Light Stabilizer 770 J1601 Good light stability BASF's light stabilizer TINUVIN 770/DF has a wide range of applications
Tinuvin® 770 is a low molecular weight hindered amine light stabilizer specifically formulated to protect the surface of thicker PP materials from photo-damage. It offers broad compatibility and easy dispersion. Unlike UV absorbers, Tinuvin®770 does not depend on polymer thickness. Therefore, it provides excellent light stability even for items with high specific surface areas, such as films and tapes.

Features
BASF TINUVIN 770/DF is a low molecular weight hindered amine light stabilizer (HALS) with broad applicability and ease of use, allowing incorporation into polymers via standard methods. BASF 770 exhibits excellent thermal stability and, due to its non-absorption of visible light, does not affect polymer color. BASF TINUVIN 770 can be used synergistically with light stabilizer B75 or UV absorber series such as Tinuvin 326 to provide excellent light stability for plastics.
Unlike UV absorbers, BASF TINUVIN 770/DF light stabilizer's efficacy remains unaffected by plastic thickness, making it particularly suitable for applications like flat belts and films. It also delivers high light stability for thick plastic components. Its performance surpasses that of UV light stabilizers. When combined with antioxidants, it enhances heat resistance; when paired with UV absorbers, it produces synergistic effects, improving light resistance. Sulfur-containing stabilizers like thiobis(propionic acid esters) and sulfur-containing phenolic antioxidants may affect 770's performance, requiring caution during compounding. The reference dosage is 0.1%-1%, with specific amounts determined based on customer requirements.
Application
BASF's light stabilizer TINUVIN 770/DF offers broad applicability and superior performance compared to UV light stabilizers and nickel-containing stabilizers. It is suitable for plastics requiring excellent light stability, such as polypropylene, high-density polyolefins, EPDM, polystyrene, high-impact polystyrene, ABS, SAN, ASA, and polyurethanes. It is also highly effective for polyamides and polyacetals.
To achieve the high efficacy of BASF Light Stabilizer 770, adequate base stabilization of the plastic is essential to prevent thermal-oxidative degradation damage. For finished products requiring high light stability, the influence of pigments is also significant; pilot testing is recommended.
