/high-shear viscosity → at rest vs application
  ↓ 2. Assess thixotropy / yield stress  → sag vs leveling
  ↓ 3. Map to application window         → spray/brush/pump/trowel
  ↓ 4. Flag defects                      → sag, poor leveling, drag
  ↓ 5. Emit workability summary          → ranked levers + provenance

Procedure

1. Discover tools via search/get_schema ("rheology", "viscosity", "flow").
2. Estimate low- and high-shear viscosity for rest vs application.
3. Assess yield stress/thixotropy governing sag vs leveling.
4. Map the shear profile onto the application method's window.
5. Flag likely defects (sag, poor leveling, roller drag).
6. Emit a ranked workability summary with provenance.

Domain Judgment

• One viscosity number is not enough — the shear profile decides behavior.
• Sag resistance and leveling pull in opposite directions; name the trade-off.
• Match the rheology target to the actual application method.

Fallbacks

• Rheology tool unavailable → deliver a manual shear-profile checklist.
• Endpoint unreachable → stop and report; do not fabricate flow curves.
