Before we dive into the differences, it's essential to understand what PU hardeners are. Polyurethane hardeners are compounds that, when combined with a resin, facilitate the curing process, transforming a liquid mixture into a solid, durable product. These hardeners play a crucial role in enhancing the overall performance, resistance, and longevity of the coating.
Traditional polyurethane hardeners have long been used in various applications, from floor coatings to varnishes. However, one significant downside of these hardeners is their tendency to yellow over time. This yellowing can detract from the aesthetic appeal of a finish, particularly for clear coats and light-colored surfaces. The discoloration not only affects the beauty of the project but can also compromise the integrity of color-sensitive applications.
The yellowing process is often caused by exposure to UV light and certain environmental conditions. Over time, traditional hardeners can break down, leading to color changes that may be irreversible. This phenomenon is particularly problematic in applications that demand clarity and precision, such as art restoration, furniture refinishing, and automotive coatings.
Non-yellowing PU hardener addresses these specific issues. Designed with advanced formulations, this type of hardener offers greater resistance to UV degradation, thereby maintaining the original appearance of the finish for much longer. Whether you’re working on a home improvement project or a professional application, the benefits of a non-yellowing hardener are clear.
One of the most significant advantages of non-yellowing PU hardeners is their ability to maintain clarity. Unlike traditional options, these hardeners resist the yellowing process, ensuring that your finishes remain crystal clear, enhancing the beauty of your work.
