Product Description

Product Description

UV Absorber 400 CAS 153519-44-9

UV Absorber 400 is a chemical additive designed to protect materials from ultraviolet (UV) radiation, particularly in the UVA range (315-400 nm). Here's a structured overview:1. Function:* Absorbs UV radiation, converting it into heat to prevent degradation of materials like plastics, coatings, and cosmetics.* Targets wavelengths up to 400 nm, offering protection against the full UVA spectrum.2. Chemical Composition:* Likely belongs to a class of organic UV absorbers such as benzotriazoles, triazines (e.g., bis-resorcinyl triazine derivatives), or benzophenones.3. Applications:* Used in polymers (e.g., polyolefins, PVC) to prevent yellowing and structural breakdown.* Potentially employed in coatings, adhesives, or sunscreens for enhanced UV stability.4. Key Features:* High efficacy in the UVA range, critical for preventing long-term UV damage.* May offer compatibility with various matrices and thermal stability for processing.

Applicaiton

UV absorber UV-400 is designed for industrial and automotive paints with high performance and durability requirements. It is recommended for:


Solvent and water-based automotive coatings

Ammonium or metal-catalyzed automotive OEM coatings and repair paint coating systems

UV-curing coatings

Industrial coatings

If UV absorber UV 400 is used in combination with hindered amine light stabilizers, such as light stabilizer LS-292 or light stabilizer LS-123, its performance can be significantly improved. This synergistic effect has a good inhibitory effect on the reduction of gloss, cracking, blistering, delamination and discoloration of varnish.
