Product Function: Corrosion inhibitor
Chemical Type: Acyl amido carboxylic acid
Chemical nature: 6-((1-Oxomethyloctyl)amino)hexanoic acid

Hostacor IS is a low foaming corrosion inhibitor mainly used in cutting & grinding fluids, in rolling emulsions and water-based hydraulic fluids (HFA-E, HFA-S).

Hostacor IS is a solid product and comes in acid form, offering the formulator full flexibility for neutralization. 
Water-soluble salts of Hostacor IS are obtained by neutralization with alkanolamines and aqueous alkali hydroxides. 
These are used either alone or in combination with other water-soluble corrosion inhibitors or lubricants.

Alkanolamines salts derived from Hostacor IS are excellent corrosion inhibitors for steel and show very good hard water stability. 
Hostacor IS is compatible with phosphoric acid esters in neutralized form, like Hordaphos MDB. 
Thus extreme-pressure properties of semi and full synthetic formulations based on Hostacor IS can be adjusted.

Benefits
•Excellent corrosion protection of steel
•Reduces copper and cobalt leaching
•Low foaming
•Hard-water stable
•Boron free
•Free of secondary amines
•Comes in acid form; offers full flexibility for neutralization
•Broad registration status

Application
Water-soluble salts of Hostacor IS are obtained by neutralization with alkanolamines and aqueous alkali hydroxides. 
These are used either alone or in combination with other water-soluble corrosion inhibitors or lubricants in cutting and grinding fluids and in aqueous hydraulic systems.
The preferred application of the water-soluble salts is machining of ferrous metals. 
The addition of suitable inhibitors is recommended for the machining of non-ferrous metals and aluminum.
The neutralization with Genamin CH 020 is recommended to minimize cobalt leaching, or to prevent the formation of white rust on zinc coated iron.
Alkanolamine salts derived from Hostacor® IS are excellent corrosion inhibitors and show very good hard water stability.
Hostacor IS is absolutely compatible with phosphoric acid esters in neutralized form, like Hordaphos MDB. 
Thus, EP-properties of semi and fully synthetic formulations based on Hostacor IS can be adjusted.

To improve lubrication and to minimize foaming, the combination with EO/PO-mix polymers like Genapol B, Genapol PN 30 or Genapol PS is recommended.
Suitable mixing ratio:
10 – 50 % Genapol B, Genapol PN 30 or Genapol PS
90 – 50 % Hostacor IS (after neutralization)

Hostacor IS is a solid product, showing a melting range of about 50°C. 
Due to the process conditions, it contains approx. 10 % of water, which is homogeneous associated in the solid state. 
During storage and/or transportation at elevated temperatures Hostacor IS tends to liquify and the associated water can separate on the product surface.
This water separation is typical of the product and has no negative impact on its performance.
In case of separation, Hostacor IS has to be homogenized at 60 - 70°C prior to use.
Maximum storage time: 2 years
