Nouvelle laque à base de silicium, son emploi en tant que revêtement de substrat et les substrats ainsi obtenus.

摘要

The present invention relates to a lacquer obtained by the process comprising the steps of: (i) precondensation of: a) 1 to 10 mol % of at least one silane of the formula SiR4; b) 20 to 94 mol % of at least one organic silane of the formula R"m(R"'Y)nSiX(4-m-n); c) 5 to 30 mol % of at least one organic silane of the formula R"pSiX4-p; d) optionally 0 to 10 mol % of at least one low-volatility metal oxide; and (ii) hydrolysis condensation of the precondensate of step (i) in the presence of the stoichiometric amount of water. The present invention also relates to a process for the obtention of a coating on substrates which comprises the steps of applying the lacquer and curing same. The invention also relates to the thus-coated substrates.
