Product Description
Trigonox K-90
Trigonox K-90 may be used as curing agent for unsaturated polyester resins
Product Description
Trigonox K-90 StorageDue 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, Nouryon recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.
Ts max.: 40°C and Ts min.: -30°C to prevent crystallization
NOTE:When stored under these recommended storage conditions, Trigonox K-90 will remain within the Nouryon specifications for a period of at least 3months after delivery.
Trigonox K-90 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 SelfAccelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.
SADT: 70°C
Method:
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, NewYork and Geneva).
Trigonox K-90 Safety and handlingKeep containers tightly closed. Store and handle Trigonox K-90 in a dry well-ventilated place away from sources of heat
or ignition and direct sunlight. Never weigh out in the storage room. Avoid contact with reducing agents (e. g. amines),
acids, alkalis and heavy metal compounds (e. g. accelerators, driers and metal soaps). Please refer to the Safety Data
Sheet (SDS) for further information on the safe storage, use and handling of Trigonox K-90. This information should be
thoroughly reviewed prior to acceptance of this product. Trigonox K-90 Major decomposition productsAcetophenone, 2-Phenylisopropanol, Methane
Dosage | Depending on working conditions, the following peroxide and accelerator dosage levels are recommended: |
TRIGONOX K-90 | 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-90 | 90°C |
Gel times at 20°C | 1.5 phr Trigonox K-80 + 0.5 phr Acc. NL-51P | 1230 min |
The following table indicates the performance of Trigonox K-90, in comparison with usual ButanoxÒ systems, in a vinylester resin: |
Vinylester resin | 100 | 100 |
Trigonox K-90 | 1.8 | - |
Trigonox LPT | - | 2 |
Accelerator NL-49P | - | 2 |
Accelerator NL63-10P | - | 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-90 | 1.8 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 |

Application
For Polymer production and Poly(meth)acrylics: Trigonox K-90 may be used for various polymerization reactions. It can
be used in emulsion, solution and bulk polymerizations. In emulsion processes, Trigonox K-90 may be activated by
organic-soluble or water-soluble reducing agents, or by metal compounds to achieve polymerization at room temperature
or lower. When no accelerators are used, effective polymerization can be obtained in the temperature range of 50-200°C.
For example, styrene and methyl methacrylate can be polymerized in bulk in the temperature range of 60-100°C using
Trigonox K-90. Trigonox K-90 may also be used for emulsion polymerization of various vinyl monomers. In this case
Trigonox K-90 may be used in combination with reducing agents to achieve reproducible results at low temperatures. For
Thermoset: Trigonox K-90 may be used as an initiator for the room temperature cure of promoted unsaturated polyester
and vinyl ester resins, and elevated temperature cure of non-promoted resins.
