| | TINUVIN 571 Usage And Synthesis |
| Description | Tinuvin 571 is a liquid benzotriazole UV absorber. Imparts good light stability to a variety of polymers. Features high compatibility in various substrates, low volatility even at elevated temperatures, and high absorption and protection efficiency. Highly soluble in many solvents, monomers, or intermediates and easily emulsifiable in water-based adhesives. | | Uses | UV 571 has good thermal stability and compatibility with various polymers. It is widely used in thermoplastic PUR, paints and foams, also used for PPVC, PVB, PMMA, PVDC, EVOH, EVA, thermosetting unsaturated resins, PA, PET, PUR webs and PP fiber.Tinuvin 571 is also suitable for latex, waxes, adhesives, homogeneous polystyrene and its copolymers, elastomers, and polyolefins. | | benefits | Tinuvin 571 is highly soluble in many solvents, monomers, or intermediates
and easily emulsifiable in water-based adhesives. It can be considered for
use during polymerization as well as for topical applications on PVC sheets.
Tinuvin 571 features high compatibility in various substrates, low volatility
even at elevated temperatures, and high absorption and protection
efficiency. |
