Tinuvin ® 99-2 is a light stabilizer from BASF. For liquid hydroxyphenyl benzotriazole products, it has high UV absorption capacity and good thermal stability, and is compatible with various solvents. Commonly used in commercial coatings, such as wood dyeing systems, varnishes, and industrial coatings. Can protect photosensitive substrates and provide photostability protection for materials. But the color is darker and should be used with caution in systems with high color requirements.
 

characteristic:

Efficient UV absorption capability: It can effectively absorb UV rays from sunlight, reduce the damage of UV rays to materials, prevent material aging, fading, and degradation, and provide good light stability protection for materials.

Good thermal stability: able to maintain stable performance in high temperature environments, suitable for coatings and other systems exposed to high temperature conditions, and can meet some application needs that require high-temperature baking processes.

Good compatibility with multiple solvents: It can dissolve in most coating solvents at a high proportion, such as butanol, aromatic oil solvents, butyl carbitol, acetic acid propylene glycol methyl ether, etc., which makes it easy to add and disperse in coating formulations.
 

Application areas:

Coatings industry: commonly used for commercial sales of coatings, especially wood dyeing systems and varnishes, which can protect photosensitive substrates such as wood; It is also applicable to general industrial coatings and high-temperature baking industrial systems, such as coil steel coatings.

Plastic industry: Although its application in the plastic field is relatively less mentioned, based on its photostability, it may also have certain potential for application in some plastic products that require high weather resistance.
