摘要:
As described herein, the invention includes a building underlayment sheet that comprises an underlayment lamina having a top surface and a bottom surface. The bottom surface includes an interior portion and a selvage portion that extends from the interior portion of the bottom surface to a terminal distal edge of the sheet and the interior portion of the bottom surface bears a self adhesive layer. The selvage portion of the bottom surface bears a bonding composition that is capable of bonding to a top surface of a second underlayment lamina to form a full lap joint. In some embodiments, the self adhesive layer includes an asphalt, a polymer such as poly(styrene-butadiene-styrene)(SBS), and a tackifier, and/or the bonding composition includes asphalt, a polymer such as poly(styrene-butadiene-styrene), ground tire rubber (GTR), and tackifier. Also included are building assemblies that include the application of one or more of the underlayment sheets to a building surface, such as a roof surface and methods of installing the underlayment and waterproofing a roof surface.
摘要:
The present disclosure relates to a bonding arrangement (10) for the assembly of structures, the structures comprising at least one substrate member (50) to which at least one coating structure (20) is applied, the substrate member (50) and the coating structure (20) comprising a common interface which forms at least one bond, the at least one bond being designed as an adhesive bond. In order to provide a new and improved bonding arrangement (10), especially for use in an aircraft or spacecraft, which is designed to overcome problems of bonding arrangements (10) under Mode I loading stress and which is designed or configured particularly to create a bond design which is incapable of locally loading the adhesive bond above the peel strength, a bonding arrangement (10) is disclosed with a coating structure (20), which is split into a plurality of neighboring structural elements (22) spatially separated from each other, and at least one supporting member (30) is provided, which comprises a plurality of recesses (32) receiving the structural elements (22) in operating position.

A substrate assembly of heterogeneous materials includes: a substrate (2) having an outer surface (23) and formed with first and second channels (21, 22), the outer surface (23) havingfirst, second and third regions (231, 232, 233), the first and second regions (231, 232) being non-coplanar, the second and third regions (232, 233) being non-coplanar, the first channel (21) extending inwardly from the first region (231) in a first direction (213), the second channel (22) extending inwardly from the third region (233) in a second direction (223) that crosses the first direction (213); and a mounting seat (3) having an outer layer (33) and first and second inner protrusions (31, 32). The outer layer (33) is formed on the first and third regions (231, 233) . The first and second inner protrusions (31, 32) extend respectively into the first and second channels (21, 22).
