<p>A plastic article having a number of surfaces with at least one surface being modified by contacting that surface with a reactive gas atmosphere containing F2, Cl2, O2, Ozone, SO3, oxidative acids, or mixtures thereof, at a temperature and gas partial pressure sufficient to increase the surface energy of the at least one surface being modified to at least 40 dynes/cm at a temperature of 20 °C, to enhance bonding of non-slip polymer coatings to the modified surface, to which coatings elastomeric or rigid particles may be admixed for imparting a surface profile and increasing the coefficient of friction between the coated surface and the counter-surface.</p> |
