Abstract:
Methods of compounding nanoparticles with a resin, e.g., a curable resin and one or more surface modifying agents are described. The methods use wet milling technology, including both continuous and batch milling processes, and can be used to functionalize the nanoparticles and disperse the functionalized nanoparticles into the resin system in a single process. Methods of compounding curable resin systems containing reactive diluents are also disclosed.
Abstract:
A method of making a buff-coated article includes disposing a tie layer on at least a portion of a major surface of a substrate and buff-coating a powder onto at least a portion of the tie layer. Buff-coated articles are also disclosed.
Abstract:
The use of nanoparticles, including surface-modified silica and calcite nanoparticles, as processing aides for pultrusion is described. The methods include combining a resin system containing a resin and the nanoparticles with continuous fibers, pultruding this combination, and at least partially curing the resin. The methods are suitable for use with a wide variety of resins and fibers, and may be used to reduce the pull-force at a fixed fiber volume loading, increase the fiber volume loading, or both. Pultruded parts made by these methods and pultruded parts with high volume loadings of fibers are also described.
Abstract:
The invention relates to an article comprising an elongated pressure sensitive component in contact with a user. The pressure sensitive component forms a seal 7 between the user and the article when a minimum seal pressure is applied on the pressure sensitive component. The seal 7 comprises a signal pathway or an inductive loop indicative of a complete seal between user and article at the minimum seal pressure applied along the entire length of the pressure sensitive component.
Abstract:
A method comprises exposing a particle coating disposed on a nonwoven fiber web comprising thermally-softenable fibers to pulsed electromagnetic radiation having at least one wavelength in the range of 200 nm to 1000 nm. The particle coating comprises distinct particles that are not chemically bonded to each other, and are not retained in a binder material other than the thermally-softenable fibers. Also disclosed are nonwoven articles comprising a thermally-softenable nonwoven fiber web having a particle coating disposed thereon. The particle coating comprises distinct particles that are not chemically bonded to each other and are not retained in a binder material other than the thermally-softenable nonwoven fiber web. The particle coating is at least 60 percent retained after a one minute immersion in isopropanol at 22°C.
