Star brite Blue Non-Toxic Anti-freeze is a ready-to-use anti-freeze for boat fresh water system and engine cooling water systems providing cold weather burst protection down to -73°C (-100°F).
It contains corrosion inhibitors to help protect against rust and corrosion of aluminium, copper, solder and brass. This non-toxic antifreeze will also not harm rubber or other hoses and gaskets.
Star brite Non-Toxic Blue Antifreeze can be used in engine cooling systems during the winter by draining the coolant system and refilling with Star brite Non-Toxic Blue Antifreeze. When the engine is recommissioned and put back into service it is best to drain the antifreeze again and replace it with the manufacturers recommended coolant.
This non-toxic antifreeze can also be used in direct cooled engines when laying up.
Star brite Non-Toxic Blue Antifreeze is safe for use in drinking water systems during the winter, however, it is not safe to consume and must be drained from the system before drinking the water again.
In the spring when you wish to use the water system again for drinking or washing make sure you flush the system through for at least 20 minutes with fresh water until all the coloured antifreeze has disappeared, then refill the tank with fresh water.
Star brite -73°C Burst Protection Non-Toxic Anti-Freeze provides up to -73°C based on a copper pipe filled with this anti-freeze. A PVC pipe filled with this anti-freeze is likely to burst at -62°C. If temperatures are likely to drop below minus 73°C then it is recommended to use an anti-freeze designed to protect against harsher conditions.
Star brite Non-Toxic Blue Antifreeze can be used neat or diluted, however, diluting the antifreeze reduces the effectiveness of the antifreeze.
