Properties and Applications:

• Thermoset Composites: Perkadox® 16 is a solid peroxydicarbonate used primarily for curing unsaturated polyester and methacrylic resins at temperatures of 60°C and higher. Perkadox® 16 is not suitable for the production of clear castings or coatings as it can lead to cloudy final products. For transparent products it is recommended to use Perkadox® 16S . Perkadox® 16 exhibits high reactivity at elevated temperatures due to the low activation temperature of Perkadox® 16 as well as its long service life at room temperature.Perkadox® 16 is usually combined with less reactive peroxides such asTrigonox CTrigonox 29-B50. Trigonox 21S maybePerkadox® GB-50XUse together to ensure good curing. Ideal for applications where long gel times or production times are required at room temperature and fast curing at 60-140°C. Examples: pultrusion molding, fiber winding, artificial marble production, etc.
• Polymer Production: Polymerization of Vinyl Chloride: Perkadox® 16 can be used for suspension and intrinsic polymerization of Vinyl Chloride at temperatures in the range of 40-65°C. It can also be used as a polymerization agent for the polymerization of vinyl chloride. Perkadox® 16 can be used alone or in combination with other peroxides such as 1,1,3,3-tetramethylbutyl peroxyneodecanoate (Trigonox 423), isopropylphenyl peroxyneodecanoate (Trigonox 99) or peroxydilauroyl (Laurox) are used in tandem to increase reactor efficiency.
• Acrylic Resin Production: Perkadox® 16 is an initiator for the (co-)polymerization of methacrylates and acrylates.

Half-life and thermal stability:

• The half-life of Perkadox 16 in chlorobenzene was 0.1 h (82°C), 1 h (64°C) and 10 h (48°C) at different temperatures.
• Thermally unstable with a self-accelerating decomposition temperature (SADT) of 40°C.
• Maximum storage temperature is 20°C.

Packaging and transportation:

• The standard packaging is 20kg carton, in compliance with international regulations.
