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). | ||||
