Trigonox K-90 may be used as curing agent for unsaturated polyester resins.
Without the addition of an accelerator the polymerization starts only above the activation temperature of 90°C. For the cure at lower temperature Trigonox K-90 must be accelerated by cobalt or vanadium. Together with cobalt accelerators the gel time at room temperature is very long and is therefore particularly suitable for those applications where a long production time is required, for instance in the production of large parts and in filament winding. Sufficiently fast gel and cure times are only obtained above 35°C.
Together with vanadium accelerators Trigonox K- 90 gives a short gel time and a fast cure at room temperature. This can be improved further by adding a special promotor, like pyruvic acid. With such a system it is possible to get a fast cure of UP resins, even at low temperature. Also for resins like vinylester resin, these combinations are very suitable.

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, |
|||||||||||||
|
|
AkzoNobel recommends a maximum storage temperature (Ts max.) for |
|||||||||||||
|
|
each organic peroxide product. |
|
||||||||||||
|
|
For Trigonox K-90 |
Ts max. = 40°C and |
||||||||||||
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Ts min. = -30°C to prevent crystallization |
|
|
|
When stored under these recommended storage conditions, Trigonox K-90 |
|||||||||||||
|
|
will remain within the AkzoNobel specifications for a period of at least 3 |
|||||||||||||
|
|
months after delivery. |
|
|

|
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 K-90 |
SADT : 70°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). |
