    Abstract: An apparatus is configured with a component having a coating comprising a material in a first phase (e.g., solid and/or liquid phase) with a transition temperature. The component is mechanically and/or electrically attached to a substrate. Exposure of the coating to a temperature that meets or exceeds the transition temperature causes the material to undergo a phase change. The phase change of the material alters the position of the component, including separation of the component from the substrate. The separation disrupts the attachment, thereby mitigating damage to the substrate and/or component.

  • Publication number: 20150107488
    Abstract: A composition which, when mixed with a polymer composition, allows for the formation of a continuous and cohesive film. The film is characterized in that it provides water, grease and oil resistance, provides a water vapour barrier and can used as wax replacement treatment and a top coat for flexible packaging, but also on other substrates. This film is formed at a very fast set speed without the need of thermal energy. The composition contains i) calcite alone or in combination with a salt of one or more of myristic, palmitic and stearic acid; and also ii) a C9-C18 fatty acid complex of a metal ion, the metal ion having an oxidation state of at least 3. The composition is incorporated in material such as cellulose based material or plastic based material.

  • Publication number: 20140371364
    Abstract: The present invention relates to a polymer powder which comprises nylon-11, and to the use of this powder for shaping processes, and also to moldings produced from this polymer powder. The shaping processes are layer-by-layer processes which use powders, where regions of the respective layer are selectively melted via introduction of electromagnetic energy. The selectivity may—with no intention of restricting the invention thereto—be achieved via masks, application of inhibitors, of absorbers, or of susceptors, or via focusing of the energy introduced. After cooling, the regions then solidified can be removed in the form of moldings from the powder bed. Compared with moldings composed of conventional powders, the moldings constructed using the inventive powder by one of the inventive processes exhibit marked advantages in terms of component properties, particularly surface finish.
