Features of Coolant Fluid
It is suitable for producing long life engine coolant, and has excellent corrosion Inhibition for all kinds of metal of engine cooling system.
In particular, it has a good protective effect on aluminum alloy, which can effectively prevent the corrosion of aluminum pump cavitations and heat transfer corrosion of aluminum alloy surface.
Good storage stability, the freezing point of both T1033 and T1035 are below -25.0, Stable storage at room temperature.
Prevent scale deposit, avoid reducing radiator cooling effect, prolong engine cooling system service life.

Operation Method of Cooling Fluid Production
Put ethylene glycol into agitated vessel accordingly. Stir and add additive T1033 and additive T1035 accordingly. Then stir 20min. Put deionizer water into agitated vessel. Then stir 10min. Test PH ( Like, the PH is 8.0-9.0 on -35℃cooling liquid). Test freezing point. After it is qualified, add into defoaming agent and pigment.
Concentrate Production
Put ethylene glycol into agitated vessel accordingly. Stir and add additive T1033 and additive T1035 accordingly. Then stir 20min. Test PH (Like, the PH is 8.0-9.0 on -35℃cooling liquid). Test freezing point. After it is qualified, add into defoaming agent and pigment.
