Antioxidants for Adhesives

Adhesives and their raw materials react like other organic materials with oxygen in a process called autoxidation. This guide offers you an extended overview of Antioxidants in the adhesives & sealant industry. You will be able to select the antioxidant you need from the different antioxidant families mentioned here. This guide will also take a look into antioxidant benefits and applications. You can also check how to test and determine the efficiency of the antioxidant(s) you have selected.

Polychloroprene

Polychloroprene is one of the most versatile materials used as a base for elastomeric adhesives. Contact adhesives made of chloroprene films develop high bond strength, high tack level, and auto-adhesion.

To determine the appropriate antioxidant and antioxidant level to use, it is necessary to conduct testing based on the application requirements. Non-staining, non-discoloring antioxidants are recommended. They offer overall good stabilizer performance.
