Proveedor de agente de cura rápida de Hardner
Trigonox K-90 se puede usar como agente de curado para poliéster insaturado resinas.
Sin la adición de un acelerador, la polimerización comienza solo por encima de la temperatura de activación de 90 ° C. Para la cura a temperatura menor, Trigonox K-90 debe acelerarse por cobalto o vanadio. Juntos con Aceleradores de cobalto El tiempo de gel a temperatura ambiente es muy largo y, por lo tanto, es particularmente adecuado para aquellas aplicaciones donde se requiere un largo tiempo de producción, por ejemplo, en la producción de grandes partes y en el devanado de filamentos. Los tiempos de gel y cura suficientemente rápidos solo se obtienen por encima de 35 ° C.
Junto con los aceleradores de vanadio, Trigonox K- 90 da un tiempo de gel corto y una cura rápida a temperatura ambiente. Esto se puede mejorar aún más agregando un promotor especial, como el ácido piruvico. Con tal sistema, es posible obtener una cura rápida de las resinas UP, incluso a baja temperatura. También para resinas como la resina Vinylester, estas combinaciones son muy adecuadas.

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). |
