Abstract: There is disclosed a resin-coated overlay for bonding to solid substrates, and which imparts improved waterproofing and chemical resistance to the resulting resin-coated overlaid solid substrate. Depending upon the desired end use of resin-coated overlaid solid substrate, the resin-coating may be modified to impart desirable surface features and/or characteristics. For example, additives such as waxes, oils, silicones, fluorocarbons and fatty acid compounds may be used to promote the release of concrete from forms made of solid substrates overlaid with the resin-coated overlays of the present invention. Moreover, resin-coated overlaid solid substrates may be produced having a surface which is suitable for painting and which accepts application of various tape products. Other modifications are disclosed which can be used to gain desirable cure speed, cost, and chemical/mechanical properties in the resin-coating.

Abstract: A specially constructed solid core door is disclosed having a solid core material of particleboard or other suitable material, wood stiles bonded around the periphery of the edges of the core material, a hardwood skin having a minimum thickness of 1/8 inch bonded to the front and rear surfaces of the core material and a phenolic resin-impregnated paper overlay overlying and bonded to the exposed faces and backs of each of the hardwood veneers. The exposed face of the resin-impregnated paper is preferably deeply embossed during bonding of the paper to the veneer with a texture such as a wood grain texture. The door has twice the warp resistance of standard wood doors. The resin impregnated overlayed surfaces provide excellent dent resistance, easy repairability, resistance to checking or crazing, and long paint life (approximately 2 to 3 times that of the standard wood faced door).

Abstract: A drive arrangement pressurizing system and method for a veneer edge gluer apparatus having a low pressure, constant-drive infeed crowder section and a high pressure intermittent-drive outfeed crowder section for producing a continuous veneer ribbon which is moved in a straight line path of travel as it issues from the edge gluer.
