Abstract
Abstract A METHOD OF AND COMPOSITION FOR PROMOTING ADHESION BETWEEN PLATED METAL AND A PLASTIC SUBSTRATE, IN WHICH THE ACTIVE AGENT IS PROVIDED IN FINELY DIVIDED DISPERSED OR COLLOIDAL AQUEOUS EMULSION FORM. THE ACTIVE AGENTS ARE ANY OF A GROUP OF LOW MOLECULAR WEIGHT ORGANIC UNSATURATED COMPOUNDS OF THE FATTY ACID TYPE, AND MORE ESPECIALLY OF THE GROUP OF NATURALLY OCCURRING PRODUCTS SUCH AS LINSEED, TALL, TUNG AND CASTOR OILS, TURPENTINE AND SIMILAR WOOD ROSINS. THESE, WHEN DISPERSED IN WATER TO PROVIDE STABLE EMULSIONS, ARE USED AS A PRETREATMENT BATH FOR PLASTIC SUBSTRATES, PRIOR TO PLATING OF THE SUBSTRATE, IN ORDER TO PROMOTE THE FORMTAION OF A STRONGER BOND BETWEEN THE METAL PLATE AND SUBSTRATE.
