FINAT peel adhesion

Testing the adhesive strength of adhesive labels, self-adhesive labels, adhesive tapes, silicone coatings against standard glass plate or original surfaces/adhesives

In short — AI-generated

The FINAT test methods measure the adhesive strength and release properties of self-adhesive labels, tapes, and silicone coatings. Depending on the specific method, the sample is peeled from a standardized surface or an original substrate at a defined angle and speed, or the force required to separate a silicone liner is measured.

The resulting values quantify the initial tack, permanent adhesion, or release force of the material. These metrics are used in practice to ensure that labels adhere reliably to packaging surfaces or that silicone liners can be removed with the appropriate level of force during automated processing.

Specific Norm: FTM 9

Testing of loop- tack properties

Create test order

Finat FTM 11: silicone coatings- subsequent adhesion

Specific Norm: FTM 11

Test to evaluate the influence of a release surface on the adhesive properties. The adhesive strength of a standard adhesive tape against float glass without and after contact with the release surface is compared.
