OMNISTAB UV571 – Versatile UV Absorber for Aging and Yellowing Protection

2026.10.22

In plastics, coatings, synthetic fibers, and polyurethane materials, UV exposure causes aging, gloss loss, cracking, and yellowing—key factors affecting product lifespan and appearance. OMNISTAB UV571 offers broad-spectrum UV absorption, blocking UV-induced photo-oxidative degradation at the source and protecting both the appearance and performance of substrates.




Core Advantages

  1. Excellent compatibility with multiple substrates
    Compatible with PVC, PVB, PMMA, EVA, EVOH, PA, PET, PP, PUR, and more. No migration, precipitation, or blooming during long-term use. Maintains transparency, color, and mechanical properties—ideal for high-clarity products.

  2. High heat resistance & low volatility
    Excellent thermal stability and very low volatility, suitable for high-temperature processing such as plastic modification, spinning, and high-temperature curing coatings.

  3. Compatible with oil-based and water-based systems
    Dissolves evenly in solvent systems and disperses quickly in water-based adhesives and coatings. Works in solvent-based, water-based, and solvent-free systems.



Main Applications

  • Polyurethane systems – A core application area: TPU coatings, PU foams, and underwear cotton. Provides effective light stabilization, resists aging from light and humidity, improves anti-yellowing performance, and extends product lifespan.

  • Plastic & rubber modification – Weathering modification for rigid and plasticized PVC, PVB, PMMA, PVDC, EVOH, EVA, etc.

  • Coatings & adhesives – Suitable for low-solvent or solvent-free automotive coatings, industrial coatings, wood coatings, and various adhesive systems.

  • Synthetic fibers & textiles – Used as a spinning additive for PA, PET, PUR, and PP fibers to improve weatherability and provide light stabilization.
