Solubility:Easy to dissolve in organic solvents such as toluene.

1.It has a good synergistic effect with other hindered amine light stabilizers, especially high molecular weight hindered amine light stabilizers (such as 944, 119) and benzoate UV absorbers (such as UV328).

2.In products based on polyolefin, the color stability, light retention, and durability of the products are excellent.

3.Compared to other small molecular weight hindered amine light stabilizers, it has good compatibility and solubility with polyolefins.

UV-3853 is a hindered amine light stabilizer mainly used as a UV light stabilizer for thermoplastic polymer materials such as polyacetal, acrylonitrile butadiene styrene copolymer(ABS), and styrene acrylonitrile copolymer(SAN), engineering plastics such as polyethylene(PE), polypropylene(PP), polyamide(PA), acrylonitrile styrene acrylic acid copolymer(ASA), and impact resistant polystyrene(HIPS), as well as thermoplastic polyolefin elastomers(TPO) and polyurethane(PU). UV-3853 is widely used in fibers, films, sheets, pipes, tapes, molding, and other materials made of these materials. In addition, UV-3853 is also an antioxidant additive for ash free lubricants.

Store in a cool and dry ventilation place, and keep away from sparks, heat sources, strong oxidizing agents, and strong reducing agents.
