    摘要: A shingle having a headlap section and a buttlap section with at least one portion of the buttlap section having a relatively uniform color and another portion of the buttlap section having a color gradient or gradation from light to dark. An illusion of depth or thickness is created on the portion of the buttlap section having the color gradient. The buttlap section defines in part the exposed weather surface of the associated shingle. The relatively uniform color portions may be formed on tabs or dragon teeth and the color gradient formed on a backer sheet disposed beneath the tabs. Openings between adjacent tabs expose the color gradient to view. A plurality of horizontal striations may be used to establish the desired color gradient from light to dark. The amount of tone and contrast may be selected to create the desired illusion of depth or thickness. The amount of contrast may be varied depending upon the color selected for each shingle. The number of horizontal striations and their width may also be varied to provide the desired color gradient.

    摘要: Panels of composite wood material are formed in a wet process which includes depositing a layer of wet composite wood material in a mat on a press wire screen mesh and moving the screen mesh to carry the mat into a pressing position between a pair of spaced apart pressure plates having generally matching, contoured facing surfaces for shaping the outer face and a smoothly contoured back face of the panel. The back face of the panel is not flat and generally follows or matches the shape or contour of the outer face so that regions of high fiber stress and dense, brittle areas of high fiber compression are generally eliminated. The resulting finished panels having excellent machining qualities, more uniform surface coating absorption characteristics, more uniform thickness and less rapid moisture absorption properties, along with a lower tendency to check, crack or split.

    摘要: A solventless, fluid epoxy resin composition is storage-stable against separation of phases for at least one year, and when cured provides adhesive bonds of improved peel strength at room and low temperatures without loss of lap shear strength at room and elevated temperatures. The composition comprises an epoxide group-containing compound having in situ polymerized, elastomeric particles colloidally dispersed therein, and as curing agent a poly(oxyhydrocarbolene)diamine compound and optionally, and preferably, a cure accelerator.
