Overview
Carbosperse™ K-700 water treatment polymers are deposit control agents sold to water treatment service companies for use as formulation components for water treatment (e.g., cooling, boiler) programs. The Carbosperse K-700 polymers are multi-functional anionic polyelectrolytes that disperse particulates (e.g., silt, clay, iron oxide, pigments), and inhibit scale formation (e.g., calcium carbonate, calcium sulfate, calcium oxalate, barium sulfate, calcium phosphate, calcium phosphonate) over a broad pH range, and sequester di- and trivalent cations (e.g., calcium, magnesium, iron, copper, chromium, zinc). Used around the world, Carbosperse K-700 polymers have earned a reputation for high quality, consistency, stability, formulating flexibility, high total and active solids, and narrow molecular weight distributions. The Carbosperse K-700 polymers include solvent and water polymerized polyacrylates, polymethacrylates, acrylate copolymers, and acrylate terpolymers and their function(s) as deposit control agents are shown in the table below.
