Properties:

PESA is an environmentally friendly multi-scale scale corrosion inhibitor with non-phosphorus and non-nitrogen.

PESA has good scale inhibition and dispersibility for calcium carbonate, calcium sulfate, barium sulfate, calcium fluoride and silicon scale in water, and its effect is superior to ordinary organic phosphine scale inhibitor. Compound with phosphonate, PESA has a good synergistic effect.

PESA has a certain role in corrosion inhibition, it is also a multi-scale inhibitor.

PESA has a good biodegradable performance, and widely used in a range of fields, especially for the cooling water system in high alkali, high hardness and high pH conditions. It can be operated under high concentration index.

PESA has a good intermiscibility with chlorine compatibility, and has a good compatibility with other chemicals.
