For Polymer production andPoly(meth)acrylics: Perodox K80 may be used for various polymerization reactions. It can be used in emulsion, solution and bulk polymerizations. In emulsion processes, Perodox K80 may be activated by organic-soluble or water-soluble reducing agents, or by metal compounds to achieve polymerization at room temperature or lower.
When no accelerators are used, effective polymerization can be obtained in the temperature range of 50-200°C. For example, styrene and methyl methacrylate can
be polymerized in bulk in the temperature range of 60-100°C using Perodox K80. Perodox K80 may also be used for emulsion polymerization of various vinyl monomers. In this case it may be used in combination with reducing agents to achieve reproducible results at low temperatures. For Thermoset: CHP may be used as an
initiator for the room temperature cure of promoted unsaturated polyester and vinyl ester resins, and elevated temperature cure of non-promoted resins.

Organic peroxides are thermallyunstable substances which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition may occur with a substance in the packaging as used for transport is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.

SADT 60°C

Method The Heat Accumulation Storage Test is a recognized test method forthe determinationof the SADT of organic peroxides (see Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria - United Nations, New York and Geneva).

Due to the relatively unstablenature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Do Sender Chem recommends a maximum storage temperature.

Ts Max. 25°C

Note When stored under the recommended storage conditions, Perodox K80 will remain within the Do Sender Chemspecifications for a period of at least 9 months after delivery.

Packed in plastic drums withspecifications of 1000kg, 200kg, and 25kg. Perodox K80 is classified as Organic peroxide type F; liquid, Division 5.2; UN 3109
