Songwon HALS
Songwon HALS is a category of Hindered Amine Light Stabilizers designed to help protect plastics, coatings, and polymer materials from degradation caused by light exposure, heat, and outdoor conditions. HALS products work by scavenging free radicals formed during photo-oxidation, helping preserve colour, mechanical properties, surface quality, and material service life.
In polymer and coating formulations, HALS are commonly used to improve light stability, weathering resistance, long-term durability, and protection against cracking, chalking, discoloration, and performance loss caused by UV exposure. Songwon offers various HALS options, including low molecular weight HALS, high molecular weight HALS, polymeric HALS, liquid HALS, and UVA/HALS/AO blends for different application requirements.
