In the field of the chemical industry, UV absorbers play a crucial role, particularly in protecting materials from UV damage. Today, we will delve into a highly regarded UV absorber—Tinuvin 1130.

Tinuvin 1130:
chemical name: 3-(3-(2H-benzotriazole-2-yl)-4-hydroxy-5-tert-butylphenyl)propionic acid polyethylene glycol 300 ester;
CAS login number: 104810-48-2.
This product is an exceptional UV absorber that offers numerous benefits due to its unique properties.

One of the standout features of Tinuvin 1130 is its excellent weather resistance. It has a strong ability to absorb ultraviolet rays, particularly those with wavelengths ranging from 290-400nm. This effectively prevents coatings, plastics, rubber, and other materials from being damaged by UV rays, thereby maintaining the performance and appearance stability of these materials and extending their service life.

In addition, Tinuvin 1130 exhibits good compatibility. It is easy to emulsify in water-based systems and can be uniformly dispersed in various coating systems, such as automotive coatings, industrial coatings, and architectural coatings, without affecting the performance and appearance of the coating. This makes it a versatile choice for a wide range of applications.

The product's high temperature resistance and extraction resistance are also noteworthy. It can maintain stable performance in high temperature environments, is not easy to evaporate and decompose, ensuring long-term effectiveness in materials. Furthermore, its low volatility means that it will not be lost due to volatilization during use, thereby ensuring its long-term stability and effectiveness in the material.

Due to these exceptional properties, Tinuvin 1130 is widely used in various industries. In the coatings industry, it is applied to various solvent-based or water-based coating systems, such as automotive coatings, industrial coatings, and architectural coatings. It can effectively prevent coatings from losing gloss, cracking, foaming, peeling, and discoloration when exposed to sunlight for an extended period, thus enhancing the weather resistance and decorative properties of coatings. In the plastic industry, it is used in plastic materials such as polycarbonate, polyurethane, polyester, and acrylic resin to prevent degradation, yellowing, and brittleness under ultraviolet irradiation, thereby improving the weather resistance and mechanical properties of plastics.

When using Tinuvin 1130, it is important to follow the recommended usage and precautions. The addition amount depends on the specific application field and requirements. Generally, the addition amount relative to the resin solid content in the coating system is 1.0-3.0%, and the addition amount in the plastic system is typically 0.1-1.0%. It should be evenly dispersed in the system through stirring, grinding, and other methods. As an industrial chemical, it should be handled with care to avoid skin contact. Operators are advised to wear protective gloves and goggles during use. The product should be stored in a dark, cool place and sealed after use to ensure its quality and safety.

In summary, Tinuvin 1130 is an excellent UV absorber that offers numerous benefits due to its unique properties. Its excellent weather resistance, good compatibility, high temperature resistance, extraction resistance, and low volatility make it a versatile choice for various applications in the coatings and plastic industries. With proper usage and precautions, Tinuvin 1130 can effectively protect materials from UV damage, ensuring the quality, safety, and durability of finished products.
