UV Absorber 328, also known as
Tinuvin 328
or
Omnistab 328
,
is
a high-efficiency ultraviolet light absorber that protects polymers and other organic substrates from UV degradation
.
It effectively absorbs UV light in the 270-340 nm range, a wavelength that can cause damage to materials.
Key Features and Applications:
-
Protection:UV Absorber 328 shields materials from UV radiation, preventing fading, cracking, yellowing, and other degradation caused by sunlight.
-
Broad Use:It's used in various applications including coatings, plastics, and other organic substrates.
-
Compatibility:It exhibits good compatibility with many resins and polymers.
-
Specific Applications:
-
Coatings:
It's particularly effective in ambient and low-temperature cured coating systems, such as alkyd-based paints.
-
Plastics:
It's used in polyolefins (especially polyethylene), polyesters, styrenic polymers, polyurethanes, and other plastics.
-
Other Applications:
It's also used in automotive coatings, industrial coatings, commercial inks, and food packaging.
-
Coatings:
It's particularly effective in ambient and low-temperature cured coating systems, such as alkyd-based paints.
Mechanism:
UV absorbers work by absorbing UV light and converting it into harmless heat.
They are often used in combination with other light stabilizers like
HALS
(Hindered Amine Light Stabilizers) for more effective protection.
Important Notes:
-
Not a UV Blocker:
UV absorbers absorb UV light, but they do not block it.
-
Alternatives:
There are other UV absorbers available, including phenolic benzotriazoles, benzophenones, HALS, and oxalanilides.
In essence, UV Absorber 328 is a vital component in protecting materials from the damaging effects of UV radiation, making it a widely used additive in various industries.
