Trigonox V328 Methyl Ethyl Ketone Peroxide, in Solvent Mixture
Product Description
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.
For Trigonox V328
Ts max. = 25°C
When stored under the recommended storage conditions, Trigonox V328 remain within the Nouryon specifications for a period of
at least six months after delivery.
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 V328 SADT : 50°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).
TrigonoxV328 Packaging and transport
Both packaging and transport meet the international regulations.

Trigonox® V328 is a methyl ethyl ketone peroxide (MEKP) for the cure of unsaturated polyester resins in the presence of a cobalt accelerator at ambient and elevated temperatures.The curing system Trigonox® V328/cobalt accelerator is developed for general purpose GRP- and non GRP-applications. Examples: the curing of laminating resins and castings.Practical experience throughout
many years has proven that for marine applications a special MEKP with low water content and without polar components is demanded in order to prevent from osmosis and other problems. Butanox M-50 is the MEKP preferred and advised for these kind of applications.For room temperature application it is necessary to use Trigonox® V328 together with a cobalt accelerator (e.g. Accelerator NL-49P) to obtain a proper reactivity.
