ABSTRACT:
There is disclosed a method for providing an improved abrasion resistant coating on solid substrates such as plastic articles and solid articles prepared thereby having on the surface such abrasion resistant coating. A solid substrate is coated with an organosilanol-type coating liquid comprising organosilanol molecules, or a precursor thereof or a partial condensation product thereof. At least 90 mole percent of said organosilanol molecules are trifunctional silanol molecules of the formula RSi(OH).sub.3, R being a hydrocarbon radical, and at least 50 mole percent of said trisilanols being an alkyl trisilanols of 1-3 carbon atoms or phenyl trisilanol. Preferably, at least 70 mole percent of the trisilanol is methyltrisilanol. After the coating is cured by a conventional means, it is post-treated by an electron beam irradiation to afford an abrasion resistance far superior to that obtained from organosilanol coating liquids without electron beam irradiation post-treatment.
