Screen an adhesive formulation for expected bond strength by relating polymer backbone, tackifier, and crosslink density to cohesive and adhesive failure modes with Paramus property-prediction tools.When to use: a user needs an early read on whether an adhesive formulation will meet a bond-strength target.Multi-tool WORKFLOW with failure-mode judgment.
Paramus — Adhesive Bond Strength Screen
Overview
Give an early read on adhesive bond strength: relate backbone, tackifier, and crosslink density to cohesive vs adhesive failure. The value is triage across formulation levers, not one lookup.
Guidance vs execution: mechanical and cohesion estimates come from tested Paramus tools. Treat outputs as screening signals, not certified joint performance.
When to Use
- Early bond-strength risk read for a candidate adhesive
- Deciding which formulation levers to pull toward a strength target Do not use for: certified joint qualification or substrate-specific adhesion (use adhesion screen).
Workflow
Adhesive composition + target
↓ 1. Map backbone → cohesive strength → modulus / entanglement
↓ 2. Assess tackifier / wetting → contact + green tack
↓ 3. Estimate crosslink effect → cohesion vs brittleness
↓ 4. Predict likely failure mode → cohesive / adhesive
↓ 5. Emit strength summary → ranked levers + provenance
Procedure
- Discover tools via
search/get_schema("mechanical", "adhesion", "polymer"). - Relate the polymer backbone to cohesive strength.
- Assess tackifier and wetting contributions to contact.
- Estimate the crosslink-density trade-off (cohesion vs brittleness).
- Predict the likely failure mode and its driver.
- Emit a ranked strength summary with provenance.
Domain Judgment
- Bond strength is a system property — backbone, tack, and cure interact.
- Distinguish cohesive from adhesive failure: they need different fixes.
- More crosslinking is not always stronger — brittleness can dominate.
Fallbacks
- Mechanical tool unavailable → deliver a manual failure-mode checklist.
- Endpoint unreachable → stop and report; do not fabricate strength values.
