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.

Butyl Rubbers

Butyl rubber is a copolymer of isobutylene and isoprene. It has excellent air retention, energy absorption and water resistance. These unique properties make it very suitable as a base for sealants and sealing tapes. Most butyl compositions are one component and many are used in industrial and construction applications.

Typical butyl sealants, as well as sealing tapes compositions, incorporate a phenolic type antioxidant to prevent the thermal oxidation of the butyl rubber by chain scission. Stabilizer blends are also recommended.
