Non-yellowing PU hardeners are specialized formulations designed to cure polyurethane finishes while maintaining their clarity over time. Traditional polyurethane products often yellow due to exposure to UV light, heat, and environmental factors. This yellowing not only affects aesthetics but can also impact the integrity and durability of the finish. Non-yellowing PU hardeners provide a lasting solution, protecting your work from discoloration and ensuring a longer-lasting, vibrant appearance.
