Dear Saravanan,

Where is the sediment?
* at the bottle (container) of anti rust oil?
* or at the bottom of the surface area after it was sprayed?

Mostly the additive for anti rust protection are POLAR additive. This POLAR additive will protecting the metal surface area after sprayed. But the POLAR additie will not dilute properly to the oil (media) which is NON-POLAR.

So the sellection of additive is important.

My advise, just check the blending date. better if you get a product which not more than 6 months from blending date.

regards,


Nurudin
Thanks you immediate reply
This oil Antirust oil type, the viscosity as 1.0 - 1.5 cSt. Application as after finished the job dipping process only.
And my analysis as the separate the settled material and take IR spectra. It peaks related to barium sulfonate and sorbitan mono oleate.

Regards
Saravanan

Dear Nurudin

Its settled in bottom of the container. When we blend it happen within twenty four hours. i am check the additive, it manufactured before one year.

Look at anti rust, as you look at paint. Paint typically has a polymer/wax and the solvent/turpentine or similar are the carriers for the polymer.

Typically, after painting, the solvent component evaporates, leaving the polymer/TiO2/ZnO2 as the coating.

Antirust oil would probably have a solvent component acting as a carrier for the antirust component/additive. In the instance indicated there seems to be a precipitation? please take up with supplier. You may also like to check for water ingress in the container, if stored for a long time.
