A process for preparing an anti-corrosive composition, comprising the steps of stirring the active material of formula
- wherein R is an aliphatic chain of C12 to C20 and n≦20;
- adding an anti-corrosive pigment and a filler mixture slowly enough to the stirred active material so that they disperses quickly in active material and mixed and stirred to form a blend;
- adding a mineral oil and mixing it followed by filtering the resulting product through a 300 mesh filter.
An anti-corrosive composition comprising:
- an active material of formula
- wherein R is an aliphatic chain of C12 to C20 and n≦20, and the active material is present in an amount of 30-45 parts by weight of the composition;
- an anti-corrosive pigment;
- a filler present in an amount of 35 to 40 parts by weight of the composition;
- and
- a diluent or carrier present in an amount of at least 10 parts by weight of the anti-corrosive composition,
- wherein the composition comprises at least one part by weight of the anti-corrosive pigment.
