unsaturated polyester resins catalyst acetylacetone peroxide 37187-22-7
Trigonox 44B is an acetyl acetone peroxide formulation for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures.
With the curing system Trigonox 44B/cobalt accelerator a much faster speed of cure may be achieved than with curing systems based on a MEKP plus cobalt accelerator, at room and elevated temperatures.
Normally the gel times with Trigonox 44B are comparable to those with Butanox® M-50.
Trigonox 44B is particularly suitable in those applications where a fast mould-turnover is required, e.g. for the cold press moulding or resin injection moulding techniques.
The system Trigonox 44B/cobalt accelerator will give a higher peak exotherm than a standard MEKP/cobalt accelerator system. Due to this fact, is it recommendable to avoid the production of too thick laminates in one operation. At low temperatures a reasonable speed of cure is still obtained when Trigonox 44B is used in combination with large amounts of cobalt accelerator possibly in combination with Accelerator NL-63-100 (N,N-Dimethylaniline) as promotor.

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 44B |
|
Ts max. = 25°C |
||
|
|
|
|
|
|
Ts min. = -10°C to prevent crystallization |
|
|
When stored under the recommended storage conditions, Trigonox 44B |
||||
|
|
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 44B |
|
SADT : 60°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). |
