Tribasic Carboxylic Acid Metalworking Fluid Water Corrosion Inhibitor CAS 80584-91-4

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.
