The harmful effects of the sun's ultraviolet (UV) rays on the skin and other materials are well-known. These rays can cause skin cancer, premature aging, fading of fabrics, and degradation of plastics and other materials. That's why it's crucial to use effective UV absorbers and stabilizers to protect ourselves and our belongings from the damaging effects of UV radiation. One such product is Ultraviolet Absorber UV 99-2, also known as BASF TINUVIN 99-2 or Light Stabilizer UV 99-2. This advanced UV absorber is produced by Ningbo Inno Pharmchem Co., Ltd., a trusted factory and supplier of high-quality chemicals and pharmaceutical intermediates.

UV 99-2 is a benzotriazole derivative that effectively absorbs UV rays in the range of 290-400 nm, which is the most damaging part of the UV spectrum. It belongs to the class of hindered amine light stabilizers (HALS), which not only absorb UV radiation but also prevent the degradation of polymers and other materials by neutralizing the free radicals that are generated by UV exposure. This makes UV 99-2 a versatile and effective additive for a wide range of applications, including coatings, plastics, fibers, films, and adhesives.

One of the main advantages of UV 99-2 is its high efficiency and durability. It has a strong absorption peak at 340 nm, which is close to the maximum intensity of the sun's UV radiation. This means that it can effectively block most of the harmful UV rays that cause skin damage and material degradation. Moreover, UV 99-2 has excellent thermal stability and resistance to weathering, which means that it can maintain its UV protection for a long time even under harsh conditions. It also has low volatility and migration, which makes it suitable for use in outdoor applications where exposure to rain, wind, and dust is common.

Another benefit of UV 99-2 is its compatibility with various resins and polymers. It can be easily dispersed in waterborne, solvent-based, or powder coatings, as well as in polyolefins, PVC, PET, and other plastics. It does not affect the color, transparency, or other properties of the substrate, and it can improve the gloss, adhesion, and scratch resistance of the coating. In addition, UV 99-2 can be used in combination with other UV absorbers and stabilizers to achieve synergistic effects and enhance the overall performance of the system.

UV 99-2 is also a safe and eco-friendly product. It does not contain heavy metals, formaldehyde, or other hazardous substances that can harm human health or the environment. It complies with the regulations of REACH, FDA, and other international standards for chemical safety and quality. It is also easy to handle and transport, as it is available in various forms such as powder, granule, or liquid.

Ningbo Inno Pharmchem Co., Ltd. is a leading manufacturer and supplier of UV 99-2 and other high-quality chemicals and intermediates. The company has a state-of-the-art production facility that uses advanced equipment and technology to ensure the purity, consistency, and stability of its products. It also has a team of experienced chemists and engineers who can provide technical support and custom solutions to meet the specific needs of customers.

In conclusion, UV 99-2 is an advanced ultraviolet absorber and light stabilizer that offers optimal sun protection for various materials and applications. It is efficient, durable, compatible, safe, and eco-friendly, making it a popular choice among manufacturers and users worldwide. If you're looking for a trusted supplier of UV 99-2 or other chemicals, you can rely on Ningbo Inno Pharmchem Co., Ltd. to provide you with high-quality products and services.
