Leather Test for Adhesion of finish (Coating)
This tensile testing equipment is a universal testing machine for measuring the adhesion of the finish coat on the leather or the adhesion between two adjacent finishes. The tester is applicable to all finished leather with a smooth surface.
Test Principle
The solvent-free adhesive is used to bond part of the leather coating layer to the adhesive plate, and the force is applied to the free end of the strip leather to make the leather coating layer peel off to the specified length. The coating layer is stuck to the adhesive plate, and the force applied is the adhesion fastness of the coating layer to the leather.
Test Standards
ISO 11644, GB/T 4689
