| Freezing poin (ºC | Concentrated antifreeze Si-OAT-I |
| EG(kg/ Ton ) | 500 |
| AC7050(kg/ Ton ) | 500 |
The production process:
(1) Add AC7050 to the EG solution at room temperature mix and stir for 20-30 minutes;
(2) Add a certain amount of water to the freezing point;
(3) Test the freezing point, boiling point, pH value, foam tendency and other items of the product; This product meets the VW TL 774-G standard.
(4) The finished product of engine coolant with good corrosion inhibition can be obtained by filtering and filling.
The water based on all additives follow the standard ofASTM D3306
