Test Method: SATRA TM426

Spotting tack - instrumental method

March 2000

SCOPE

This method is intended to assess the spotting tack at bonding of a dry adhesive film, usually after heat reactivation. The method is applicable to all types of heat reactivated or cold bonding adhesives used for footwear sole bonds. It can also be used to assess the influences of soling and upper materials on the spotting tack of an adhesive.

PRINCIPLE

Pieces of footwear soling and upper materials are coated with an adhesive. The dry adhesive film on the soling material is heat reactivated, if required, and brought into contact with the dry adhesive film on the upper material under a specified light pressure. The bond formed is immediately broken by separating the materials and the maximum separation force recorded as a measure of the spotting tack.
