Abstract: A floor mat article for removing and holding dust, mud, dirt, and water and a process for making a floor mat. The matting article can include a lofty nonwoven web of entangled fibers and a pressure-sensitive adhesive coating. The lofty nonwoven web can include organic crimped staple fibers which can be adhesively bonded together by a binder resin to form a three dimensional network of intercommunicated voids constituting at least 75% of the volume. The matting article can have a maximum density of 95 kilograms per cubic meter. The process can include forming a nonwoven web of crimped staple organic fibers; coating the nonwoven web with a binder resin; heat curing the coated nonwoven web; and applying a pressure-sensitive adhesive to a first major surface of the coated nonwoven web.

Abstract: The present invention is related to the usage of a composition of polyurethanes to obtain adequate materials for retention, resistance, reinforcement, covering and sealing of geological and architectonical structures, including the common used building materials such as brick, concrete, masonry, partition wall, clay, among others.

Abstract: The present invention is related to an abrasive cleaning item, comprising abrasive particles and a foaming agent which may or may not be microencapsulated particles distributed throughout a body of non-woven tri-dimensional fiber. The item, which may have any geometric configuration, offers the user the advantage of being able to have a cleaning product which, during a period of time similar or shorter than the useful life of the non-woven web laminated to the polyurethane foam, the foaming agent is diluted by its aqueous extraction and produces the foam effect or, otherwise, the microcapsules are slowly released by the mechanical effect of the cleaning.

Abstract: Provided is a heat-resistant masking tape suitable for electronics applications comprising a polyetherimide polymer film having a first surface and a second surface, an adhesive on the first surface, and a low adhesion agent on the second surface, wherein at least one of the polyetherimide film, the low adhesion agent and the adhesive includes micronized carbon black. Also provided is a process for making this tape and electronic circuits using this tape.

Abstract: A damping tape comprising: (a) a backing comprising a thermoplastic film having front and rear major surfaces; and (b) a sheet of resilient fibers having anchor portions bonded to the film at bonding locations spaced along the front surface of the backing, and arcuate portions projecting from the front surface of backing between the bonding locations, the lengths of some of the fibers in the sheet may be disposed in various different directions with respect to each other; and (c) a layer of adhesive covering significant portions of the rear surface of the backing. The tape may further comprise optional release liner over the adhesive layer. In some embodiments, the sheet of fibers may be covered with an overcoat layer.

Abstract: The a present invention is related to an abrasive cleaning article, made of spread abrasive particles and microencapsulated particles of an aromatizing substance contained in urea-formaldehyde walls, through a three-dimensional non-woven web of fiber that are bonded to the web by a resin adhesive. The item, of any geometric shape, offers the user a sensation of cleanliness due to the constant presence of a “fresh” scent associated to the fiber; the scent remains during the whole life of the abrasive item since the microcapsules break partially during the normal use of the item. The invention also refers to the production process of such abrasive item.
