Sonneborn chemically oxidized petrolatums are mixtures of long-chained, branched and cyclic hydrocarbons and derivatives such as organic acids, oxi-acids and esters. The acids present in these oxidized petrolatums can be neutralized with bivalent metal oxides to ensure end products have a high molecular weight and wax-like nature with excellent water resistance and corrosion protection.
The preferred way to achieve neutralization is with calcium hydroxide or zinc oxide in a white spirit dilution. The white spirit solution of neutralized products delivers improved anti-corrosion coating properties by the addition of a high-molecular petroleum sulfonate. A certain quantity of microwax (Multiwax™ Witcovar 146) and/or petrolatum can be added to obtain special characteristics in the end product. The end product may also be sprayed or brushed on the metal surface for protection.
