Influence of electromagnetic treatment of the mineral filler on properties of the adhesive compositions for plywood production. The influence of pre-activation of natural mineral filler zeolite (clinoptilolite) in the electromagnetic microwave field (EMF) and in a weak pulsed magnetic field (IMP) on the physical, mechanical and chemical properties of adhesive compositions were investigated. The differences in the mechanisms of exposure of EMF and IMP on mineral filler in adhesive composition were identified. Decrease of free formaldehyde content from cured adhesive composition is 23 %. Increase of acidity and reduction of gel time were determined. Addition of clinoptilolite into the adhesive composition increases the strength of the adhesive layer: at untreated sample by 6 %, treated in a weak IMP by 14 % and activated in EMF by 23 %.
