Abstract
Shaped aluminum bars fresh from an extruder machine are coated with a specific organopolysiloxane composition while remaining uncooled and staying at temperatures not lower than about 250.degree. C, or at a temperature between about 550.degree. and 250.degree. C. The thus coated aluminum bars are then, preferably, subjected to annealing. The coatings formed on the surfaces of the aluminum materials have a superior resistance to attack by chemicals, weather, stains and heat as well as excellent adhesion and mechanical properties.
