Abstract: An adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac contains 35-75% by weight of novolac, less than 25% by weight of water, and 10-40% by weight of an aliphatic divalent, trivalent alcohol. The adhesive composition may also contain up to 20% by weight of filter, based on the amount of novolac, water and alcohol. In a method for preparing the adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac, the novolac is produced by conventional condensation, whereupon an aliphatic divalent, trivalent or tetravalent alcohol is added and water in the novolac is distilled off, resulting in an adhesive composition as defined above. Alternatively, the amount of water can be reduced in the condensation of the novolac to be replaced with an aliphatic divalent, trivalent or tetravalent alcohol.

Abstract: A method for determination of parameters of wood panels, which comprises analyzing the raw wood material/panels at a moisture content <10% by a spectrometric method giving spectral data, and comparing spectral data with reference data from reference material/panels calibrated to known parameters of panels produced from the reference material or of the reference panel by multivariate analysis. Control of process variables influencing parameters of the panels, which comprises analyzing the material/panels, linking spectral data into a combination with desired parameters, and comparing the combination with reference combinations consisting of reference data from reference material/panels linked with known parameters of the reference material/panels, the reference combinations being calibrated to known variables by multivariate analysis.
