appliance

Trigonox V388 is a general purpose methyl ethyl ketone peroxide (MEKP) for curing unsaturated polyester resins in the presence of a cobalt accelerator at room or elevated temperatures. It is particularly suitable for the production of reinforced or non-reinforced articles such as laminating resins and casting resins. MEKP with low water content and free of polar compounds, such as Butanox M-50, is recommended for use in shipbuilding.

At room temperature, Trigonox V388 needs to be used with a cobalt accelerator (such as Accelerator NL-49P) to achieve optimal curing results.

thermal stability

Self-accelerating decomposition temperature (SADT)Temperature: 55°C
Test Methods: Heat accumulation storage test, see Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria – United Nations.

stockpile

Due to the relative instability of organic peroxides, storage temperature should not exceed 25°C. When stored under the recommended conditions, Trigonox V388 remains within product specifications for at least 6 months after delivery.

Packaging and transportation

Standard Packaging: 20 kg peroxide solution in 30 liter HDPE (Nourytainer®) barrel
Transport Classification: Organic peroxide, Class D; Liquid, Class 5.2; UN 3105, PG II

Security and handling

Keep the container tightly closed, store and operate in a dry, well-ventilated place, away from heat or ignition sources, avoid direct sunlight. Avoid contact with reducing agents, acids, alkalis and heavy metal compounds (such as accelerators, desiccants and metal soaps).
