Ultraviolet absorbent, also known as UV absorber, is the most widely used light stabilizer, which can absorb the ultraviolet from the sunlight and fluorescent light source without changes to itself. It can be used for plastics, coatings, dyes, automotive windshields, cosmetics, pharmaceuticals, sunscreen and so on.
What functions does ultraviolet absorbent have?
can usually protect products like paints, plastics from degradation caused by
the ultraviolet ray irradiation, and thus to extend the service life of these
products. As we know, ultraviolet light can oxidize the plastics and other
polymers and damage the appearance and mechanical functions of these products. Ultraviolet
absorbent is an effective way is to prevent the harmful ultraviolet light.
How many types of UV absorbers are there?
different types of ultraviolet absorbents which can absorb ultraviolet of
various wavelengths, and can be applicable in different types of polymers. UV
absorbers can be divided into the following categories by chemical structures:
salicylic acid esters, benzophenones, benzotriazoles, substituted
acrylonitrile, triazine and other categories.
What are the common features of the ultraviolet
Most of the
ultraviolet absorbents have the following features: strong ultraviolet
absorption abilities, good thermal stability(do not change or volatilize under heat), good chemical stability (no
adverse reaction with the material components in the product), good
compatibility, good photochemical stability (do not decompose or change color),
colorless, non-toxic, and odorless, insoluble in water; cheap, easy to get.
Ultraviolet absorbents used in coatings
absorbents used in coatings or paints have good compatibility and have
anti-oxidization, anti-yellowing properties, and can be very safe to be used
with other antioxidants products. They can effectively protect the coating
luster, avoid cracking and spots. With different properties, the ultraviolet
absorbents can be used in various coating systems, like water based coatings, wood
coatings, industrial coatings, automotive coatings, etc.
Where to buy the ultraviolet absorbents?
ultraviolet absorbents are commonly seen and are very easy to get. On OKCHEM,
you can purchase different types of the UV absorbers at one stop. JiangsuJuming Chemical Technology Co.,Ltd, is one of the renowned ultraviolet
