Description:

GLACELF AUTO SUPRA is a “very long life” antifreeze based on high purity monoethylene glycol and organic corrosion inhibitors.

GLACELF AUTO SUPRA antifreeze, when mixed with an appropriate quantity of water, becomes a coolant fluid recommended for all internal combustion engines in cars and vans, trucks, construction machinery and agricultural tractors.

In accordance with French Decree No. 95-326 of 20th March 1995 concerning the distribution of certain substances containing monoethylene glycol, GLACELF AUTO SUPRA contains a bittering agent to give it a bitter taste as a guarantee against accidental ingestion by children or users.

In our range of antifreezes, GLACELF AUTO SUPRA is the top-of-the-range product.

Applications:

• Dilution in demineralised or softened water

GLACELF AUTO SUPRA is diluted in demineralised water (< 8°F) to form a permanent coolant that can be used throughout the year.

To obtain a coolant perfectly mixed, it is recommended to mix mechanically the antifreeze with the water.

Protection against freezing depends upon the proportions of GLACELF AUTO SUPRA in the water.

• Longer life 

GLACELF AUTO SUPRA is entirely safe to use in all cast iron or aluminium engines and in cooling systems containing aluminium or copper alloy radiators. 

Advantages:

• Very long-term protection against metals corrosion

Excellent protection against corrosion, erosion, and cavitation, for aluminium water pumps.

Heat transfer remains optimised: fully organic additives allow avoiding any formation of deposits and leave surfaces clean. 

• No formation of deposits leave surfaces clean 

The additives in GLACELF AUTO SUPRA give to the coolant:

• Chemical neutrality (pH 7-8.5),

• A reserve of alkalinity to neutralise the acids resulting from the combustion gases,

• Resistance to foaming (mainly instability of the foam that might form)

• Compatibility with hard water (maximum 40°F). 

• High temperature protection of aluminium 

GLACELF AUTO SUPRA contains no silicates, phosphates, chromates, nitrites or boron.

The coolant fluids obtained by diluting GLACELF AUTO SUPRA are also inert to elastomeric seals and paints.
