FIELD: technological processes.
SUBSTANCE: invention is related to method for adhesion of wood materials. Method consists in application of glue onto adhered surfaces and connection of adhered surfaces till complete hardening. Glue is previously exposed to treatment in permanent electric field with intensity of 636-1484 V/cm for 20 minutes. Glue KFZh on the basis of urea-formaldehyde resin with high pot life, polyvinyl acetate PVA glue or supraterm polyurethane glue 436 are applied onto adhered surfaces.
EFFECT: production of possibility to achieve high strength of adhesive joints of wood materials.
