Abstrakt: A one-component organosilicon composition based on a Lestosil SM-NT block copolymer solution containing an optimal ratio of linear polydimethylsiloxane and ladder phenylsilsesquioxane units in an organic solvent was developed. A heterosiloxane solution containing boron and zirconium atoms in alkoxysilane in the siloxane chain and special additives that increase the operational properties of coatings was used as a curing system. The composition is to be used to obtain heat-resistant electrically insulating and moisture-resistant coatings with improved physical and chemical properties for use as protective materials in microelectronics and electronic devices.
