UV-928 Application scenarios

1. High-Performance Coatings

This is its most core and prominent application area. Thanks to its excellent thermal stability and good solubility, it is particularly suitable for coating systems requiring high-temperature curing.

– Powder Coatings

Prevents decomposition during high-temperature baking, effectively protecting the coating from loss of gloss, discoloration, and cracking.

– Coil Coatings (Coated Steel)

Used for pre-coated metal coils, providing long-term weather protection.

– Automotive Coatings

Used in original equipment manufacturer (OEM) paints or refinish paints to improve the long-term weather resistance and anti-yellowing properties of the paint surface.

– Other Industrial Coatings

The general addition amount is 1.0% – 3.0% of the total weight of the formula, and it is often used in combination with hindered amine light stabilizers (such as UV-292) for better results.

2. High-End Engineering Plastics

Used as a high-efficiency light stabilizer to protect the mechanical properties and appearance of plastics.

– Polycarbonate (PC)

Significantly improves the anti-yellowing ability of polycarbonate.

– Polyesters (such as PBT, PET)

Prevents strength and color degradation caused by ultraviolet light.

– Polyamide (PA, Nylon), Polyoxymethylene (POM), Polyphenylene Sulfide (PPS), etc.

The recommended addition amount is usually between 0.15% and 0.60%.

3. Agricultural Films

Added to agricultural plastic films, it can absorb some ultraviolet light, extending the service life of the film while also helping to create a more suitable growth and development environment for certain crops.

4. Perekat dan Sealant

Used in adhesives and sealants that require long-term outdoor use or may be affected by sunlight, preventing aging and failure due to ultraviolet radiation.

5. Scientific Research Applications

This compound is also provided as a biochemical reagent, mainly used in related light stabilization mechanism research and material development experiments.

Penggunaan UV-928

1. Penyerap UV UV-928 adalah penyerap UV benzotriazol, yang mampu menyerap sinar UV 270-380nm, dengan penyerapan puncak 303nm dan 343nm. Ini memiliki kompatibilitas yang baik, volatilitas rendah, dispersibilitas yang baik, migrasi rendah, stabilitas termal yang baik dan efisiensi penyerapan yang tinggi. Sangat cocok untuk sistem pengawetan suhu tinggi, pelapis bubuk, pelapis baja koil, dan terutama untuk pelapis permukaan pelapis. Dikombinasikan dengan penstabil cahaya UV292 dan UV123, secara signifikan dapat meningkatkan daya tahan lapisan dan menghambat hilangnya cahaya, perubahan warna, retak dan delaminasi lapisan. Dosis umum adalah 1.0-3.0%.

2. Berlaku untuk: Penyerap UV untuk pelapis berkinerja tinggi. Dengan berbagai sifat penyerapan, secara efektif dapat melindungi pelapis dan bahan fotosensitif lainnya. Juga memiliki kelarutan yang tinggi, tahan suhu tinggi dan daya tahan lingkungan yang baik, terutama cocok untuk sistem pengawetan suhu tinggi, seperti pelapis bubuk, pelapis baja koil, dll.
