Test Method: SATRA TM422

Immediate (“green”) peel strength of adhesive bonds

December 1994

SCOPE

This method is intended to determine the peel strength of an adhesive joint immediately after it has been made. The method is mainly applicable to bonds between footwear upper and soling materials, but can be used with all types of bonded joint where at least one of the adherends is flexible.

PRINCIPLE

A bonded assembly is produced, typically using the procedure described in:

SATRA TM402 – Solvent borne or water borne adhesives.

SATRA TM414 – Hot melt adhesives (Method 1).

The assembly is then immediately peeled apart using a tensile testing machine and the average peeling force is measured a set time after producing the bond.
