The invention provides a waterproofing membrane which does not require a removable release sheet but which nevertheless bonds to post-cast concrete and facilitates water-tight sealing at membrane-to-membrane overlaps. The waterproofing membrane comprises a carrier and pressure-sensitive adhesive (PSA) layers, an inorganic particle layer having particulate bodies which are partially embedded in the PSA and which have an average particle size less than the average thickness of the PSA layer, and an anti-submarining nano-silica-containing coating layer attached to un-embedded portions of the inorganic particles to prevent total embedding into the PSA when the membrane is rolled or unrolled, whereby water-tight seams are facilitated between overlapped portions of adjacently installed waterproofing membranes, and whereby the water-tight seam is achieved preferably using only detailing or waterproofing tape and without the additional use of a liquid primer, mastic, or other coating.

Provided is a self-adhesive waterproof sheet with a modified synthetic rubber and more particularly, the self-adhesive waterproof sheet with a modified synthetic rubber includes an asphalt compound layer; a protective film layer that is formed on the asphalt compound layer and is oriented in two directions with respect to elongation by mixing high density polyethylene (HDPE) and methallaocene low density polyethylene (M.PE) at a ratio of 30 wt % to 70 wt % :30 wt % to 70 wt %; and a release sheet formed to be detachably attached to a lower portion of the asphalt compound layer.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

Non-limiting embodiments of the present disclosure relate to a method comprising: obtaining asphalt shingle waste (ASW) and performing grinding, screening, and separating steps on the ASW. In some embodiments, granules are removed from the ASW. In some embodiments, the method transforms ASW into ASW powder. In some embodiments, the ASW powder is formed into a plurality of briquettes. In some embodiments, at least one of: the ASW powder, the plurality of briquettes, or any combination thereof is fed into a mixing process that results in an ASW powder filled coating. In some embodiments, the ASW powder is formed into an adhesive composition.

Provided is a masking sheet for anodizing, the masking sheet comprising a substrate having first and second faces, and a PSA layer placed on the first face side of the substrate. Here, the substrate is a non-metal substrate. The elastic modulus Et of the masking sheet and the thickness Hs of the substrate satisfy the next relation 0.7 N/mm<Et.Math.Hs.sup.3.

A bituminous composition is used as an adhesive binder. The bituminous composition has at least one acidic additive of general formula (I): R(COOH)z in which R is a linear or branched, saturated or unsaturated hydrocarbon-based chain having from 4 to 68 carbon atoms, preferably from 4 to 54 carbon atoms, more preferentially from 4 to 36 carbon atoms and z is an integer ranging from 1 to 4, preferably from 2 to 4.

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.
