AMPEROX M50

Description:
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, We recommend a maximum storage temperature (T, max.) for each organic peroxide product.
For AMPEROX M50 T, max. = 25°C. When stored under the recommended storage conditions, AMPEROX M50 will remain within our specifications for a period of at least three months after delivery.

APPLICATIONS

  • AMPEROX M50 is a 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 AMPEROX M50 with cobalt accelerator is particularly suitable for the curing of gelcoat resins, laminating resins, lacquers and castings, moreover the manufacture of light resistant parts may be possible contrary to the curing system benzoyl peroxide/amine accelerator
  • Practical experience throughout many years has proven that by the guaranteed low water content and the absence of polar compounds in AMPEROX M50, this peroxide is very suitable in GRP products for e.g. marine applications.
  • For room temperature application it is necessary to use together with a cobalt accelerator (e.g Accelerator 6).
    M50 Depending on working conditions, the following peroxide and accelerator dosage levels are recommended:

Safety and handling

  • Keep containers tightly closed. Store and handle AMPEROX M50 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).

Dosing

  • Depending on working conditions, the following peroxide and accelerator dosage levels are recommended:
  • AMPEROX M50 : 1-4 phr
  • Accelerator 6 : 0.5-3 phr

Major decomposition products

  • Carbon dioxide, Water, Acetic acid, Formic acid, Propanoic acid, Methyl ethyl ketone

Packaging and transport

  • The standard packaging is a 30 KG HDPE can for peroxide solution.
    In Asia Pacific the standard packaging is a 30 | HDPE can for 20 kg peroxide solution.
    Both packaging and transport meet the international regulations. 
  • For the availability of other packed quantities contact our representative.
    AMPEROX M50 is classified as Organic peroxide type  D; liquid; Division 5.2; UN 3105: PG II.

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 AMPEROX M50
  • SADT: 60°C
  • The Heat Accumulation Storage Test is a recognized test method for the determination of the SADT of organic peroxides.
