Tinuvin® 900 is BASF's ultraviolet absorber. A slightly yellow powder with excellent thermal and photostability, efficient UV absorption capacity, and good compatibility. Widely used in fields such as coatings and plastics. Improve the weather resistance and anti-aging performance of the product to prevent aging and fading. Often used in combination with light stabilizers, it is recommended to adjust the dosage according to specific needs to provide long-lasting and effective protection for the material, meeting the performance requirements of different industries.
 

Tinuvin® 900 is a UV absorber produced by BASF in Germany. Here are some of its main features and related information:

Basic attributes:

Chemical name: 2- (2H-Benzotriazol-2-yl) -4,6-di (1-methyl-1-phenylethyl) - phenol.

Appearance: Slightly yellow powder.

Molecular weight: 447.6 g/mol.

Melting point: 137-141 ℃.

Solubility: soluble in most organic solvents, insoluble in water.
 

Performance characteristics:

Excellent thermal and photostability: Developed specifically for coating systems exposed to high temperatures and extreme environmental stresses, it can maintain good performance under harsh environmental conditions and is not easily decomposed or failed.

Efficient UV absorption capacity: It has a wide and efficient absorption of UV rays, which can effectively protect materials such as coatings, plastics, rubber, etc. from UV damage, prevent materials from aging, fading, brittleness and other problems.

Good compatibility: It has good compatibility with various coating systems and polymer materials, can be evenly dispersed in the material, and plays a stable protective role.

Application areas:

Coating industry: it is widely used in automotive coatings, coil coatings, industrial coatings, powder coatings, etc., which can improve the weather resistance and anti-aging performance of coatings, and prevent the coating from gloss reduction, cracking, blistering, layering, color change and other problems when exposed to the sun for a long time.

Plastic industry: It can be used in plastic materials that require high light stability to enhance the UV resistance of plastics and extend the service life of plastic products.

Usage suggestion: It is usually recommended to use it in combination with light stabilizers such as hindered amine (HALS) to achieve better protective effects. Suggested dosage is 1-3% Tinuvin ® 900 plus 0.5-2% Tinuvin 144, Tinuvin 292, or Tinuvin 123, etc. The specific usage amount needs to be adjusted according to the application scenario and specific requirements.
