| Dosage | Depending on working conditions, the following peroxide and accelerator dosage levels are recommended: | |||
| Trigonox K-80 | 1 - 3 phr | |||
| Accelerator VN-2 | 0.5 - 3 phr | |||
| Accelerator NL-51P | 0.1 - 0.5 phr | |||
| * phr = parts per hundred resin | ||||
| Cure Characteristics in pure UP resin | In a high reactive standard orthophthalic resin the following characteristics were determined: | |||
| Activation temperature | 1 phr Trigonox K-80 | 90°C | ||
| Gel times at 20°C | 1.5 phr Trigonox K-80 + 0.5 phr Acc. NL-51P | 1380 min | ||
| The following table indicates the performance of Trigonox K-80, in comparison with usual ButanoxÒ systems, in a vinylester resin: | ||||
| Vinylester resin | 100 | 100 | ||
| Trigonox K-80 | 2 | - | ||
| Trigonox K-80 | - | 2 | ||
| Accelerator NL-49P | - | 2 | ||
| Accelerator NL-49P | - | 2 | ||
| Accelerator VN-2 | 1 | - | ||
| Gel time at 20°C (min.) | 12 | 17 | ||
| Cure at 20°C in 2 mm laminate | Time to achieve a Barcol hardness (934- 1) of 25-30 in hours | 0.5 | 1 | |
| Residual styrene (%) | ||||
| after 24 hours | 4.8 | 7.1 | ||
| after 1 month | 0.6 | 4.2 | ||
| Cure Characteristics at elevated temperatures | The fact that processing times of several hours can be achieved with low cobalt dosages makes Trigonox K-80 very suitable for use in e.g.filament winding techniques. Simulating the manufacture of a pipe at 50°C consisting of a laminate of 10 mm with a glass content of 30% and an epoxy vinylester resin gave the following results: | |||
| Trigonox K-80 | 2 phr | |||
| Accelerator NL-49P | 0.25 phr | |||
| Gel time at 20°C | 330 minutes | |||
| Curing data at 50°C | Gel time | 62 minutes | ||
| Time to Peak | 118 minutes | |||
| Peak exotherm | 117 °C | |||
| Barcol hardness (934- 1) 10 minutes after reaching the peak: 50 | ||||
