Features Of BASF Tinuvin 477-DW Red-Shifted UVA for Waterborne Coatings

  1. Red-shifted absorption profile optimized for enhanced protection against long-wave UVA (380–400 nm) in waterborne systems.

  2. Excellent compatibility and stability in acrylic, styrene-acrylic, and polyurethane dispersions without causing haze or viscosity drift.

  3. Low volatility and non-migrating design ensure durable photostabilization throughout coating service life.

  4. Designed specifically for low-VOC, high-solids, and zero-NMP waterborne architectural and industrial coatings.

  5. Enables improved gloss retention and reduced chalking in exterior façade and cladding applications exposed to intense sunlight.

Typical Applications Of BASF Tinuvin 477-DW Red-Shifted UVA for Waterborne Coatings

  1. Exterior architectural waterborne paints for façades, stucco, and concrete substrates.

  2. Waterborne industrial maintenance coatings for metal structures and infrastructure.

  3. High-performance waterborne wood coatings for windows, doors, and cladding.

  4. Interior/exterior waterborne elastomeric wall coatings requiring extended UV resistance.

  5. UV-stabilized waterborne primers and topcoats for prefabricated building panels.
