Adhesives have become part of everyday life, and are
used in a wide range of applications. The increasingly demanding requirements
to which modern adhesives are expected to meet can only be achieved and
retained by using appropriate stabilizer systems.
Adhesives and their raw materials react like other organic
materials with oxygen in a process called "autoxidation." Autoxidation
is initiated by heat, light, mechanical stress, catalyst residues, or
reaction with impurities. Adhesive
degradation results in discoloration, viscosity changes, char formation,
cracking and loss of adhesion. Antioxidants interrupt the degradation
process in different ways, according to their structure.
In this Antioxidants Center we offer you an extended
overview of Antioxidants in the adhesives & sealant industry. The
following topics are discussed:
