Catalyst for Unsaturated Polyester Resin /Curing Agent MEKP
Trigonox V388 is general purpose methyl ethyl ketone Peroxide (MEKP) for the curing of unsaturated polyester resins in the presence of a cobalt Accelerator at room and elevated temperatures.
The curing system Trigonox V388/cobalt accelerator is developed for general purpose GRP- and non GRP-applications such as the curing of laminating resins and castings.
Practical experience throughout many years has proven that for marine applications a special MEKP with low water content and without polar compounds is demanded in order to prevent from osmosis and other problems. Butanox® M-50 is the MEKP advised for this application.
For room temperature application it is necessary to use Trigonox V388 together with a cobalt accelerator (e.g. Accelerator NL-49P).

| 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 V388 | Ts max. = 25°C |
|
|
| Ts min. = -10°C |
|
| When stored under the recommended storage conditions, Trigonox V388 | |
|
| 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 V388 | SADT : 55°C |
