High Quality tinuvin - 1130 is a well - known and widely used light stabilizer. Its CAS numbers are 104810 - 48 - 2 and 104810 - 47 - 1. This product is recognized for its high purity and excellent performance, meeting strict industry standards. It has a specific chemical structure that enables it to effectively absorb and dissipate harmful ultraviolet (UV) radiation.
The appearance of tinuvin - 1130 is usually a clear to slightly yellowish liquid. It has good solubility in a variety of organic solvents, which makes it easy to incorporate into different formulations. In terms of stability, it can maintain its chemical properties under normal storage conditions, ensuring a long shelf - life.
Tinuvin - 1130 is mainly used as a light stabilizer in the polymer and coatings industries. In the polymer field, it can be added to various plastics such as polypropylene (PP), polyethylene (PE), and polyurethane (PU). By protecting polymers from UV damage, it helps to prevent degradation, such as cracking, yellowing, and loss of mechanical properties. This extends the service life of plastic products, making them more suitable for outdoor applications, like automotive parts, outdoor furniture, and agricultural films.
In the coatings industry, tinuvin - 1130 is an essential additive. It enhances the durability and weather - resistance of coatings, ensuring that painted surfaces maintain their color and gloss even when exposed to sunlight and harsh environmental conditions. Coatings with tinuvin - 1130 are commonly used in architectural coatings, automotive coatings, and industrial coatings.
When using High Quality tinuvin - 1130, it is important to follow proper procedures. First, determine the appropriate dosage based on the specific application and the type of substrate. Generally, the recommended dosage ranges from 0.1% to 3% by weight, depending on the level of UV protection required and the nature of the polymer or coating system.
For polymers, the product can be added during the extrusion or compounding process. Ensure thorough mixing to achieve a homogeneous distribution of the stabilizer in the polymer matrix. In coatings, tinuvin - 1130 can be added during the formulation stage. Stir the mixture well to ensure it is completely dissolved and evenly dispersed.
Case 1: Automotive Industry
In an automotive manufacturing company, they used a polypropylene - based plastic for interior and exterior parts. After adding tinuvin - 1130 at a dosage of 0.5%, they conducted accelerated weathering tests. The results showed that the plastic parts maintained their original color and mechanical strength even after equivalent exposure to several years of outdoor sunlight. This not only improved the aesthetic appearance of the vehicles but also enhanced the overall quality and reliability of the automotive components.
Case 2: Architectural Coatings
A large - scale building project used exterior coatings with tinuvin - 1130. The building was located in a region with high sunlight intensity and frequent temperature fluctuations. After two years of exposure, the coating on the building facade still looked as good as new, with no signs of fading, chalking, or cracking. This saved the building owner from the cost and inconvenience of frequent repainting.
