Antifreeze ANF 40 is a full concentrate radiator protection based on Monoethylene glycol for operation in summer and winter, with frost and rust protection effect (all-year operation).

Antifreeze ANF 40, the high-performance corrosion antifreeze protection for motors and cooling systems meets the modern demands of the development in motor construction. It is free of nitrites, amines, and phosphates.

Characteristics

• Protection against corrosion for all parts of the cooling system made of the materials steel, gray iron, aluminium, copper, brass, soft solder. 
• Avoidance of cavitation damages, such as on the coolant pump 
• Compatibility with varnishes 
• Compatibility with hose and sealing materials 
• Avoidance of sediments, which can cause radiator plugging 
• Avoidance of foaming

Applications:

• Antifreeze ANF 40 is because of its specially used additives excellently suitable for aluminium, light alloy and gray iron motors (please observe manufacturer´s service instructions)
• Recommended working concentration 50 % Antifreeze ANF 40 and 50% water, by which a radiator protection up to about -38 °C can be achieved. Antifreeze protection down to -69°C is possible with a maximum of 68% Antifreeze ANF 40 and 32% water
• Depending on the type and the manufacturer´s instructions the contents of the cooling system shall be replaced every 2 to 3 years
