Nouryon 21S Peroxide

Product Description
 
Nouryon 21S 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,Nouryon
recommends a maximum storage temperature (Ts max.) for each organic peroxide product.

For Trigonox 21S :Ts max.= 20°C and
                             Ts min. = -30°C to prevent crystallization

When stored according to these recommended storage conditions, Trigonox 21S will remain within the Nouryon

specifications for a period of at least 3 months after delivery.
 
Nouryon 21S 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 Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.

For Trigonox 21S       SADT:35°C .
                                  Emergency temperature (Tem): 25°C
                                  Control temperature (Tc): 20°C

The Heat Accumulation Storage Test is a recognized test method for the determination of the SADT of organic peroxides (see Recommendations on the Transport of Dangerous Goods,Manual of Tests and Criteria - United Nations, New York and Geneva).


 
Nouryon 21S Safety and handling
Keep containers tightly closed. Store and handle Trigonox21S 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).

Please refer to the Material Safety Data Sheet (MSDS) for further information on the safe storage, use and handling of Trigonox 21S. This information should be thoroughly reviewed prior to acceptance of this product.

Nouryon 21S Packaging and transport
In North America Trigonox 21S is packed in non-returnable, vented, five gallon polyethylene containers of 35 lb net weight.

In other regions the standard packaging is a 30-liter HDPE can (Nourytainer), vented, for 25 kg peroxide content.

Both packaging and transport meet the international regulations. For the availability of other packed quantities consult your 
Nouryon representative.

Trigonox 21S is classified as Organic peroxide type C; liquid, temperature controlled, Division 5.2; UN 3113; PG II.

Application

Trigonox 21S, tert- butyI peroxy -2-ethylhexanoate, is a perester which is used for the curing of unsaturated polyester resin at elevated and high temperatures.

Trigonox 21S is preferred for the curing of UP resin based Hot Press Moulding formulation (such as SMC and BMC) in the temperature range of 120 - 160°C. As Trigonox 21S is a high reactive peroxide, it is very suitable as a kicker in formulations for pultrusion and SMC/BMC.

In combination with a cobalt accelerator, Trigonox 21S is also applicable for the cure of UP resins in the temperature range of 60°C and higher. Application area can be air drying lacquers, diplacquers, wall panels, filament winding, etc.

Trigonox 21S has normally a much shorter pot life in the pure resin than Trigonox C, tert-butyl peroxybenzoate.
