ZHTest Method: SATRA TM402E
Preparation of polyurethane reaction moulded-on bonded test assemblies for adhesion tests
December 2016
SCOPE
This method is intended to describe the preparation and bonding, with solvent based and water based adhesives, of polyurethane reaction moulded-on test specimen assemblies for use in peel tests and heat resistance (creep) tests. The method is applicable to all types of upper material, provided at least one of the adherends is flexible.
PRINCIPLE
Standard procedures are used to prepare polyurethane reaction moulded-on bonded test assemblies using techniques as close as possible to those used in shoe manufacture, particularly for sole attaching. The method is applicable to moulded-on test assemblies for the peel test, SATRA TM401, and the heat resistance test, SATRA TM403. The procedure described in this section simulates the method most commonly used in the shoe factory for the production of footwear with reaction moulded-on polyurethane solings. A premixed polyurethane compound is poured or injected into a heated mould containing the upper material test specimens. The mould is then kept closed until the reaction is completed and the cured soling has bonded to the upper material.
