Anti-yellowing agent for PU

The anti-yellowing agent for PU provides photochemical stabilization through absorption of UV radiation and suppression of free radical reactions. It integrates easily into PU prepolymer systems and maintains performance even under repeated thermal cycles. Applicable to both aromatic and aliphatic PU systems, it offers excellent compatibility, transparency retention, and durability for coatings, adhesives, and elastomers.
