    Abstract: A method of absorbing resin into part of a panel of particleboard to provide local strength increases in that part. The method comprises subjecting the part to an electric field, immersing the panel in the resin; and then resubjecting the panel to the electric field to cure the resin. A particleboard panel is also disclosed. The panel has a main body with a specific gravity in the range 0.2 to 0.5 but at least one area on its periphery has a specific gravity in the range 0.7 to 1.0. The one area is impregnated with a synthetic resin. The panel is particularly useful in door production as it is strong but cheap.

    Abstract: A novel process for applying cured thermoset resinous coatings to various kinds of substrates and in particular, to thin metal substrates, is disclosed. Finely divided thermosettable resinous particles containing a solid catalyst are introduced into a region of a plasma arc generated flame having a temperature greater than the melting point of said resin. The residence time of said resinous particles in the vicinity of said flame is maintained for a period sufficient to liquify substantially said particles and to initiate polymerization of the thermosettable resin particles. The liquified resin particles are propelled towards a substrate with sufficient velocity to cause said liquified resinous particles to impact with sufficient force to cause said particles to flow upon said substrate to coat same with a continuous, thin coating. The coated substrate is then cooled at a rate sufficiently slow to permit said coating to cure. The plasma flame must be located sufficiently near the substrate so that the resinous particles possess sufficient thermal and kinetic energy to flow into a thin coating retaining sufficient energy therein to continue curing to a thermoset state without addition of energy. The kinetic energy of the particle facilitates formation of a thin, uniform coating and creates additional thermal energy upon impact with said substrate.
