Applications

Lotnox 245 is a sterically hindered phenolic antioxidant that protects organic substrates against  thermo-oxidative degradation during manufacturing, processing, and end use.

Lotnox 245 is effective in styrene polymers, particularly impact-modified polystyrenes, ABS, MBS,  SB, and SBR-latices, as well as in POM homo- and co-polymers. It is also very useful for the  stabilization of polyurethanes, polyamides, thermoplastic polyesters, PVC, and other polymers. In  addition to imparting thermostability to the finished polymer, it is effective as a chain stopper during  PVC polymerization.

Lotnox 245 can be used in combination with other additives such as co-stabilizers (e.g. thioesters,  phosphites, phosphonites), light stabilizers, and other functional stabilizers. The effectiveness of  Irganox® 245 with Irgafos® 168 is particularly noteworthy.

Lotnox 245 is recommended for applications such as: 

• Hot-melt adhesives 

• Sealants 

• Solvent-based coatings
