The product, named High Quality Light Stabilizer 944 CAS 70624-18-9 With Low Price, is a high - performance light stabilizer. The CAS number 70624 - 18 - 9 uniquely identifies this chemical compound in the chemical industry. It is known for its excellent light - stabilizing properties, which can effectively protect polymers and other materials from the damage caused by ultraviolet (UV) light. The low price makes it an economically viable option for various industries.
The chemical structure of Light Stabilizer 944 is designed to capture free radicals generated by the interaction of materials with UV light, thereby preventing the degradation of materials such as discoloration, cracking, and loss of mechanical properties. It has good compatibility with a wide range of polymers, including polyolefins, styrenics, and engineering plastics.
This light stabilizer has a wide range of applications in many industries. In the plastics industry, it can be added to plastic products such as plastic pipes, automotive interior and exterior parts, and plastic packaging materials. By adding Light Stabilizer 944, these plastic products can maintain their original physical and mechanical properties and appearance for a longer time under sunlight or artificial UV light, enhancing their service life and durability.
In the coating industry, it can be used in various coatings, including automotive coatings, architectural coatings, and industrial coatings. The addition of this stabilizer can improve the weather resistance of the coatings, prevent the coatings from fading, chalking, and peeling, and keep the coatings looking fresh and beautiful for a long time.
In the rubber industry, it can be used to improve the UV resistance of rubber products, such as tires, rubber seals, and rubber hoses. This can significantly extend the service life of rubber products in outdoor environments.
Before using High Quality Light Stabilizer 944, it is necessary to conduct a small - scale test to determine the optimal dosage according to the specific material and application requirements. Generally, the recommended dosage ranges from 0.1% to 1.0% by weight of the polymer or coating material.
When using it in plastics, it can be added during the plastic compounding process. First, mix the stabilizer with the plastic resin evenly, and then carry out the subsequent processing steps such as extrusion, injection molding, or blow molding. In the coating industry, it can be added to the coating formulation during the production process, and thorough stirring is required to ensure uniform dispersion. For rubber products, it can be added during the rubber mixing process.
Case 1: Automotive Interior Parts. A car manufacturer was facing the problem of discoloration and embrittlement of its plastic interior parts after long - term exposure to sunlight. By adding 0.5% of Light Stabilizer 944 to the polypropylene resin used for interior parts, the problem was effectively solved. After a 2 - year outdoor exposure test, the interior parts maintained their original color and flexibility, and the mechanical properties only showed a slight decrease, which was well within the acceptable range.
Case 2: Architectural Coatings. An architectural coating company used Light Stabilizer 944 in its exterior wall coatings. After applying the coatings on a building facade, the coatings showed excellent weather resistance. After 3 years of exposure to various weather conditions including strong sunlight, rain, and wind, the coatings still looked as good as new, without significant fading or chalking.
