INITIA® 611 is a differentiated phosphinocarboxylic acid (PCA) dispersant for use in a wide range of applications. INITIA® 611 is differentiated from traditional PCA polymers in that it is optimized with a higher level of phosphino functional groups. These phosphino functional groups are the basis for improved efficacy and thermal stability versus more basic polyacrylic acids. INITIA® 611 is an exceptional inhibitor for calcium carbonate, calcium sulfate and barium sulfate scales. Additionally, INITIA® 611 is a highly effective dispersant and deposit control agent in boiler applications up to 500psi. INITIA® 611 meets the criteria of 21 CFR 173.310 for boiler applications where steam may contact food and is Kosher Certified.

INITIA® 611 is an effective tool for use in boiler applications for iron transport, hydroxyapatite control, and general solids dispersion. INITIA® 611 was evaluated using Thermogravimetric analysis (TGA) to demonstrate the thermal stability of the polymer. Figure 1 shows that INITIA® 611 substantially retains its integrity up to 240°C which equates to about 500 psi in boiler applications. Additionally, INITIA® 611 was compared to a traditional PCA using Differential Scanning Calorimetry (DSC.) DSC is a thermal analysis tool that measures heat changes (exotherms) that occur to the polymer during a controlled increase in temperature. The DSC analysis depicted in Figure 2 shows that INITIA® 611 and the traditional PCA are virtually identical in their exothermic responses to increasing temperature with significant events occurring between ~210°C and 240°C for both polymers.

calcium carbonate and calcium sulfate inhibition
INITIA® 611 was evaluated versus traditional PCA using a modified NACE calcium carbonate test method (Figure 3) and the standard NACE method for calcium sulfate (Figure 4) inhibition. In both evaluations INITIA® 611 demonstrated comparative or better to the competitive PCA.
