CAS No .  31570 - 04 – 4 Phosphite Antioxidant irgafos 168 for PE / PC

Quick Detail :

ANTIOXIDANT168 is a trisarylphosphite processing stabiliser . It is a highly effective , low - volatile and hydrolysis resistant antioxidant for coating resins . It protects the resin polymer against oxidation during resin synthesis , manufacturing of the paint , processing ( thermal curing and overbaking ) and the designed life - time of the final coating . ANTIOXIDANT168 provides excellent protection against discolouration and change of physical properties caused by excessive heat exposure .

Name : ANTIOXIDANT 168

CAS No . : 31570 - 04 - 4

Chemical name : THIODIPROPIonIC ACID DISTEARYL ESTER
Use:stabilize polyesters , polycarbonates , polyamides , polystyrene , and elastomers . Use levels can range from 0 . 10 to 0 . 80 % based on the polymer .

Applications :

ANTIOXIDANT 168 provides outstanding thermal and colour stability to a variety of coating resins upon exposure to high temperatures during synthesis and subsequent processing . It is particularly suited to stabilise alkyd and polyester resin based coating systems that are used in applications such as

•  industrial powder coatings ( electrical and gas oven heating )

•  coil coatings

•  other industrial high bake coatings

A special feature of the ANTIOXIDANT 168 phosphite stabiliser is its efficiency in presence of NOx gases and thus its potential to function in critical gas oven curing conditions .

In electrical ovens and gas fired ovens where the coated substrates being exposed to only very low NOx concentrations , a combination ANTIOXIDANT168 with hindered phenolic antioxidants such as ANTIOXIDANT1076 or ANTIOXIDANT1010 typically leads to a synergistic performance improvement . In this case phenol - free synergistic antioxidant systems can be obtained by using ANTIOXIDANT 168 in combination with hindered amine light stabilisers ( HALS ) such aUV292 or UV622 .

The amount of ANTIOXIDANT168 required for optimum performance should be determined in trials covering a concentration range .
