Anti-yellowing additive for polyurethane

The anti-yellowing additive for polyurethane contains a synergistic blend of UV absorbers and free-radical scavengers that protect PU systems from photo-oxidative degradation. It’s compatible with both solvent-based and waterborne polyurethane systems, providing uniform dispersion and long-term stability. It retains clarity and elasticity, resisting thermal yellowing even under continuous heat exposure. Recommended for high-transparency coatings, flexible foam formulations, and elastomers exposed to outdoor conditions.
