Scale. Sludge. Sediment. Sand. Silt. Soil. The ene­mies of cooling, scrubbing and boiler systems. Now you can check them before they destroy the effi­ciency of your system.

When you add formulations containing Good-rite® K-700 polyacrylic acid polymers to your process water, you can prevent the formation of various types of scale including calcium carbonate, calcium sulfate and calcium phosphate.

Formulations with Good-rite® K-700 polymers pre­vent the formation of phosphate sludge. And they act as dispersants to keep silt, sand, mud and bio­logical matter in suspension.

Classed as anionic polyelectrolytes, four of the Good-rite® K-700 polymers are available in water solutions as straight acids; two as sodium salts in powder form. Their molecular weights range from 1800 to 90,000.
