[Chemical name]: BIS(1-OCTYLOXY-2,2,6,6-TETRAMETHYL-4-PIPERIDYL) SEBACATE
[Chemical structure]:
[CAS NO]: 129757-67-1
[Molecular formula]: C44H84O6N2[Molecular weight]: 736
[Main Uses]: Used as Light stabilizer, suitable for polypropylene, high-density polyethylene, polyurethane, polystyrene, ABS resin, etc., its light stabilization effect is better than the commonly used Light stabilizer. When used in combination with antioxidants, it can improve heat resistance, and when used in combination with ultraviolet light absorbers, it also has a synergistic effect, which can further improve the light stabilization effect.

Light stabilizer XY-UV123
Xinyue XY-UV123 is a new type of hindered amine stabilizer of liquid amino ether. Particularly recommended application areas: automotive coatings, industrial coatings, decorative coatings, wood coatings and varnishes. It is specially developed for high solid content, acid catalyzed automotive coatings and industrial coatings such as two coat metallic thermoset acrylic metallic glitter systems or single coat thermoset acrylic varnish and polyester systems.
Its excellent performance is reflected in the following applications:
Alkyd resin/acrylate air-drying automotive refinish paint;
Oxidized alkyd paints and varnishes;
Two component non-isocyanate coating.
In addition, the liquid Xinyue XY-UV123 is easy to emulsify in water-based paint systems, and can also be used in various water-based paints. The product has a low alkalinity, which can minimize the reaction with the acidic components in the coating. It can effectively improve the life of varnish and reduce defects such as preventing varnish from cracking and gloss disappearing, and can also prevent color paint from chalking.
The combination of Xinyue XY-UV123 and UV absorber can produce a synergistic effect and give the substrate more comprehensive protection.
In the application of automotive coatings, the use of Xinyue XY-UV123 and UV absorbers UV-384, UV-1130, UV-928 or UV-400 can significantly improve the weather resistance of the coating and effectively prevent gloss loss, cracking, and color change. , bubbles and delamination. In two-pack systems, Light stabilizers can be used in primers and topcoats.
In the application of wood coatings, Xinyue XY-UV123 combined with UV absorber UV-384 or UV-1130 has a good protective effect on air-drying alkyd paints. Light stabilizer blends can be added to film-forming and decorative paints.
Recommended dosage (relative to resin solids):
Automotive and Industrial Paints:
0.5-2.0% Xinyue XY-UV123 + 1.0-3.0% UV-1130 or UV-384 or UV-928 or UV-400
Decorative paint and wood paint:
0-5-2.0% Xinyue XY-UV123 (used alone) or + 1.0-3.0% UV-1130 or UV-384 Xinyue XY-UV123 to achieve the best amount of the best effect should be selected according to the experimental results.
