Technical specifications
FIPRO MAT 457 is a liquid based on non-toxic glycols and organic corrosion inhibitors. The product is used as a heat transfer fluid for solar panels, for heat pumps, as a filling fluid in air conditioning systems, for cold water circuits, etc.
. FIPRO MAT 457 lowers the freezing point of aqueous solutions and can therefore be used for water conditioning in installations exposed to frost.
Usage and Applications
The use of FIPRO MAT 457 makes it possible to:
Avoid bacterial degradation of glycol and consequent formation of glycolic acid corrosive to circuits
Maintain dispersion of material originating from any deposits
Block corrosive phenomena regardless of the oxygen content in the circuit
Protect metals in contact (steel, aluminium, copper)
. Easily biodegradable product (OECD 3011) and free of nitrites, amines, molybdates, phosphates

DOSAGE AND APPLICATION
The dosage of FIPRO MAT 457 depends on the temperature drop required:
% vol 10 20 30 40 50 60
°C -3 -7 -12 -20 -32 -43
Because of its complete and rapid miscibility in water, FIPRO MAT 457 can be introduced into the circuit as it is, then adding water until the desired concentration is reached. However, it is preferable to first prepare a solution with water and then add it to the circuit.
The optimal dosage and analytical control limits should be defined with the help of Fiprokim Technical Service.
The residual concentration of FIPRO MAT 457 in the circuit can be assessed by measuring the density of the solution:
% vol 10 20 60
Density (20°C 1,007 1,018 1,025 1,033 1,040 1,043

PACKAGING AND STORAGE
FIPRO MAT 457 should be stored in a cool place out of direct sunlight; if stored under the recommended conditions, it has a stability of more than one year.
SECURITY
Please read the warnings on the Product Safety Data Sheet before use. FIPRO MAT 457 is not classified as dangerous in accordance with EEC Directives 67/548, 2001/59 and 99/45 on the classification, packaging and labelling of dangerous substances; it is also not classified under category 4 of GHS (Globally Harmonized System) Regulation EC N°A 1272/2008.
