FIELD: chemistry.
SUBSTANCE: bakelite lacquer is obtained by condensation of phenols with formaldehyde in water medium in presence of amine catalyst with heating and further cooling condensation product and addition of alcohol solvent in it until required viscosity is obtained. Mixture of phenol and cardanol is used as phenols with their molar ratio phenol:cardanol 1:0.003-0.472.
EFFECT: obtaining binding agent with increased storage term and improved specific electric resistance, lower phenol content.
