Anti-yellowing additive for PU

The anti-yellowing additive for PU uses synergistic stabilizers that block UV absorption and neutralize peroxides formed during thermal oxidation. It resists discoloration during curing and long-term use. This additive disperses uniformly in the polymer matrix without affecting viscosity or curing behavior, making it suitable for PU coatings, adhesives, and injection-molded products.
