The invention relates to a process for coating biscuit tiles wherein at least one coating composition is applied to the biscuit tile, characterised in that the composition comprises silica particles, a substantially silicon-free polymerisable compound, and a silane of the general formula R1-Si(OR)3, wherein R1 is a substantially silicon-free polymerisable group and R is a hydrocarbon radical. The process according to the present invention does not require the reheating step which is compulsory when preparing (glazed) ceramic tiles. Nonetheless, an abrasion-, scratch- and fire-resistant coating layer is obtained.
L'invention concerne un procédé de revêtement de tuiles de biscuit selon lequel au moins une composition de revêtement est appliquée sur la tuile de biscuit. Ce procédé est caractérisé en ce que ladite composition comprend des particules de silice, un composé polymérisable sensiblement exempt de silicium ainsi qu'un silane de formule générale R?1¿-Si(OR)¿3?, dans laquelle R?1¿ représente un groupe polymérisable sensiblement exempt de silicium et R représente un radical d'hydrocarbure. Le procédé de l'invention rend superflu l'opération de recuisson laquelle est obligatoire en cas de préparation de tuiles en céramique (émaillées). On obtient ainsi une couche de revêtement anti-abrasif, anti-rayures et résistant au feu.
