Abstract
A process of bonding surfaces, such as a wood veneer to a sheet of hardboard, or to a number of wood veneers to form a plywood panel, comprises applying separately and successively to at least one of the surfaces to be bonded, first, a spray coating of a liquid hardenable resinous component, and second, a component comprising a powder hardener for the liquid resinous component and, optionally, a filler, bringing the surfaces together and allowing the composition to dry. The liquid resinous component may be a urea-formaldehyde resin and the powder component include both a filler and hardener such as woodflour, slate-flour, wheat-flour, starch, clay, calcium sulphate, chalk as the filler and, as the hardener, ammonium salt which may have added to it citric acid, oxalic acid, tartaric acid, aluminium sulphate, magnesium silicofluoride or the like. The liquid resinous component may be a phenol-formaldehyde resin and the powder component be as above or coconut shell flour, or chalk as the filler and paraformaldehyde or powdered tannin as the hardener. A curtain coater is used to apply the liquid resinous component and the powder component is applied by a vibrating screen. A slow acting hardener may be incorporated in the resinous component as well as a rapid acting hardener in the powder component. Examples are given of a panel and door made by the process.
