Light yellow liquid Triazine UV Absorber , tinuvin 571 light
benzotriazole uv absorber
UV571 is a liquid benzotriazole type ultraviolet absorbers which
imparts good light stability to a variety of polymers during its
Name : UV571
Chemical name : 2 - ( 2H - Benzothiazol - 2 - yl ) - 6 - ( dodecyl
) - 4 - methylphenol
CAS No. 23328 - 53 - 2 / 125304 - 04 - 3 / 104487 - 30 - 1
Features: The liquid UV absorber UV571 is highly soluble in many
solvents , monomers , or intermediates and easily emulsifiable in
water-based adhesives. I t can be considered for use during
polymerization as well as for typical applications on sheets ( PVC
, PC) .
UV571 features high compatibility in various substances , low
volatility even at elevated temperatures , and high absorption and
protection efficiency without imparting any yellowness to the
UV571 can be applied in thermoplastic PUR, coating and integral
foams, rigid and plasticized PVC, PVB, PMMA, PC, PVDC, EVOH, EVA,
hot cured unsaturated polyesters, non-staining formulations for PA
fibers and spin finishes for PA, PET, PUR, and PP fibers. The
product is also suitable for lattices, waxes, adhesives, styrene
homo- and copolymers, elastomers and polyolefins.
