Description

With a higher binding capacity, NTA chelates
more metal ions with less material than
EDTA chelating agents. With a nearly 50 percent
higher chelation value (154 vs. 104), NTA is
pound-for-pound more effective than common
EDTA chelating agents, like Versene 100,
Dissolvine E-39 and Trilon B. In fact, you need
only 0.68 pounds of NTA to replace one pound
of EDTA – without sacrificing performance.

STABLE, WATER-SOLUBLE COMPLEXES
NTA forms water-soluble complexes with
polyvalent metal ions, including calcium,
magnesium, iron, copper and zinc.
These complexes are stable at temperatures up
to 100°C and a pH range between 2.0 and 13.5,
particularly in alkaline conditions.

EFFECTIVE IN SURFACE CLEANING
NTA is effective in caustic-based formulations
for a number of surface cleaning applications
including hard surfaces, metals, and vehicles.
- Extensive testing in our laboratories has shown
that NTA-based vehicle wash formulations are
effective against a variety of soiling conditions.
- In addition, our tests found no corrosion on
the paint and lacquer finishes, and no attack
on the rubber components.
