Quent® 770

Bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate. Acts as a hindered amine light stabilizer (HALS) of N-H type that protects polymers from degradation due to ultraviolet radiation and long term heat aging. Can be used in combination with phenolic & phosphite antioxidants, higher molecular weight HALS, and UVA’s to optimize performance in outdoor use. Effectively used in PP, PE, ethylene-propylene copolymer and terpolymer, polyurethane, ABS, PS, HIPS, SAN and PVC. Used alone or in combination with higher molecular weight HALS for the UV stabilization of both thick and thin cross section articles including tapes, films, automotive parts, and lawn furniture.

Hansen Solubility Parameters

[16.6, 2.6, 2.2]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Quent® 770. A practical determination of these HSP values would provide higher certainty. Learn More.
