Phosphonobutane Tricarboxylic Acid (PBTC), also called 1,2,4-Butanetricarboxylic acid, 2-phosphono-; 2-Phosphono-1,2,4-butanetricarboxylic acid is a clear colourless to light yellow liquid.
It is a very effective scale inhibitor used in various industrial applications. Due to its higher performance properties it is a very cost-effective inhibitor compared to standard Phosphonates such as HEDP/ATMP. This is mainly due to superior stability to chlorine, bleach and bromine. In cooling water PBTC performs well at high PH or temperatures. It further shows high effectiveness in high alkaline solutions such as industrial cleaners.
Widely used in industry for applications in industrial water treatment and industrial cleaning such as:
