Paramus — Substrate Adhesion Compatibility Screen

Overview

Screen adhesive/coating–substrate pairs for wetting and adhesion risk: compare surface energies and polarity, and flag primer/treatment needs. The value is cross-substrate triage, not one lookup.

Guidance vs execution: surface-energy and wetting estimates come from tested Paramus tools. Treat outputs as screening signals, not certified adhesion.

When to Use

• Checking whether a formulation will wet and adhere to a substrate
• Comparing adhesion risk across several candidate substrates Do not use for: certified peel/lap-shear qualification or bulk cohesive strength (use bond-strength screen).

Workflow

Adhesive/coating + substrate set
  ↓ 1. Estimate surface energies        → adhesive + each substrate
  ↓ 2. Compare polarity / wetting       → spreading coefficient
  ↓ 3. Flag low-energy substrates       → PP/PE/PTFE risk
  ↓ 4. Suggest primers / treatments     → corona/flame/primer
  ↓ 5. Emit adhesion summary            → ranked pairs + provenance

Procedure

1. Discover tools via search/get_schema ("surface", "wetting", "adhesion").
2. Estimate surface energies of the adhesive and each substrate.
3. Compare polarity and spreading to judge wetting.
4. Flag low-surface-energy substrates that resist adhesion.
5. Suggest surface treatments or primers where needed.
6. Emit a ranked adhesion summary with provenance.

Domain Judgment

• Wetting is necessary but not sufficient — good spreading can still fail cohesively.
• Low-energy plastics (PP/PE/PTFE) almost always need treatment; say so.
• Rank pairs by wetting margin so the user knows which need primers.

Fallbacks

• Surface tool unavailable → deliver a manual surface-energy comparison table.
• Endpoint unreachable → stop and report; do not fabricate adhesion verdicts.
