Abstract
The invention relates to an ink jet pen having exposed surfaces which are coated with a polymeric material. The polymeric material is treated with ultraviolet energy at a wavelength and for a period of time sufficient to increase the surface energy of the coating to thereby enhance the adhesive properties of the coating. The coated polymeric material and treated pen exhibits improved corrosion resistance and are more compatible with adhesives used to assemble components of the pen than similar untreated coatings.
