Tinuvin ® 1130 is an excellent UV absorber, and the following is a detailed introduction about it:

essential information:

Chemical name: 3- (3- (2-H-benzotriazole-2-yl) -4-hydroxy-5-tert-butylphenyl) - propionic acid polyethylene glycol 300 ester;

CAS login number: 104810-48-2;

Molecular weight: 353.41492 (there are also data showing the existence of polymer forms with different molecular weights).

physical property:

Appearance: yellow to light amber viscous liquid;

Dynamic viscosity (20 ° C): 8300 mPa · s;

Density (20 ° C): 1.15-1.19 g/cm ³;

Flash point: 216-220 ° C;

Solubility: Easily soluble in polar and non-polar solvents, but insoluble in water. It can be dissolved in some water-soluble solvents such as diethylene glycol diethyl ether for use in aqueous systems.

Performance characteristics:

Excellent weather resistance: It can strongly absorb ultraviolet rays, especially those with wavelengths of 290-400nm, effectively preventing damage to coatings, plastics, rubber and other materials by ultraviolet rays, thereby maintaining the performance and appearance stability of materials and extending their service life.

Good compatibility: It is easy to emulsify in water-based systems and has good compatibility with various coating systems (such as automotive coatings, industrial coatings, architectural coatings, etc.). It can be uniformly dispersed in the system without affecting the performance and appearance of the coating.

High temperature resistance and extraction resistance: It can maintain stable performance in high temperature environments, is not easy to evaporate and decompose, and has extraction resistance, which can maintain long-term effectiveness in materials.

Low volatility: It will not be lost due to volatilization during use, ensuring its long-term stability and effectiveness in the material.

Application areas:

Coatings industry: widely used in various solvent based or water-based coating systems such as automotive coatings, industrial coatings, architectural coatings, wood coloring coatings, etc. It can effectively prevent coatings from losing gloss, cracking, foaming, peeling, discoloration and other problems when exposed to sunlight for a long time, and improve the weather resistance and decorative properties of coatings.

Plastic industry: It can be used in plastic materials such as polycarbonate, polyurethane, polyester, acrylic resin, etc., to prevent plastic degradation, yellowing, brittleness and other phenomena under ultraviolet irradiation, and improve the weather resistance and mechanical properties of plastics.

Other fields: It can also be applied to adhesives, sealants, glass and ceramic coatings, wood stains and varnishes, wood products, wax, and other fields to provide UV protection for these materials.

Usage and precautions:

Usage: Tinuvin ® The addition amount of 1130 depends on the specific application field and requirements. Generally, the addition amount relative to the resin solid content in the coating system is 1.0-3.0%, and the addition amount in the plastic system is generally 0.1-1.0%. When in use, it needs to be evenly dispersed in the system, which can be achieved through stirring, grinding, and other methods.

Attention: As an industrial chemical, it should be avoided from contact with the skin. It is recommended to wear protective gloves and goggles during operation. The product should be stored in a dark, cool place and sealed after use.
