TRIGONOX C
Trigonox C is a monofunctional peroxide, the chemical name is tert-butyl peroxybenzoate, and it is an aromatic peroxide used for high temperature curing of Unsaturated Polyester resins.
Trigonox C is preferentially used for thermocompression molding of unsaturated polyester resins (SMC, BMC, etc.) within the temperature range of 120-170°C.
Trigonox C can also be used in combination with highly active peroxide as co-accelerator for pultrusion processes in the range of 100-150 °C.

Applications
Trigonox C can be used for the market segments: polymer production, polymer crosslinking, thermoset composites and acrylics production with their different applications/functions.
Trigonox C, tert-butyl peroxybenzoate, is an aromatic perester, which is used for the curing of unsaturated polyester resins at elevated temperatures.
Trigonox C is preferred for the curing of UP resin based Hot Press Moulding formulations (SMC, BMC etc.) in the temperature range of 120-170°C.
Trigonox C can also be used in combination with high reactive peroxides as kicker in formulations for pultrusion in the temperature range of 100-150°C.
Trigonox C is used for the crosslinking of natural and synthetic rubbers, as well as thermoplastic polyolefins.
Rubber compounds containing Trigonox C have moderate processing safety in combination with a very high rate of cure.
Safe processing temperature (rheometer ts2 > 20 minutes): 100°C.
Typical crosslink temperature (rheometer t90 about 12 minutes): 140°C.
Trigonox C is not recommended for compounds which contain carbon black.
Trigonox C may be used for the (co)polymerization of styrene in the temperature range of 100-140°C.
In practice, combinations of two or more peroxides with diverging activities are used to reduce the residual monomer content in the final polymer and to increase reactor efficiency.
Trigonox C is also an efficient initiator for the ethylene polymerization at high pressure in both autoclave and tubular processes.
To obtain a wide spectrum of polymerization temperatures, Trigonox C is often used in combination with other peroxides.
Depending on reaction conditions, Trigonox C is active in the temperature range of 220-270°C.
In the temperature range of 100-170°C, Trigonox C can be used as an initiator for the solution polymerization or copolymerization of acrylate and methacrylate, especially for the production of coatings.
Trigonox C can also be used as initiator for bulk and suspension polymerization or copolymerization of acrylate and methacrylate.
Trigonox C is used for the cross-linking of natural and synthetic rubbers, as well as thermoplastic polyolefins.
Being thermally unstable substances, it may undergo self accelerating decomposition.
Trigonox C is used in wire and cable applications.
Thermal stability
Organic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition.
The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the SelfAccelerating Decomposition Temperature (SADT).
The SADT is determined on the basis of the Heat Accumulation Storage Test.
SADT 60°C (140°F)
Half-life data
The reactivity of an organic peroxide is usually given by its half-life (t½) at various temperatures.
For Trigonox C in chlorobenzene half-life at other temperatures can be calculated by using the equations and constants mentioned below:
0.1 hr: at 142°C (288°F)
1 hr: at 122°C (252°F)
10 hr: at 103°C (217°F)
Formula 1: kd = A·e-Ea/RT
Formula 2: t½ = (ln2)/kd
Ea: 151.59 kJ/mole
A: 2.23E+16 s-1
R: 8.3142 J/mole·K
T: (273.15+°C) K
Storage
Due to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time.
To minimize the loss of quality, it is recommended that a maximum storage temperature (Ts max. ) for each organic peroxide product.
Ts Max. : 25°C (77°F)
Ts Min. : 10°C (50°F)
Safety and handling
Keep containers tightly closed.
Store and handle Trigonox C in a dry well-ventilated place away from sources of heat or ignition and direct sunlight.
Never weigh out in the storage room.
Avoid contact with reducing agents (e. g. amines), acids, alkalis and heavy metal compounds (e. g. accelerators, driers and metal soaps).
