Recommended Applications

Copolymerization of styrene/butadiene (SBR rubber) and acryl nitrile/ butadiene/styrene (ABS rubber): The emulsion polymerization can be initiated through a redox mechanism at low temperatures. Suitable reducing agents are Fe-salts, sulphites, dithionites, etc. Temperature range: 5 to 20°C Dosing: 0,1 to 0,3 phr

Polymerization of (meth-)acrylates and acrylic resins dispersions: The emulsion polymerization can be initiated through a redox mechanism at low temperatures. Suitable reducing agents are Fe-salts, sulphites, dithionites, ascorbinic acid or sugar, etc. Temperature range: 50 to 80°C Dosing: 0,1 to 0,5 phr

Product Handling and Storage
  • Maximum storage temperature (Ts max) : 30°C
  • Minimum storage temperature (Ts min) : 0°C
  • Storage stability as from date of delivery : 6 months
  • Keep packaging tightly closed in a well ventilated place at indicated storage temperature. Keep away from reducing agents e.g. amines, acids, alkalis, heavy metal compounds (e.g. accelerators, driers, metal soaps). Never weigh out in storage room. Oxidizing agent. Decomposes violently under the influence of heat or by contact with reducing agent. Never mix with accelerators. Organic Peroxides are more or less stable products but will decompose under the influence of heat. To minimize a loss of quality during storage, it is important that the recommended maximum storage temperature is not exceeded. If a minimum storage temperature is given, an undesirable process such as a solidification or phase separation, is known to occur below this temperature.
