Is moisture sensitive. Reduce gas fading and inhibits discoloration due to NOx. It gives high contribution to thermal yellowing reduction during processing and long term heat stability. shows high thermal stability and high solubility in polymeric materials as well as broad compatibility in coating polymers. SONGNOX® CS PQ is highly recommended especially for the applications where polymers and/or binders are cured at elevated temperature and need thermo-stabilization, e.g. powder coatings, coil coatings and specific solvent borne coatings (eg. automotive). It is listed on DSL, IECSC, ENCS, NZIOC, ECL, TSCA and PICCS inventories.
