  • Patent number: 6808757
    Abstract: A method of coating a substrate comprises the steps of applying a coating composition to selected areas of the substrate. The coating composition comprises a mixture including at least a reactive part. The reactive part comprises between 30% and 100% multi-functional material, and is photoinitiator free. The coated substrate is exposed, in a curing zone, to ultra-violet light from at least one lamp which has a power output of at least 140 watts per linear centimeter. The ultra-violet light initiates curing of the coating. A substantially inert atmosphere is maintained in the curing zone where the substrate is exposed to the ultra-violet light.

  • Patent number: 6773799
    Abstract: A process for manufacturing a decorative mainly isometric thermosetting laminate (1) comprising an isometric core (2), a primary surface layer (10) and optionally a secondary surface layer (20). 85 parts by weight of preferably organic particles are mixed with 15-85 parts by weight of a thermosetting resin such as phenol-formaldehyde resin, melamine-formaldehyde resin, urea-formaldehyde resin or mixtures thereof under powerful kneading in an extruder sot hat friction heat forms. The thermosetting resin is hereby bonded to or impregnating the particles. The particles possibly bonded to one another are parted whereby an agglomerate of resin and particles is formed. The particle/resin mixture is then dried to a water content of below 10%. The dried particle/resin mixture is then evenly distributed and continuously or discontinuously compressed in one or more steps under heat and pressure so that the resin finally cures, whereby an isometric core (2) is formed.
