Applications
Eka® SC (sodium chlorate) is essential to environmentally compatible paper pulp bleaching. It is the functional ingredientin the generation of chlorine dioxide, which, in turn, is the main component in ECF (Elemental Chlorine-Free) bleaching.
Up to 95 percent of all sodium chlorate produced worldwide is consumed by the pulp industry. Its second most common
use is by the chemical industry where it is used as a precursor in the production of sodium and ammonium perchlorate
and sodium chlorite. Sodium chlorate and sodium chlorite are the common precursors to chlorine dioxide, which is usedin many water treatment applications. Other common industrial applications for sodium chlorate include as an oxidant in
the mining industry for the extraction of uranium and vanadium; in the automotive industry as a surface treatment formetals; it is also used in the Printed Circuit Board industry for the control and replenishment of the cupric chloride
etchant. This versatile chemical is utilized in many devices that require an oxygen source (e.g. breathing apparatus).

Packaging and transport
Depending on the customer set-up, Eka® SC is shipped in bulk tank, drums or in supersacks. Eka® SC is classified ashazardous material and consequently transportation and packaging design must adhere to the all applicabletransportation regulations. Transportation may take place by road, railway, air or sea. Each mode of transport demands
specific regulations with special requirements regarding packaging, vehicle and documentation.

IISafety and handling
Please refer to the current SDS (Safety Data Sheet) for preventive protection and first aid response. Eka® SC is classified as
dangerous goods. It is a strong oxidizing agent and is very soluble in water. Crystal sodium chlorate is stable attemperatures up to 250°C (482°F). Above this temperature chlorate decomposes and oxygen is liberated. Be aware that
sodium chlorate in liquid form is a hazard as well. Sodium chlorate solution is a clear odorless liquid that may become
invisible when it dries on any organic material like cloth, leather, paper or wood. All that is required is a spark, minor
friction or heat, to ignite. Sodium chlorate in its pure form is not flammable; however, due to the fact it releases oxygen
during decomposition, it will act as an extreme combustion accelerant in the presence of flammable materials. Additional
information on the handling of Eka® SC is available in the Sodium Chlorate Product Information Manual that can beobtained from your Nouryon representative.

Mandatory protective equipment
Because sodium chlorate should never come in contact with organic materials like cloth and leather; make sure, as aminimum, all personnel handling Eka® SC are provided with, and required to wear, the following items:
Measure 1

A protective suit (preferred anti-flammable treated) made of vinyl, neoprene, orPVC

Measure 2

A pair of vinyl or neoprene boots

Measure 3

Protective goggles that fit snugly over the eyes

Measure 4

Vinyl or neoprene gloves

Measure 5

A hard-hat with a full-face shield
