Tinuvin ® 400-DW ECO is a light stabilizer product launched by BASF. Here are some detailed information about it:

Basic characteristics:

Efficient light stability performance: As a UV absorber, it can effectively absorb UV rays in the wavelength range of 290-400nm, prevent UV damage to materials, reduce aging, fading, brittleness and other problems caused by light exposure, and thus extend the service life of materials.

Good thermal stability: able to maintain stable performance at high temperatures, suitable for materials that require high-temperature processing or use in high-temperature environments, such as maintaining good light stability during the baking process of automotive coatings.

Low mobility: The migration effect in the material is relatively low, and it can maintain its effectiveness in the material for a long time without causing a decrease in photostability due to migration.

Environmental friendliness: The label "DW ECO" indicates that it has certain environmentally friendly characteristics, which may be due to reducing the use or emission of harmful substances in the production process, or having advantages in product degradability and other aspects, meeting environmental protection requirements.

Application areas:

Coatings industry: widely used in various coating systems, such as automotive coatings, industrial coatings, architectural coatings, etc. In automotive coatings, it can provide good appearance protection for cars, preventing problems such as paint fading and cracking when the body is exposed to sunlight for a long time; In industrial coatings, it can protect industrial equipment, steel structures, etc. from UV erosion; In architectural coatings, the weather resistance of the coating can be improved to maintain the appearance of the building for a long time.

Ink industry: Suitable for water-based ink, it can prevent ink from fading or changing color after printing due to ultraviolet radiation, ensuring the quality and color stability of printed products.

Plastic industry: can be used in plastic materials to enhance the weather resistance of plastics, improve the stability and service life of plastic products when used outdoors. For example, Tinuvin can be added to products such as plastic films, plastic pipes, and plastic containers ® 400-DW ECO is used to improve its light resistance performance.

Usage: When using, it needs to be evenly dispersed in the material system, and the specific amount of addition may vary depending on different application scenarios and material requirements. Generally speaking, in coating systems, the amount of resin solids added is usually between 1.0% and 3.0%. When used in combination with other additives or additives, attention should be paid to their compatibility and synergistic effects to achieve the best light stabilization effect.
