Light Stabilizers / UV Absorbers

Adhesives if exposed to sunlight/UV rays can undergo several irreversible changes like discoloration and loss of adhesion. As a result, the service life and aesthetics of the adhesive/sealant get decreased. To retard the deterioration caused by sunlight and other UV light sources, formulators add UV absorbers/light stabilizers to adhesives and sealants. There are various UV absorbers/ light stabilizers available as additives but the most commonly used are hindered amine light stabilizers (HALS), benzotriazoles and benzophenones.

UV/Light Stabilizers for Adhesives

When adhesives and sealants are used in outdoor environments, the action of light can lead to detrimental effects on both appearance and performance. UV degradation usually manifests itself by either or both discoloration and a reduction in joint strength and general physical properties. The effect of UV radiation on a joint is not only due to changes in the adhesive or sealant, but changes in the substrate could also occur due to UV exposure. Although UV resistance is often a minor concern in the selection or formulation of an adhesive or sealant, it can be extremely important in certain systems and...
