Selecting the optimal UV stabilizer is a critical decision for any coating manufacturer aiming for long-term performance and aesthetic integrity. While various types of UV protection additives exist, including HALS and other UV absorbers, understanding their specific strengths and ideal applications is key. This guide aims to highlight why our UV Absorber 928 stands out, especially for demanding sectors like automotive, powder, and coil coatings.

UV absorbers, such as the hydroxyphenyl benzotriazole class to which UV Absorber 928 belongs, work by absorbing UV radiation and converting it into heat. This process effectively shields the polymer matrix from photodegradation. Compared to HALS, which act as radical scavengers, UV absorbers offer a direct mechanism of protection by intercepting UV light before it can initiate damaging reactions. This makes them a primary line of defense, especially in applications where direct UV exposure is intense.

What makes UV Absorber 928 a preferred choice for many formulators? Firstly, its performance in high-temperature curing processes is exceptional. Many modern coating applications, including powder and coil coatings, require elevated curing temperatures that can degrade less stable UV absorbers. UV Absorber 928 maintains its efficacy under these conditions, ensuring consistent protection throughout the product's lifecycle. Secondly, its excellent solubility allows for homogeneous dispersion within coating formulations, preventing issues like blooming or uneven protection – problems that can arise with less compatible additives.

When considering automotive coatings, the need for superior color retention and gloss stability is non-negotiable. UV Absorber 928 delivers on these fronts, protecting the vibrant finishes from UV-induced fading and hazing. Similarly, for powder and coil coatings used in exterior architectural applications or demanding industrial environments, its high thermal and environmental permanence ensures that the protective layer remains intact, resisting cracking and delamination caused by UV exposure.
