Chemically oxidized petrolatums are mixtures of long-chained, branched, and cyclic hydrocarbons and their derivatives like organic acids, oxi-acids and esters. The acids present in our oxidized petrolatums can be neutralized with bivalent metal oxides, giving end products of a high molecular weight and wax-like nature with excellent water-resistant properties and corrosion protection.
Neutralization can be achieved preferably with calcium-hydroxide or zinc-oxide in a white spirit dilution. The white spirit solution of neutralized products gives improved anti corrosion coating properties by the addition of a high-molecular petroleum sulfonate. To obtain special characteristics in the end product, it is also possible to add a certain quantity of microwax (Witcovar 146) and/or Petrolatum. The end product may be sprayed or brushed on the metal surface to be protected.
