Application

Trilon B (tetrasodium salt of ethylenediaminetetraacetic acid) (2-aqueous disodium ethylene diamine-N, N, N', N'-tetraacetic acid chelate III, helaton III, Na-EDTA, Na-EDTA) is a white crystalline powder or white crystals, very soluble in water, very slightly soluble in alcohol.

Trilon B is used for heat and power, washing equipment, pipes, boilers, water boilers, and heating systems, and in the production of household chemicals and detergents, as a stabilizer in the polymerization processes, the pulp and paper industry in the production of rubber, in analytical chemistry and in many other areas.

Safety requirements

May cause irritation of the skin, mucous membranes of the eyes and respiratory tract.

Packing

Trilon B packed in the following consumer packaging: glass jars with a ground stopper, glass jars with screw cap made of polymeric material, packs of unpainted plastic film, bags of unpainted plastic film bag inside of a thin polymer film.

Then into a shipping container in used barrels, drums, bags, boxes.

Guaranteed shelf life

3 years from date of manufacture.
