It has good heat resistance, durability, and efficient UV absorption ability, low volatility, good compatibility with the system, and stable color. Widely used in fields such as automotive, industrial, wood coatings, and plastics. Suggest adding 1.0-3.0%, which can be used in conjunction with other products. Improve the weather resistance and anti-aging performance of the product, and protect the material from UV damage.

Tinuvin® 384-2 is a liquid benzotriazole UV absorber produced by BASF. Here are some of its main features and application information:

characteristic:

Good heat resistance and durability: able to maintain stability under high temperature and extreme environmental conditions, suitable for coatings and other products exposed to such environments for a long time.

Efficient UV absorption capability: With a wide UV absorption spectrum, it can effectively absorb UV rays and provide good protection for light sensitive substrates such as wood and plastic.

Low volatility: It is not easily volatile during use and can maintain a long-lasting protective effect.

Good compatibility with the system: It has good dispersibility in aqueous systems and can maintain good compatibility with the system even at high concentrations; It also has good solubility in organic solvents, but is insoluble in water.

Good color stability: Its absorption spectrum is not obvious at the tail of the visible light region, which has a small impact on the color of the product and can maintain the initial color of the product.
 

Application areas:

Coating field: it is widely used in automotive coatings, industrial coatings (such as coil steel coatings), wood coatings, etc., which can improve the weather resistance and anti-aging performance of coatings, and prevent the degradation, discoloration, and loss of light of coatings due to ultraviolet radiation.

In the field of plastics, it can be used in plastic materials that require high photostability to enhance their UV resistance.

Other fields: It also has certain applications in products such as adhesives and sealants.
