摘要:
A kraft paper sheet material includes a kraft paper sheet and an asphalt layer on one major surface of the kraft paper sheet that is partially absorbed into the kraft paper sheet. The asphalt layer has a fungi growth-inhibiting agent therein in amounts that result in the kraft paper sheet material having more fungi growth resistance than the kraft paper sheet without the asphalt coating layer. Water vapor transmission retarding facings for faced insulation assemblies and other water vapor transmission retarding coverings are made with kraft paper sheet material.
摘要:
A modified bitumen sheet material (12) and method for a protective moisture barrier, particularly for masonry surfaces (42). The sheet material has a bitumen layer (14) modified by the addition of a minor amount of a long-chain polybutadiene-isocyanate urethane polymer and optionally, a modifying amount of hydrocarbon oil to provide stable, non-flow and selected tackified surface properties to the bitumen layer (14). The sheet material (12) includes a releasable casting paper film (16) on one surface of the bitumen layer (14), to be removed prior to use, and a cross-linked polyethylene film (12) bonded to the other outer surface of the bitumen layer (14) as a handling or moisture barrier sheet. The sheet material (12) is prepared by casting the hot, melted bitumen as a layer (14) onto a casting paper sheet (16) and applying the outer film to the exposed bitumen surface to bond to the top surface.

摘要:
A recycled asphalt roofing material (20) for use on sloped roofs, which provides the required elevated melt point without using prior art methods of oxidising the asphalt prior to incorporation into the roofing material is provided. The recycled asphalt roofing material (20) is made up of approximately 30% flux asphalt and approximately 70% reclaimed asphalt roofing material. The fibrous backing in the reclaimed material modifies the asphalt in such a way as to provide the required elevated melt point. The manufacturing process for recycled fibreglass mat-based roll and shingle roofing, in its preferred embodiment, consists of impregnating a roofing material backbone (22), such as a fibreglass or polyester mat with recycled asphalt material to form inner and outer layers (24) of recycled material and then applying optional second inner and outer layers (26) of standard asphalt coating to the inner and outer layers of the recycled material (24). The second coating encapsulates and seals the recycled material and thus ensures that the recycled roofing material will have the same longevity as prior art asphalt roofing materials.
摘要:
An adhesive rubber article of the type having a release liner covering its tacky, adhesive surface to prevent the adhesive rubber article from adhering to various substrates or to itself prior to its intended use includes an impression or mark presented on one or more surfaces for facilitating the alignment and application of the adhesive rubber article on one or more substrates. The release liner has been scored, perforated or otherwise cut in a longitudinal direction of the article such that the scoring of the release liner further produces a visual guide on the adhesive rubber article. Thus, upon removal of the release paper, the guide may be used to align and apply the adhesive rubber article to the various substrates. These adhesive rubber articles are particularly useful within the roofing industry for bonding panels of rubber membranes together or for use as flashing.

摘要:
Verfahren zur Herstellung einer Kohlenstoff enthalten den Schicht, Kohlenstoff enthaltende Schicht, Verwendung einer Kohlenstoff enthaltenden Schicht und Vorrichtung zur Durchführung eines Verfahrens zur Herstellung einer Koh lenstoff enthaltenden Schicht. Eine Kohlenstoff enthaltende Schicht (C) soll auf einem Substrat (S) durch Aufsputtern hergestellt werden können, wobei die Kohlenstoff enthaltende Schicht (C) auf beinahe jedem Substrat (S) gut haftend und als sehr dünne Schicht aufgetragen werden kann und wobei die Kohlenstoff enthal tende Schicht (C) auch eine geringe Leitfähigkeit aufweist. Beim Aufsputtern werden in die Kohlenstoff enthaltende Schicht (C) Kohlenwasserstoff -Molekülteile oder Kohlen wasserstoff-Moleküle mit eingebaut. Eine so beschaffene Kohlenstoff enthaltende Schicht (C) haftet auf beinahe jedem Substrat, ist beinahe kratzfest und hilft Aufladungen und Kontaminationen bei Beschuß mit geladenen Teilchen zu vermeiden.
摘要:
Bio-degradable, high-barrier packaging materials and methods for production are provided. The present high-barrier packaging materials include a substrate having a print side and a back side, a coating having nano pigments on the print side and a metalized film applied to the back side with a binding layer. Preferably, at least one of the metalized film and the binding layer includes polylactic acid. Moreover, the back side preferably also includes a polylactic acid heat seal layer.

Provided herein are novel polymeric coating materials for direct digital imaging by laser. More specifically the novel coating materials are thermally reactive near infrared absorption polymers designed for use with near infrared laser imaging devices. This invention further extends to the preparation and methods of use of the novel materials. The invention is particularly useful in the preparation of lithographic printing plates for computer-to-plate and digital-offset-press technologies. The invention extends to photoresist applications, to rapid prototyping of printed circuit boards and to chemical sensor development.
