Doverphos S-9228 Bis (2,4-dicumylphenyl) pentaerythritol diphosphite 154862-43-8 ICC Industries-Dover Antioxidant >> Phosphite Heat stabilizer >> Phosphite Acrylic/Acrylate Resins Amide Resins Polyurethane Vinyl Coatings >> Powder Coatings Coil Coating Powder coating Doverphos® S-9228 is a patented, free-flowing solid phosphite antioxidant developed by Dover Chemical Corporation. its high molecular weight, low volatility, and high phosphorous content. Doverphos® S-9228 offers: Superior thermal stability and low volatility under extended high temperature conditions Excellent atmospheric and in-polymer hydrolytic stability Outstanding processing protection against discoloration and thermal degradation Doverphos® S-9228 provides excellent color and melt flow stability when used in high density polyethylene. Doverphos® S-9228 has extremely good hydrolytic stability when exposed to accelerated humid aging conditions (Figure 4). Doverphos S-9228's high molecular weight, low volatility and high phosphorous content provide superior thermal stability, giving you outstanding processing protection against discoloration and thermal degradation. Extremely good hydrolytic stability prevents the formation of black specs and keeps blends uniform. Used as an antioxidant in paints and coatings. Antioxidants can be added to powder and coil coating formulations to prevent discoloration and loss of physical properties. Free-flowing solid phosphite secondary antioxidant. Used in powder and coil coating formulations. Possesses high molecular weight, low volatility and high phosphorous content. Provides superior thermal stability under extended high temperature conditions, very good atmospheric and in-polymer hydrolytic stability, outstanding processing protection against discoloration and thermal degradation and very good color and melt flow stability.
