UV Absorber 400 Chemical Properties, Uses & Applications | Ecochem China
Description
UV Absorber 400 is a liquid hydroxyphenyl-triazine (HPT) UV absorber engineered to meet the high-performance and durability requirements of waterborne, solventborne, and 100% solids automotive and industrial coatings. With its low color profile and excellent stability, it is especially suitable for applications where color transparency is critical—making it ideal for use in advanced UV-curable clear coats alongside the latest generation photoinitiators.
Key Benefits
Exceptional UV protection and long-term performance
Highly stable under extreme thermal conditions and high-bake cycles
Hydroxy functionality ensures minimal migration
High photostability for extended service life
High concentration allows for efficient performance at lower dosages
Chemical Properties
Appearance: Yellow viscous liquid
Chemical Type: Hydroxyphenyl-triazine (HPT)
Performance Characteristics
UV Absorber 400 offers superior thermal and light stability, making it highly effective in coatings exposed to severe environmental conditions. Its hydroxy functionality reduces migration, while its high UV absorption capacity ensures strong photostability. Designed for coatings that require long-term clarity and protection, UV-400 is particularly well-suited for both OEM and refinish automotive systems.
Applications
UV-400 is recommended for:
Solventborne and waterborne automotive OEM coatings
Refinish coating systems
UV-cured coatings
Industrial finishes requiring long-lasting protection
Synergistic Use with HALS
For enhanced UV protection and coating durability, UV-400 can be used in combination with Hindered Amine Light Stabilizers (HALS) such as LS-123 or LS-292. These combinations help prevent gloss loss, cracking, blistering, and delamination in clear coats exposed to outdoor environments.
Recommended Dosage
(Based on weight percent of binder solids):
UV-400: 1.0 – 3.0%
HALS (e.g., LS-123 or LS-292): 0.5 – 2.0%

The Role of UV Absorbers
UV Absorbers are essential additives used in plastics, coatings, adhesives, and films to protect materials from the damaging effects of ultraviolet (UV) radiation. They function by absorbing harmful UV light and converting it into harmless heat, preventing photo-degradation.
UV Protection: They prevent yellowing, fading, brittleness, and loss of mechanical strength by blocking UV radiation before it affects the polymer.
Color Retention: Ideal for clear or colored applications, UV absorbers preserve the original appearance of plastics and coatings exposed to sunlight.
Additive Protection: UV absorbers also safeguard other sensitive additives like pigments, antioxidants, and flame retardants from UV damage.
Complementary Use: When used alongside HALS (Hindered Amine Light Stabilizers), they offer synergistic protection, combining surface and deep-layer stabilization.
