XP 65                 ORGANIC SURFACTANT

Typical chemical and physical properties XP 65 plus, an organic polycarboxylic acid, is a water-soluble corrosion inhibitor which can be classified as an amphoterics organic surfactant.

It is an inhibitor for all types of water based lubricants and functional fluids.

MF: C21H36N6O6     CAS No. 80584-91-4

Appearance White granules or powder

Average composition 65 % active content, 35 % water

Molecular weight 468.6

the chlorine content (ppm) ≤250

Recommend treat level 0.2-1.5%

(1) If the PH is adjusted with triethanolamine (TEA) or another base to pH > 8 then the solubility in water increases to > 5.0%

 (2) TEA > 99% pure is recommended to meet requirement of German TRGS 611.

Applications and typical treat levels              

All types of water based lubricant and functional fluids: 

- metal working fluids (semi-synthetic and synthetic) 

- high water based hydraulic fluids (HFC) engine coolants 

- engine and other cooling systems

Benefits   

  - 30% more active than XP 65

  - Improved product consistency

  - Does not form resinous films or gums on metals

  - Offers an extremely low foaming tendency and an excellent air release 

  - Good biodegradability

  - Compatible with hard water 

   - XP 65 may be used for corrosion inhibition of multi-metal systems. 

   - This inhibitory effect can be improved by a combination with XP 42 a water-soluble metal deactivator

   - No tendency to form nitrosamines   

Guidelines for use

XP 65 contains water; it must not be stored below freezing point or in a warm environment; it also must not be heated. XP 65 is a free acid having a limited solubility in water. To dissolve XP 65  in  water  take  the  solid  product  and  then  slowly  add, triethanolamine, or another neutralisation agent, drop-wise with constant stirring until the pH reaches 8.5 (measure the pH with a pH meter). The solution will be clear within a short time.
