1. Product Overview & Specifications

2. Key Applications

UV-928 is a high-performance benzotriazole-based ultraviolet absorber widely used in:

• Coatings: Protects automotive paints, powder coatings, and coil coatings from UV-induced degradation, yellowing, and loss of gloss.
• Polymers: Extends lifespan of polyolefins (PP, PE), PVC, and engineering plastics in outdoor applications.
• Adhesives & Inks: Prevents color fading and maintains structural integrity in UV-exposed environments.
• Specialty Chemicals: Enhances durability of synthetic fibers and rubber products.

Synergistic Effect: Combines with hindered amine light stabilizers (HALS) for superior photostability in demanding conditions.

3. Usage Guidelines

Recommended Dosage:

• Coatings: 0.5–2.0% by weight
• Plastics: 0.2–1.5% by weight

Processing Tips:

• Add during mixing phase for homogeneous dispersion.
• Avoid exposure to sulfur-containing compounds or halogenated stabilizers.
• Storage: Keep in sealed, dry, and dark conditions below 30°C.

4. Industry Case Studies

Case 1: Automotive Clear Coats

A European automotive manufacturer integrated UV-928 (0.8% wt) into polyurethane clear coats, achieving a 40% reduction in yellowing after 2,000 hours of QUV-B exposure.

Case 2: Outdoor PVC Profiles

Addition of 1.2% UV-928 to PVC window frames extended service life by 8 years under intense solar radiation, maintaining >90% impact strength retention.

5. Client Success Stories

Client A: High-Performance Powder Coatings

A leading Asian coatings producer reported 15% higher scratch resistance and zero gloss loss in architectural powder coatings after adopting UV-928, meeting ISO 16474-3 standards.

Client B: Engineering Plastics

A US-based polymer company achieved UL 746C F1 compliance in nylon components by combining UV-928 with HALS, reducing warranty claims by 22% annually.
