The Factory Supply ultraviolet absorbent uv - 2 with CAS number 65816 - 20 - 8 is a high - quality product offered at a low price. This ultraviolet absorbent is designed to effectively absorb ultraviolet rays, providing protection for various materials.
Physical and chemical properties:
- Appearance: Usually, it comes in a powder or granular form, which is easy to handle and mix.
- Solubility: It has good solubility in some common organic solvents, which allows for easy incorporation into different formulations.
- Melting point: The specific melting point may vary depending on the purity and manufacturing process, but it generally falls within a certain range suitable for industrial applications.
- UV absorption spectrum: It has a broad absorption spectrum in the ultraviolet region, which can effectively absorb UV - A and UV - B rays.
This ultraviolet absorbent uv - 2 has a wide range of applications in multiple industries:
1. Plastics industry: It can be added to plastic products such as polycarbonate, polyethylene, and polypropylene. By absorbing ultraviolet rays, it helps prevent the degradation of plastics caused by UV exposure, thereby extending the service life of plastic products and maintaining their appearance and performance. For example, in outdoor plastic furniture, it can prevent the fading and cracking of the plastic surface.
2. Coating industry: In paint and coating formulations, the addition of uv - 2 can enhance the UV resistance of the coating. This is especially important for exterior coatings, as it can protect the substrate from UV damage and keep the coating looking fresh and intact for a longer time.
3. Rubber industry: In rubber products, it can improve the anti - aging properties of rubber. Rubber products exposed to sunlight for a long time are prone to hardening, cracking, and losing elasticity. The use of this ultraviolet absorbent can effectively slow down these processes.
The usage of the ultraviolet absorbent uv - 2 is relatively straightforward, but some key points need to be noted:
1. Dosage: The appropriate dosage depends on the specific application and the requirements of the final product. Generally, for plastics, the dosage is usually in the range of 0.1% - 5% of the total weight of the plastic resin. For coatings, it may be around 1% - 3% of the coating formulation. It is recommended to conduct small - scale tests first to determine the optimal dosage.
2. Mixing: When adding uv - 2 to the material, ensure thorough mixing. For plastics, it can be mixed with the plastic resin during the melting or granulation process. In the coating industry, it should be evenly dispersed in the coating under high - speed stirring.
3. Storage: The product should be stored in a cool, dry place, away from direct sunlight and heat sources. Keep the packaging sealed to prevent moisture absorption and oxidation, which may affect the performance of the product.
Case 1: A plastic product manufacturing company produced outdoor plastic chairs. Before using the uv - 2, the chairs would start to show signs of fading and cracking after 6 months of outdoor exposure. After adding 2% of uv - 2 to the plastic resin, the chairs maintained their original color and shape even after 2 years of outdoor use, significantly improving the product quality and customer satisfaction.
Case 2: A coating company applied a coating with uv - 2 on the exterior walls of a building. The building was located in a region with strong sunlight. After 3 years, the coating still looked new, with no obvious peeling or color change, while the neighboring buildings without the uv - 2 - enhanced coating showed significant signs of deterioration.
