*Test conditions for lubricity [SRV method]: Lubricity (coefficient of friction) evaluation using an oscillating friction and wear test (SRV tester) 
Test specimen: Steel ball (SUJ-2, Φ 10 mm), steel disk (SUJ-2)  
Test conditions: Load 100 N (50 → 500 N), frequency 50 Hz, vibration width 1.0 mm, temperature 40°C 

Water solubility of "EXCEBIOL"

Water solubility evaluation of "EXCEBIOL" 

"EXEBIOL" can be easily mixed with water and maintained in a homogeneous state by mixing with water and shaking. 

<Test Method> 
"EXCEBIOL" water solubility evaluation test 
A two-layer sample was prepared by weighing 2mL of each part of "EXCEBIOL" in a test tube and gently adding 2 ml of water. 
 (For "EXCEBIOL DE-1000," 3mL of water was added to 1g of sample.) 

 The sample was first shaken gently and then gradually and vigorously to check its compatibility with water. 
 The compatibility of the samples with water was confirmed by shaking the samples gently and then gradually more vigorously.  [The photographs in the table above show the appearance before shaking and after 24 hours of standing.]  

Comparison test 
 The ester/mineral oil/PAO base oil was operated in the same way except that each oil was added to water, and it was confirmed that the oil separated from the water over time.
