Product Overview:
Trigonox® V388 is a versatile methyl ethyl ketone peroxide (MEKP) designed for the curing of unsaturated polyester resins, particularly when used in conjunction with a cobalt accelerator at both room and elevated temperatures. This product, identified by CAS number 1338-23-4 and EINECS/ELINCS No. 215-661-2, is listed on the TSCA inventory, ensuring compliance with regulatory standards.
Applications:
Trigonox® V388 serves as a general-purpose MEKP for curing unsaturated polyester resins. The combination of Trigonox® V388 and a cobalt accelerator is ideal for general GRP (Glass Reinforced Plastics) and non-GRP applications, such as laminating resins and castings. Its reliability has been demonstrated over many years. For marine applications, it is recommended to use Butanox® M-50 due to its low water content and absence of polar compounds, preventing osmosis and related issues.
Key Specifications:
Appearance: Clear, colorless liquid
Total Active Oxygen: 9.8-10.0%
Physical Characteristics:
Density at 20°C: 1.120 g/cm³
Flashpoint: 37°C (Closed Cup) / ≥ 63°C (Open Cup)
Thermal Stability:
Organic peroxides, including Trigonox® V388, are thermally unstable and can undergo self-accelerating decomposition. The Self-Accelerating Decomposition Temperature (SADT) for Trigonox® V388 is 55°C, determined using the Heat Accumulation Storage Test, a recognized method for assessing the thermal stability of organic peroxides.
Storage Guidelines:
To maintain quality, store Trigonox® V388 at a maximum temperature of 25°C. Under these conditions, the product remains within Nouryon specifications for at least six months post-delivery.
Packaging and Transport:
Trigonox® V388 is typically packaged in a 30-liter HDPE can (Nourytainer®) containing 20 kg of peroxide solution. Packaging and transport comply with international regulations, classified as Organic peroxide type D; liquid; Division 5.2; UN 3105; PG II.
Safety and Handling:
Store and handle Trigonox® V388 in a dry, well-ventilated area, away from heat, ignition sources, and direct sunlight. Avoid contact with reducing agents, acids, alkalis, and heavy metal compounds. Refer to the Safety Data Sheet (SDS) available at nouryon.com/sds-search for detailed safety and handling information.
