Composite wood materials in the form of chipboards based on urea-formaldehyde resins (grades KF-MT-15, KF-NFP, etc.) are widely used in furniture production. However, one of the main shortcomings of chipboards is their toxicity associated with the release of a gas harmful to humans – formaldehyde. Its maximum permissible concentration in the air of a residential building should not exceed 0,01 mg per m 3 of air. The paper shows one of the solutions to the problem of reducing the toxicity of chipboards
