Abstract

<p>PURPOSE: Provided is a method for desmearing resin accretions from the surface of a substrate and texturing a resin without solvent swelling and permanganate etching and without using an electrolyte such as nitric acid capable of attacking specific metal. CONSTITUTION: The method comprises the steps of generating a free radical; and contacting the surface of a substrate having resin accretions with the free radical to desmear the surface of resin accretions and to texture a resin. Preferably the free radical comprises a hydroxyl radial, a halogen radical or their mixture, and is generated chemically, by thermal decomposition or by pyrolysis. Also the method comprises the steps of generating a free radical; and contacting the surface of a substrate having resin accretions with the free radical to remove some of the resin accretions; and contacting the surface of a substrate with a promoter to remove the additional resin accretions from the surface of a substrate and to texture a resin. Preferably the promoter comprises a permanganate etching solution.</p>
