Basic Information and Parameters

The Factory Supply uv absorber 928 with CAS number 73936 - 91 - 1 is a high - quality UV absorber designed to provide excellent protection against ultraviolet radiation. It is a light - colored, low - volatility liquid or solid, depending on the specific formulation.

Technical parameters include its chemical formula, which is specifically tailored to absorb UV light within a certain wavelength range, typically in the UV - A and UV - B regions. Its molecular weight is precisely calculated to ensure optimal performance and compatibility with various polymers and coatings. The purity of this product is usually maintained at a very high level, often above 99%, which guarantees its effectiveness in UV protection.

Uses of the Product

This uv absorber 928 has a wide range of applications. In the plastics industry, it is used to prevent the degradation of polymers caused by UV light. When added to plastic products such as PVC, polycarbonate, and polyethylene, it can significantly extend the service life of these materials, maintaining their mechanical properties, color stability, and transparency.

In the coatings industry, it is an essential additive for exterior paints, automotive paints, and wood coatings. By adding this UV absorber, the coatings can resist yellowing, cracking, and chalking, providing long - lasting protection and a beautiful appearance for the substrates.

It is also used in the textile industry to protect fibers from UV damage, which is especially important for outdoor clothing, awnings, and tents.

How to Use the Product

The usage of uv absorber 928 depends on the specific application. In plastics, it can be added during the extrusion or molding process. The recommended dosage is usually between 0.1% - 1% by weight, depending on the type of plastic, the expected level of UV protection, and the environmental conditions.

For coatings, it can be incorporated into the coating formulation during the mixing stage. It should be well - dispersed in the coating to ensure uniform UV protection. A proper dispersing agent may be required to achieve the best results.

When using in textiles, it can be applied through a padding or spraying process. The concentration and processing conditions need to be adjusted according to the fabric type and the required protection level.

Detailed Use Cases

Case 1: A plastic product manufacturer produced PVC window profiles. After adding Factory Supply uv absorber 928 at a dosage of 0.5% by weight, they conducted a long - term outdoor exposure test. After 2 years of exposure, the window profiles maintained their original color and gloss, and there was no significant loss of mechanical properties. In contrast, the profiles without the UV absorber showed obvious yellowing, cracking, and a decrease in impact strength.

Case 2: An automotive paint company added this UV absorber to their exterior car paints. In a salt - spray and UV - combined test, the painted car body showed excellent resistance to corrosion and UV damage. The paint maintained its smoothness and color for a much longer time compared to the paint without the UV absorber.

Case 3: A textile company applied the uv absorber 928 to their outdoor tent fabric. Through a spraying process, the tent fabric gained excellent UV protection. Customers reported that the tent did not fade or become brittle even after several seasons of outdoor use.
