Solvent-based Adhesives
Solvent-based adhesives principally consist of polymers such as
natural rubber, polychloroprene,
etc., dissolved in aliphatic or aromatic solvents.
Natural and chloroprene rubbers are unsaturated elastomers and are therefore susceptible
to attack by oxygen and light. Although they are not exposed to very high temperatures
during processing, as is the case in the preparation of hot melt adhesives, they
do need to be stabilized against degradation in end use, especially when used in
thin films.
Therefore, stabilizers should be added in the formulation to protect the adhesive
during both processing (drying) and service life. There are products in market which
are effective antioxidants for such applications:
