Product Description

catalyst for unsaturated polyester resin /curing agent MEKP

Trigonox V388 is general purpose methyl ethyl ketone peroxide (MEKP) for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures.

The curing system Trigonox V388/cobalt accelerator is developed for general purpose GRP- and non GRP-applications such as 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 compounds is demanded in order to prevent from osmosis and other problems. Butanox^® M-50 is the MEKP advised for this application.

For room temperature application it is necessary to use Trigonox V388 together with a cobalt accelerator (e.g. Accelerator NL-49P).

Storage	Due 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,
	AkzoNobel recommends a maximum storage temperature (T_s max.) for
	each organic peroxide product.
	For Trigonox V388	T_s max. = 25°C
		T_s min. = -10°C
	When stored under the recommended storage conditions, Trigonox V388
	will remain within the AkzoNobel specifications for a period of at least 3
	months after delivery.
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 Self-Accelerating Decomposition Temperature (SADT). The
	SADT is determined on the basis of the Heat Accumulation Storage Test.
	For Trigonox V388	SADT : 55°C
