Adhesion & Release

Adhesion & Release

Adhesion measures the strength required to separate an adhesive bond, ensuring the material stays secured. Release measures the force required to separate an adhesive from its liner or a non-stick surface, ensuring easy removal without damaging the substrate. Both tests are vital for product design, guaranteeing the material performs reliably in both application and removal stages.

  • Bond Strength: Measures the force needed to break the cohesive or adhesive bond of the material, critical for structural integrity.
  • Separation Force: Quantifies the low-force requirement for clean, easy removal from a release liner or protected surface.
  • Testing Geometry: Utilizes various standardized methods like 90∘ or 180∘ peel tests and shear tests to replicate real-world forces.
