Aliphatic Polyurethane vs. Aromatic Polyurethane: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 11, 2024
Aliphatic polyurethane is more UV-resistant and color-stable, while aromatic polyurethane is less UV-resistant but generally stronger and more economical.

Key Differences

Aliphatic polyurethane is characterized by its resistance to ultraviolet (UV) light and its ability to maintain color clarity over time. Aromatic polyurethane, on the other hand, tends to yellow and degrade under UV exposure, making it less suitable for outdoor applications.
