Inhibitive Aqueous Extracts Formed with Certain Oleoresinous Binders Inhibitive aqueous extracts form with certain oleoresinous binders. Components of the binder, such as carboxylic and hydroxyl groups, form complexes with either the zinc phosphate or the intermediate compounds formed when the zinc phosphate becomes hydrated and dissociates. These complexes can then react with corrosion products to form a tightly-adhering, inhibitive layer on the substrate [21,39,43 6,52]. 

Red lead pigments are one of the oldest and most popular types of anticorrosive pigments, mainly used for primers for metals. They are indirect inhibitors and require reaction with a selected resin system. When used in linseed oil or other oleoresinous binders, they react with acidic groups in the resin and form lead soap, which has an inhibitory effect. They are no longer used in the coating industry due to the toxicity associated with lead. 

Oleoresinous binders are those which are manufactured by heating oils and either natural or pre-formed synthetic resins together. The oleoresinous vehicles have largely been replaced by alkyds and other synthetic resins. 

The majority of binders are organic materials such as oleoresinous varnishes, resins containing fatty acids from natural oils (alkyd, epoxy esters, urethane oils), treated natural products (cellulose nitrate, chlorinated rubber), and synthetic polymers. There are two general t5 es of organic binders, convertible and non-convertible.
