PA-L1 surface modifier
Ⅰ、 Performance characterics
This product is a surface modifier of colloidal  titanium salt, it has many characteristics  such as strong adjustable capacity, bath solution with long-term stability, the process by controlled conveniently, especially the strong capacity of resistance to hard water. It can accelerate the speed of phosphating film forming, reduce the phosphate sediment and  form more meticulous close-grained and more uniform phosphating film coating, which makes coating  more smooth, plump burnish, beautiful and have stronger resistance to corrosion and adhesion.     
PA-L1 is more suitable for hard water and make surface better.
 
Ⅱ、Preparation
It prepared with many chemical fertilizers such as Colloidal titanium salt, phosphate, emulsifying agent, anti-hard water agent .

Ⅳ、Test method
Remove good working solution 10ML to the conical flask, add 2-3 drops of bromophenol blue indicator and then titrate with 0.1N sulfuric acid. It is the end when the color turns from red to colorless, and the total number of milliliters consumpted 0.1N sulfuric acid is total alkalinity.     
Ⅴ、Usage method
ⅰ、Bath preparation
  First put PA-L1 surface regulators into water until all dissolved, then stir with water adding, and it can be used after the determination of total alkalinity and pH.
 ⅱ、Bath Management
If Phosphating fluid worked normally but Phosphating workpiece appeared hanging ash, back to yellow, rust and other phenomena, which indicated that the solution was polluted seriously and should drain out and replace it with new fluid.     
Ⅵ、Package and storage
ⅰ、25KG plastic bags.
ⅱ、Stored for one year in dry warehouse.
