Mode of action:

POLYDOSIL 20 is a blend of steam-volatile, aliphatic, alkalizing polyamines and alkaline dispersing polymers.

The surface-active polyamines support the formation of a thin, homogeneous magnetite protective layer and stabilize its structure. Contact between the metal surface and the electrolyte is prevented without affecting heat transfer. Due to the distribution coefficient of the alkalizing active ingredients, the entire system incl. Steam and condensate network alkalized and effective protection against corrosion and deposit formation achieved.

Existing corrosion products and deposits are gently dispersed and broken down. Heat transfer is improved throughout the plant, which, in combination with POLYDOSIL 20, results in significant savings in water, energy and chemical costs.

Environmental sustainability:

POLYDOSIL 20 has been evaluated by medical and hygienic institutes as ecologically and toxicologically safe and is biodegradable.

Further information can be obtained from the EU safety data sheet.

Application/ Dosage:

POLYDOSIL 20 is added to the boiler feed water as a concentrated or diluted solution without any further additives. The quantity to be used depends on the water quality and the condition of the plant and is determined accordingly by the technical advisor.

The detection of POLYDOSIL 20 in the system is carried out either by a simple rapid test or a photometric test.

Delivery terms:

The product is supplied in liquid form in containers of 30, 60 or 210 liters.

The product must be stored frost-free in closed containers. The shelf life is 2 years.
