XP 85 ORGANIC SURFACTANT
Typical chemical and physical properties XP 85 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 2,4,6-Tri-(6-aminocaproic acid)-1,3,5-triazine CAS No. 80584-91-4
Appearance White granules or powder
Average composition 85 % active material, 15 % water
Molecular weight 468.6
the chlorine content (ppm) ≤340
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
- 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 85 may be used for corrosion inhibition of multi-metal systems.
- This inhibitory effect can be improved by a combination with XP 42 which is a water-soluble metal deactivator
- No tendency to form nitrosamines
Guidelines for use
XP 85 contains water; it must not be stored below freezing point or in a warm environment; it also must not be heated. X is a free acid having a limited solubility in water. To dissolve XP 85 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.
