Abstract
Water repellent treating compositions are based upon olefin and paraffin materials containing a substantial proportion of compounds containing from 20 to 24 carbon atoms. The treating compositions are especially useful for application to wood. Additives such as wood preservatives, alkyd resins and, in especially preferred compositions, organic ionizable compounds are included. The preferred compositions are useful for application to wood substrates which are subsequently electrostatically sprayed with a topcoating.
