Teclub Anti Freeze - Coolant BS6580

car care   antifreeze

BS 6580 Coolant is an economical coolant concentrate providing frost and corrosion protection. In addition it prevents boiling and overheating of your engine. Exempt from potentially harmful additives such as nitrites, amines and phosphates, the coolant also contributes to a safer environment. For the perfect operation of water-cooled internal combustion engines, the engine and cooling system have to be adequately protected from corrosion and frost damage. To that purpose a coolant is added to the cooling water.

BS 6580 Coolant offers the following benefits to the user:
Corrosion protection, also for non-ferrous metals
Frost protection
Boiling protection
Seal compatibility
Hard water stability
Low cost

BS 6580 Coolant provides year-round frost and corrosion protection. It is recommended to use at least 33 volume % of BS 6580 Coolant in the coolant solution. This provides frost protection up to -18°C. Concentrations higher than 70 volume % are not recommended; maximum frost protection (about -69°C) is obtained at a concentration of 68 volume %.

BS 6580 Coolant is conformable to British Standard BS6580:1992.
The product should be stored at ambient temperatures and periods of exposure to temperatures above 35°C should be minimized. As with any antifreeze coolant, the use of galvanised steel is not recommended for pipes or any other part of the storage/mixing installation. TOXICITY & SAFETY
For Toxicity and Safety Data we refer to the Material Safety Data Sheet. The transport is not regulated. Labeling as for any MEG based coolant is required: Xn: R 22 (Harmful if swallowed) and S 2 (Keep out of reach of children). This product should NOT be used to protect the inside of drinking water systems against freezing.
