As the sun shines down on us, it brings warmth and light, but it also brings harmful UV rays that can damage our skin and our belongings. UV rays can cause fading, yellowing, cracking, and brittleness in materials such as plastics, coatings, and textiles. This is where BASF's Tinuvin 328 comes in, providing excellent UV protection to ensure that your products are durable and long-lasting.

BASF Tinuvin 328, also known as UV Absorber UV-328 or Light Stabilizer UV-328, is a highly effective UV absorber that is widely used in the plastics and coatings industry. It is a phenolic compound that belongs to the family of hydroxyphenyl benzotriazoles, which are known for their excellent UV absorption properties.

Tinuvin 328 is a light yellow powder that is insoluble in water and soluble in organic solvents. It has a molecular weight of 447.7 g/mol and a melting point of 139-141 °C. Its chemical name is 2-(2H-benzotriazol-2-yl)-4,6-di-tert-amylphenol, and its molecular formula is C30H50N6O.

Tinuvin 328 is an effective UV absorber that can absorb UV radiation in the range of 290-400 nm. It works by absorbing the UV radiation and converting it into heat, which is then dissipated into the surrounding environment. This prevents the UV radiation from reaching the substrate and causing damage.

Tinuvin 328 is highly effective in protecting a wide range of substrates, including polyolefins, polystyrenes, polyesters, acrylics, styrene copolymers, and polyamides. It is also compatible with other stabilizers, such as hindered amine light stabilizers (HALS) and antioxidant stabilizers, to provide a complete UV protection system.
