Application
ANTIOXIDNT HONOX-1425 has low volatility, high resistance to extraction and good
compatibility with most substrates. It is a highly efficient and non discolouring
stabilizer for organic substrates. It is particularly useful as a stabilizer and
esterification catalyst in modified rosin resins and in PET and other
thermoplastic polyesters. It is also effective for the stabilization of polyolefin
(particularly polypropylene fiber), crosslinked elastomer and special adhesive,
wax, oil etc. It shows good processing stability during polypropylene fiber
production when combined with antioxidant 168.
