Product features:
1. It has strong dispersing effect on carbonates, etc., has high thermal stability, can be used under severe conditions such as high temperature of 300 °C, and has good compatibility and synergistic effect with other water treatment agents. It has a good inhibitory effect on the formation of scale including phosphate.
2. Excellent anti-scaling performance and high temperature resistance, widely used in low-pressure boilers, central heating, central air conditioning and various types of circulating cooling water systems.
