FIELD: anti-burning, anti-adhesion and wear-resistant coats; food-processing industry.
SUBSTANCE: proposed coat is made on base of powder composition containing the following components, parts by mass: fluoro-containing copolymer in form of fluoroplastic 4MБ, 100.0; boron nitride, 0.3-0.5; titanium dioxide, 0.5-1.0; chromium oxide, 1.0-1.5 and diphenyl silandiol, 0.05-0.5. Dispersity of powder composition ranges from 20 to 80 mcm. Prior to application, composition is subjected to heat treatment at temperature of 100°C continued for an hour and followed by fusion of surface at temperature of 380-390°C continued for 2 h, after which composition thus treated is cooled to room temperature at rate not exceeding 40°C/h.
EFFECT: enhanced stability of separating effect between article and foodstuff without application of edible oils.
