ACUMER is a low molecular weight polyacrylate with a selected molecular weight around 2000 to optimize the anti-scale performance through at least three mechanisms: • Solubility enhancement by threshold effect, which reduces precipitation of low solubility inorganic salts (calcium carbonate in particular). • Crystal modification, which deforms the growing inorganic salt crystal to give small, irregular, readily fractured crystals that do not adhere well to surfaces and can be easily removed during cleaning operations. • Dispersing activity, which prevents precipitated crystals or other inorganic particules from agglomerating and depositing on surfaces.
