The product, Factory Supply UV Absorber 2908 Cas 67845-93-6, is a high - quality UV absorber provided directly from the factory at a competitive price. The CAS number 67845 - 93 - 6 uniquely identifies this chemical compound in the scientific and industrial fields.
Physically, it may appear as a fine powder or a liquid, depending on the specific manufacturing process. The purity of this UV absorber is usually maintained at a high level to ensure its effectiveness. It has a specific melting point and boiling point range, which are important parameters for storage and processing. The density of the product also affects its solubility and compatibility with other substances.
Some key chemical properties include its high absorption efficiency in the ultraviolet spectrum range, which allows it to provide excellent UV protection for various materials. It is also stable under normal environmental conditions, resistant to heat and oxidation to a certain extent.
UV Absorber 2908 finds wide applications in multiple industries. In the plastics industry, it can be added to plastic products such as polypropylene, polyethylene, and PVC. By absorbing harmful UV rays, it helps to prevent the plastic from discoloration, embrittlement, and loss of mechanical properties, thereby extending the service life of plastic products. For example, it is used in outdoor plastic furniture, which is exposed to sunlight for long periods.
In the coating industry, this UV absorber can be incorporated into paints and varnishes. It protects the underlying substrate from UV - induced degradation and also enhances the durability and appearance of the coating. Architectural coatings, automotive paints, and industrial coatings can all benefit from its addition.
It is also used in the textile industry. When added to textile fibers or finishes, it provides UV protection for fabrics, making them more suitable for outdoor clothing, awnings, and other sun - exposed textile products.
When using UV Absorber 2908, it is crucial to follow the recommended dosage. The dosage typically depends on the specific application and the type of material being protected. For plastics, the general dosage may range from 0.1% to 1% by weight. It should be uniformly mixed with the plastic resin during the processing stage, such as during extrusion or injection molding.
In coatings, it can be added during the formulation process. The absorber should be thoroughly dispersed in the coating system to ensure even UV protection across the entire coated surface. It is advisable to perform small - scale tests first to determine the optimal dosage and compatibility with other coating components.
For textiles, it can be applied through padding or spraying methods. The concentration of the treatment solution and the processing conditions need to be carefully controlled to achieve the desired UV protection effect.
Case 1: A plastic manufacturer producing outdoor plastic chairs incorporated UV Absorber 2908 into their polypropylene resin. Before using the absorber, the chairs would start to show signs of yellowing and becoming brittle after just a few months of outdoor exposure. After adding the UV absorber at a dosage of 0.5% by weight, the chairs retained their original color and mechanical strength even after a year of continuous outdoor use. This significantly improved the product quality and customer satisfaction, leading to an increase in sales.
Case 2: An automotive paint supplier added UV Absorber 2908 to their top - coat paint formulation. The paint was used on a new car model. During accelerated weathering tests, the painted car panels with the absorber showed much less fading and gloss loss compared to the panels without the absorber. In real - world use, the cars maintained their vibrant color and smooth finish for a longer time, enhancing the overall aesthetic appeal and resale value of the vehicles.
Case 3: A textile company treated their outdoor awning fabric with a solution containing UV Absorber 2908. The treated fabric had a much higher UPF (Ultraviolet Protection Factor) rating compared to the untreated fabric. This made the awnings more effective in blocking UV rays, providing better shade and protection for the users. As a result, the company was able to expand its market share in the outdoor shading product segment.
