Overview

Choosing the right adhesive for your application

Selecting an adhesive—whether a technical tape or an industrial glue—cannot rely solely on a catalog. Each application presents its own constraints: substrate type, temperature, humidity, mechanical stress, and service duration.

That’s why our ADEZIF laboratory conducts a complete range of standardized and custom adhesion tests to determine the most efficient adhesive for your specific use.

	Static or dynamic shear tests – Static or dynamic shear tests measure the mechanical resistance under parallel stress (FINAT FTM 8 and FTM 18).
	Peel tests (90° or 180°) – evaluate the separation force according to FINAT FTM 2.
	Pull-off tests – determine the force required to detach the adhesive perpendicularly.
	Cleavage tests – assess lever-effect resistance (ASTM D1062, ISO 25217).
	Tack tests (ball tack, loop tack) – evaluate instant bonding strength or initial adhesion.

👉 Goal: provide reliable, actionable results to help you select the perfect adhesive solution for your specifications.

Static shear test

This test applies a fixed load to a bonded sample and measures time to failure, showing long-term performance under constant stress.

Standard	Applications	Results
FINAT FTM 8	Double-sided tapes, permanent fixations, adhesives under continuous load	Holding time before detachment, failure mode analysis

Dynamic shear test

Evaluates maximum resistance under progressive stress using a traction bench.

Standard	Applications	Results
FINAT FTM 18	Structural assemblies, high-performance glues, adhesives exposed to shocks or vibrations	Maximum force before failure, failure mode analysis

Peel test 90° or 180°

Measures the force required to remove an adhesive from a surface at a 90° or 180° angle.

Standard	Applications	Results
FINAT FTM 2	Industrial labels, technical films, mounting tapes	Adhesion force (N/cm), failure type (clean, transfer, cohesive)

Pull-off test

Determines the force required to detach a coating or adhesive from its substrate with perpendicular tension. Especially relevant for aerospace, automotive, and construction industries, where mechanical reliability is critical.

Applications	Results
Structural glues, adhesives on metals, coatings	Pull-off strength (N/mm²), rupture type

Cleavage test

Separates two bonded rigid substrates with a lever-type force, concentrating stress at the bond’s leading edge.

Standards	Applications	Results
ASTM D1062, ISO 25217	Structural adhesives, aerospace, automotive, and construction uses	Cleavage force required to initiate and propagate failure

👉 Designed to test mechanical performance under extreme stress conditions.

Tack test (instant adhesion)

Measures instant bonding ability when the adhesive contacts a substrate.

Methods	Applications	Results
Tack loop, rolling ball test	Pressure-sensitive adhesives, repositionable tapes	Tack level based on chosen standard and method

FAQ – Frequently asked questions about adhesion tests

What is the difference between a peel and a cleavage test?
Peel tests pull the adhesive strip at a constant angle (usually 90° or 180°) distributing force evenly. Cleavage tests use a lever force between rigid substrates, concentrating stress at the breaking point.
How do I know which test to choose?
It depends on the application: peel evaluates separation force, static shear tests long-term hold, and dynamic shear measures peak resistance. ADEZIF’s team can determine the best test or follow your specific testing protocol.
Can you test on different materials?
Yes, we test on stainless steel, aluminum, glass, technical plastics, and your own materials upon request.
Do you provide detailed test reports?
Yes, each test includes graphs, average values, and a quality analysis.
Do you perform aging tests?
Yes, we offer UV, humidity, and temperature exposure tests to simulate long-term durability.
