An adhesive system with material and structural heterogeneity is described. The adhesive system comprises a tape having a spatially heterogeneous physical property, the spatially heterogeneous physical property is configured to enhance the adhesive strength of the adhesive system when the adhesive system is in contact with a substrate and/or attain adhesion directionality. The spatially heterogeneous physical property can include a bending stiffness. Heterogeneous variations in the bending stiffness can be achieved by variations in the tape's thickness, elastic modulus and/or Poisson's ratio. Heterogeneity in thickness can be attained by mold pressing and/or patterned laminated structures. Elastic modulus heterogeneity can be achieved by masked irradiation of the tape, where the tape is made of an irradiation-sensitive material. Also described is an adhesive system with a patterned film that exhibits adhesion directionality when the adhesive system is in contact with a substrate.

Adhesive articles, particularly useful as reusable closures, comprising a moisture resistant substrate and a removable adhesive covering at least a portion substrate surface, the adhesive having a Moist Loop Test result of at least about 25 N/25mm at a test plate temperature of 5 DEG C. The closure may also include a permanent adhesive covering another portion of the substrate surface. The adhesive articles provide easy application to packages and exhibit good adhesion performance in the presence of moisture, such as from refrigerated or frozen food packaging.

The aim of the invention is to provide an improved solution for an adhesive connection for the planar adhesion of components, in which the adhesive connection has a non-uniform stress distribution in different regions of the adhesive surface. According to the load, such as the distribution of stress, an adhesive should be adaptable as well as possible in terms of its properties to the stress curve within the adhesive surface, wherein advantageous interactions between the respective adhesive adaptations should be exploited. In this way, a stress-optimized adhesive connection for the overlapping connection of at least two components (5) using a single adhesive (14) is provided, said adhesive comprising at least two components, wherein said components are mixed together and the adhesive (14) is applied at least in the overlap region of the components (5) as an adhesive surface (4) onto at least one of the components (5), and the components (5) are joined correspondingly in an overlapping manner, the adhesive (14) being curable. According to a mechanical stress of the adhesive connection in two, three or more regions of the adhesive surface (4), the adhesive (14) has in these regions of the adhesive surface (4) corresponding mixing ratios (1, 2, 3, n) of the components.
摘要:
A flooring tape, for securing a first flooring unit adjacent to a second flooring unit is described. The flooring tape has two sides, a first adhesive side and a second non-adhesive side. The first adhesive side is made up of three portions, a first portion, a second portion and a third portion, the third portion positioned between the first and second portions. The first portion and the second portion have a flooring adhesive layer applied thereto for forming a bond with the first and second flooring units. The third portion has a water resistant adhesive layer applied thereto.
摘要:
An article including a release liner with an adhesive layer disposed thereon, the adhesive layer including a plurality of stripes of a first pressure-sensitive adhesive and of a second pressure-sensitive adhesive, arranged in a generally alternating pattern. The first pressure-sensitive adhesive is a silicone-based pressure-sensitive adhesive that includes a silicone block copolymer elastomer comprising hard segments that each comprise at least one polar moiety, and the second pressure-sensitive adhesive is an organic polymeric pressure-sensitive adhesive.
摘要:
The invention relates to a method for gluing a fastening element on a carrier component of an automobile, wherein the fastening element comprises a contact surface for gluing onto the carrier component and at least one fastening section facing away from the contact surface, wherein on the fastening section a component to be fastened on the carrier component can be fastened, with the steps: a contact glue for preliminarily holding the fastening element on the carrier component is applied to a first area of the contact surface, a permanent glue for permanently holding the fastening element on the carrier component is applied to a second, different area of the contact surface, the fastening element is placed onto the carrier component with its contact surface, whereby the contact glue preliminarily holds the fastening element on the carrier component until the permanent glue is hardened and thus permanently holds the fastening element on the carrier component. The invention further relates to a corresponding fastening element.
