Abstract
PROCESSO PARA OBTENçãO DE UMA CAMADA DE PROTEçãO PERMANENTE SOBRE SUPERFìCIES DE METAL NOBRE POR MEIO DE REVESTIMENTO COM SOLUçõES COM BASE EM POLISSILAZANO. A presente invenção refere-se a um processo para revestimento de superfícies de metal nobre ou ligas de metais nobres com uma solução contendo um polissilazano da fórmula (1) em que n é calculado de tal modo que o polissilazano apresente um peso molecular médio de 150 até 150.000 g/mol, bem como um solvente e um catalisador, caracterizado pelo fato de que antes do revestimento com a solução de polissilazano, sobre o objeto a ser revestido é aplicado um primer contendo enxofre com base em silano para aperfeiçoar a aderência. Além disso, a invenção refere-se a revestimentos que foram preparados com o processo de acordo com a invenção.
