Trigonox K-90 kann als Aushärtungsmittel für ungesättigter Polyester verwendet werden Harze.
Ohne die Zugabe eines Beschleunigers beginnt die Polymerisation nur über der Aktivierungstemperatur von 90 ° C. Für die Heilung bei niedrigerer Temperatur muss Trigonox K-90 durch Kobalt oder Vanadium beschleunigt werden. Zusammen mit Kobaltbeschleuniger Die Gelzeit bei Raumtemperatur ist sehr lang und ist daher besonders für Anwendungen geeignet, bei denen eine lange Produktionszeit erforderlich ist, beispielsweise bei der Herstellung großer Teile und bei der Filamentwicklung. Ausreichend schnelles Gel und Heilungszeiten werden nur über 35 ° C erhalten.
Zusammen mit Vanadium Acceleratoren bietet Trigonox K -90 eine kurze Gelzeit und eine schnelle Heilung bei Raumtemperatur. Dies kann durch Hinzufügen eines speziellen Promotors wie Pyruvinsäure weiter verbessert werden. Bei einem solchen System ist es möglich, eine schnelle Heilung von Upharzen zu erhalten, selbst bei niedrigen Temperaturen. Auch für Harze wie Vinylesterharz sind diese Kombinationen sehr geeignet.

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). |
