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). | |||||||||||||
