Abstract
FIELD: sealing coatings. SUBSTANCE: preliminary clarified 20-25% solution of polymethylsilazane in aromatic hydrocarbon solvent at concentration 5-10 wt.-% as 100 wt.-% polymethylphenylsiloxane and 0.04 wt.-% γ-aminopropyltriethoxysilane (АГМ-9 product) is added to the solution of polymethylphenylsiloxane (varnish KO-921) in aromatic hydrocarbon solvent. Concentration of composition is brought about up to 15-20 wt.-% and treated with ultrasonic field at frequency 15-25 kHz for 2-3 min and transducer is placed into composition. Then composition is treated together with transducer by ultrasonic field for 2-3 min, concentration of composition is increased up to 30-35 wt.-% by addition of undiluted composition followed by treatment by ultrasonic field again for 3-6 min. Transducer is removed and coating is hardened at natural conditions for 24-36 hr. Invention ensures to obtain cold hardening coating working under conditions of cyclic increased temperatures action there are no defects after 50 cycles of heating transducer with coating up to 250 C and cooling up to the room temperature, insulation resistance is above 1 MOhm. EFFECT: enhanced quality of coating. 1 tbl
