A dual lap high strength adhesive for sheet membrane application, having reflectivity granular particle layer to fully bond to concrete/shotcrete, and a method of making, and using same. More particularly, the invention encompasses a below grade, blind side, waterproofing sheet membrane with an inventive high strength adhesive, and having at least one layer of reflectivity granular particle layer that are partly embedded into the adhesive layer, and where the average reflectivity of the exposed granular particles is below 55 percent reflectivity on a standard reflectivity scale. The innovative reflectivity granular particle layer system that is securely bonded to concrete or shotcrete can be used along a wall, a floor, a ceiling, or along any structure which requires water or moisture proofing. The inventive high strength adhesive is along at least one edge of the sheet membrane, and could also be used to embed the reflectivity granular particle.

A resin composition contains a (A) thermoplastic component, a (B) thermosetting component, and a (C) inorganic filler, 5%-weight-reduction temperature of a hardened substance of the resin composition being 440 degrees C. or more.

The invention provides a PSA sheet having a PSA layer exhibiting superior light shielding. Provided is a PSA sheet comprising a PSA layer that includes a PSA polymer. Carbon black particles are dispersed in the PSA layer. The average particle size of the carbon black particles dispersed in the PSA layer is 300 nm or smaller. The average particle size is an average particle size determined on the basis of a number-based particle size distribution by TEM observation.

Provided is a pressure-sensitive adhesive sheet capable of allowing a small electronic part (e.g., a chip having a size of 50 μm/□ or less) to be temporarily fixed in a satisfactory manner and satisfactorily peeled. The pressure-sensitive adhesive sheet of the present invention includes a gas-generating layer configured to generate a gas by being irradiated with laser light, wherein a modulus of elasticity Er(gas) [unit: MPa] of the gas-generating layer measured by a nanoindentation method and a thickness h(gas) [unit: μm] thereof satisfy the following expression (1):

Log(Er(gas)×10.sup.6)≥8.01×h(gas).sup.−0.116  (1).

In one embodiment, the pressure-sensitive adhesive sheet has a transmittance of from 0% to 35% for light having a wavelength of 360 nm. In one embodiment, the pressure-sensitive adhesive sheet has a transmittance of from 10% to 100% for light having a wavelength of 380 nm.

A self-adhering roofing membrane may include a polymeric membrane. The roofing membrane may include a first adhesive layer disposed on a major surface of the polymeric membrane. The first adhesive layer may include one or both of a hot melt adhesive and a butyl rubber-based adhesive. The roofing membrane may include a UV curable adhesive layer disposed on the first adhesive layer. The UV curable adhesive layer may have a thickness of less than about 4 mils.

A sealing device has a waterproofing layer, a functional layer, and an adhesive layer coated on and at least partially covering the first major surface of the waterproofing layer opposite the side of the functional layer. Also, a method produces a sealing device, a method waterproofs a substrate, and the use of the sealing device seals lapped joints formed between overlapping portions of waterproofing membranes and patches breaches in waterproofing membranes.
