ZHTest Method: SATRA TM414
Preparation of hot melt bonded assemblies for peel tests
August 2021
SCOPE
This method is intended to describe the preparation and bonding, with hot melt adhesives, of test specimen assemblies for use in peel tests. The method is applicable to all types of material, provided at least one of the adherends is flexible.
PRINCIPLE
Method 1 - Pre-coated materials (for example linings, toe puffs and stiffeners)
A rectangular piece of the hot melt adhesive coated material is placed in contact with a similarly sized piece of standard upper material. The assembly is pressed in a heated press to activate the adhesive and form a bond. The bonded assembly is stored in a standard controlled environment for 24 hours before it is ready to be peeled.
Method 2 - Direct bonding (for example lasting)
A ribbon of molten adhesive is applied to a rectangular specimen of insole material. A similarly sized piece of a standard upper material is then placed on top of the molten adhesive and the assembly is passed immediately through a roller press to form the bond and squeeze out any excess adhesive. The bonded assembly is stored in a standard controlled environment for 24 hours and the excess hardened adhesive is then removed from the edges with a sharp knife.
The prepared specimens are then taken forward to a peel method such as SATRA TM401 in order to test their adhesion strength.
