E703A Surfactant. It is a non-phosphorus and strong alkali resistant surfactant specifically used for electrolytic oil removing and degreasing. It is a high-quality surfactant produced by applying foreign polyether surfactants and additives and the latest techniques. It can be used to prepare various high-quality cleaning products like electrolytic oil removing powder and degreasing agent, for electrolytic oil removing and degreasing of steel workpieces with the help of conventional cleaning additives. It has the following advantages:

        High-performance--powerful capability for electrolytic oil removing and degreaisng of various stubborn greasy dirt, high efficiency, good emulsifying capability and good durability; resist to strong alkali and electrolytic solution, have small amount of foam or moderate amount of foam. Good wetting, penetrating, emulsifying, dispersing and cleaning properties;

        Using temperature--used at the temperature scope from 50 to 90℃；

        Meet the technical requirements of various electrolytic oil removing and degreasing production lines of various workpieces on surfactants.

Appearance                           light-colored or yellow oily liquid

Water solubility                     soluble with water at room temperature

pH value                                5～9(5% water solution)  

Cloud point                           90℃±10℃（1%E703A water solution) 

Cleaning efficiency              ≥99%  (bath solution: 0.5%E703A、2%Na2CO3 water solution; 70℃±2℃，artificial greasy dirt)

Electrolytic oil removing powder: 2%～8%(choose according to whether the greasy dirt of the workpiece to be cleaned to be light or heavy)

Electrolytic degreasing agent: 2%～8%(according to whether the greasy dirt of the workpiece to be cleaned to be light or heavy)

Immersing and ultrasonic oil removing powder: 3%～15%(according to whether the greasy dirt of the workpiece to be cleaned to be light or heavy)

Immersing and ultrasonic degreasing agent: 3%～15% (according to whether the greasy dirt of the workpiece to be cleaned to be light or heavy)

Appearance                           visual inspection

Water solubility                     E703A is soluble with water at room temperature

pH value                                measure with pH meter (5% water solution)  

Cloud point                           (1%E703A water solution)   prepare 1%E703A water solution and take 50ml and drop it into 50ml colorimetric tube, then heat it in the water bath kettle until it becomes turbid, take out the colormetric tube and cool it in the air, use 0～100℃ microthermometer to the temperature of this 1%E703A water solution when it changes from being turbid to being transparent and make a record. The temperature thus measured is its cloud point.

Cleaning efficiency              measure according to Chapter Six of JB/T 4323.2-1999

(Bath solution: 0.5%E703A、2%Na2CO3 water solution; 70℃±2℃，artificial greasy dirt)
