UV absorbers

UV absorbers are components of light stabilizers used in coatings to protect materials from the damaging effects of ultraviolet (UV) radiation. These absorbers are used in various applications including coatings, paints, plastics and other coatings to prevent the aging and degradation of materials by UV light.

Light stabilizers with UV absorbers work by absorbing UV radiation and releasing it in the form of heat. This prevents the UV rays from penetrating the material and destabilizing or changing it. These protective mechanisms are particularly important for extending the service life of products that are used outdoors or in environments with intense sunlight.

Coatings with UV absorbers not only offer protection against color changes and surface damage, but also help to maintain the structural integrity of materials. Plastics, paints or other surfaces exposed to UV radiation tend to weather, yellow or become brittle. UV absorbers help to minimize these undesirable effects.

In the manufacture of coatings, the selection and dosage of UV absorbers is crucial in order to achieve an effective protective effect. State-of-the-art formulations not only take UV protection into account, but also other requirements such as transparency, adhesion and chemical resistance of the coating. UV absorbers are therefore indispensable components for maintaining the performance and aesthetics of coated materials.
