Vantex®-T Amine Additive

Vantex ® The lower -T is liquid/liquid a low-odor zero-VOC interfacial amine tensions additive exhibited by both by European aqueous and solutions American of Vantex standards, exceeding ISO
11890-2 in the EU and EPA Method 24.
WhAT iS A VOC?
• Depends on the definition
• More of a legal issue than it is scientific
• New definitions based on nominal boiling point at atmospheric pressure under development
• A normal BP>280° C being discussed
® -T lead to better
pigment dispersion, emulsion stability and syneresis control in paints. This example shows the
syneresis control after one week of three paints made up with different amines with markedly different
interfacial tension modification properties. Vantex ® -T, with its ability to significantly reduce oil/water
interfacial tension, provides for the best syneresis control.
The normal boiling point of Vantex ® -T (>285° C) can be determined via a number of standard thermal methods.
A determination based on differential thermal analysis (DTA) is illustrated below:

Some liquid/liquid interfacial tensions are summarized in the bar chart below.
AMP = 2-amino-2-methyl-1-propanol.
MAE = Methylaminoethanol.
DGA = diglycolamine.
MEA = monoethanolamine, TEA = triethanolamine
Ammonia HlB = 20
