OUR BUSINESS
The presence of metal ions, even in traces, is enough to alter the physical and chemical properties of a product or process. For exemple the presence of copper or iron for instance, act as oxidation cataysts on fats and oils (rancidification); traces of heavy metals will also reduce the effectiveness of bleaching agents. Water used in appliances suchs as: heat exchangers or evaporators causes problems due to the effect of calcium and magnesium that act as precipitant agents on the metal surfaces and thus lead to a loss of effectiveness and life shortening the apparatus.
To solve these problems DABEER has developed the DABEERSEN range of products. These products chelate agents are molecules containing the amino and carboxylic groups. The principal characteristics of aminocarboxylic derivatives are as follows:
- Stable a high temperatures.
- Soluble in water.
- Hydrolitic stability in an acid and alkaline conditions.
- Inert to most chemical and bacterial agents.
- Forms stable chelates with most metallic ions in a wide range of pH and temperatures.

“Chelate” is derived from the Greek “CHELE” meaning crab or lobster claw. In these complexes the metal atom is trapped in the structure of the compound by various atoms of the chelate or sequestering agent and from which they are difficulty released by other substances (fig.1). |
