Potassium Persulfate
Description
Potassium persulfate is a white, crystalline, odorless salt. It is used as initiator for the polymerization of monomers and as a strong oxidizing agent in many applications. It has the particular advantage of being almost non-hygroscopic, of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.

Applications
Potassium Persulfate is a suitable initiator for emulsion or solution polymerization of acrylic monomers, vinyl acetate, vinyl chloride etc.and for emulsion copolymerization of styrene, acrylonitrile, butadiene etc. It is also a kind of oxidizing agent, used in cleaning and pickling of metal surface, accelerated curing of low formaldehyde adhesives and modification of starch, production of binders and coating materials, also can be used as desizing agent and bleach activator. It is an essential component of bleaching formulations for hair cosmetics.
Storage and Handing
Storage
• Store in a cool, well-ventilated area away from all source of ignition and out of direct sunlight. Store in a dry location away from heat. Store at temperature less than 30 o C.
• Keep away from incompatible materials. Keep containers tightly closed. Do not store in unlabeled or mislabeled containers
• Protect from moisture. Do not store near combustible materials. Keep containers well sealed, seal only with original vent cap. Ensure pressure relier and adequate ventilation.
• Store separately from organics and reducing materials. Avoid contamination which may lead to decomposition.
Handing
• Avoid contact with eyes, skin and clothing. Use with adequate ventilation.
• Do not swallow. Avoid breathing vapors. Mists or dust. Do not eat, drink or smoke in work area.
• Prevent contact with combustible or organic materials.
• Label containers and keep them tightly closed when not in use.
• Wash thoroughly after handing.
First-aid Measures
• Inhalation— Remove affected person to fresh air. Do not use mouth to mouth resuscitation. Seek medical attention if effects persist.
• Eye---Flush eyes with running water for at least 15 minutes with eyelids held open. Seek specialist advice.
• Skin contact---Wash affected skin with soap and mild detergent and large amounts of water.
• Ingestion---Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Do not mouth-to-mouth resuscitation. Seek medical service immediately.
