The present invention relates to a backing layer comprising a barrier coating layer comprising an inorganic filler and a polymer having a glass transition temperature of ?35? C. to +15? C.

The present invention relates to a laminate structure comprising an adhesive polymeric interlayer (API) that comprises discrete zones. Such discrete zones are located at the interface of the API and the glass substrate. Generally, the discrete zones comprise two sets of discrete zones, debonding and adhesive. These zones allow for a unique combination of modified API-glass debonding, laminate toughness, and laminate durability. Various spatial patterns and densities of debonding are described, as well as the resulting material properties.

A UV release tape includes a substrate layer, a UV release layer, and a separation layer. The UV release layer is disposed between the substrate layer and the separation layer. A material of the substrate layer includes a polyvinyl chloride, a plasticizer, and a metal salt compound. Relative to 100 phr of the polyvinyl chloride, an amount of the metal salt compound ranges from 1 phr to 8 phr. The metal salt compound includes a calcium salt compound and a zinc salt compound. A peeling strength of the UV release layer toward a silicon wafer is higher than 10 N/in. After being exposed to UV light, the peeling strength of the UV release layer toward the silicon wafer is lower than 0.3 N/in.

A polymeric tape comprises a facestock extending lengthwise, the facestock including a polymer. An adhesive layer is on a first surface of the facestock. Tear-cuts are formed into at least one longitudinal edge of the facestock and extending inwardly, the tear-cuts being provided all along the at least one longitudinal edge of the facestock.

A roof system comprising a roof substrate, a first membrane including first and second opposed planar surfaces, and a second membrane including opposed first and second planar surfaces, where said second membrane is adhered to said roof substrate through an adhesive disposed on said roof-substrate contacting portion of the first membrane, and where said second membrane is adhered to said first membrane through said adhesive disposed on a lap portion of said second membrane.

Provided is a PSA sheet capable of providing greater air release properties. The present invention provides a release-linered PSA sheet comprising a PSA sheet and a release liner covering an adhesive face of the PSA sheet. The PSA sheet has a coating layer that partially forms the adhesive face. The release liner has an arithmetic average roughness of 0.1 m or greater on the PSA sheet side surface.

Disclosed is a granular adhesive comprising adhesive particles, wherein the adhesive particles include a core containing an adhesive composition, a shell covering the core, and an enclosed gas, and the shell includes solid particles.

A temporary adhesive material for a wafer processing, used for temporarily bonding a support and a wafer having a circuit-forming front surface and a back surface to be processed, contains a complex temporary adhesive material layer having a three-layered structure that includes a first temporary adhesive layer composed of a non-silicone thermoplastic resin layer capable of releasably adhering to the front surface of the wafer, a second temporary adhesive layer composed of a thermosetting siloxane polymer layer laminated on the first temporary adhesive layer, and a third temporary adhesive layer composed of a thermosetting siloxane-modified polymer layer laminated on the second temporary adhesive layer and capable of releasably adhering to the support. A wafer processing laminate and temporary adhesive material for a wafer processing facilitate temporary adhesion and separation, have excellent CVD resistance, and can increase productivity of thin wafers, and a method manufactures a thin wafer using the same.

The invention relates to a method for bonding an adhesive layer (3) with a first joining part (4), in which a first surface (3a) of the adhesive layer (3) is applied to a first joining part surface (4a) and the first surface (3a) of the adhesive layer (3) and/or the first joining part surface (4a) is/are subjected to partial area pre-treatment, a separating force in pre-treated areas (6) between the first joining part surface (4a) and the first surface (3a) of the adhesive layer (3) is increased thereby, and on peeling of the adhesive layer (3) from the first joining part surface (4a), the adhesive layer (3) separates cohesively in pre-treated areas (6) and the first surface (3a) of the adhesive layer (3) separates adhesively from the first joining part surface (4a) is untreated areas (7).

An advanced hair removal and sculpting apparatus and method is disclosed, which includes specially designed hair removing strips, an applicator stick, and an applicator stick system. The hair removing strips are a central innovation of the present apparatus, tailored in various sizes and shapes for different body contours. These strips are constructed from skin-friendly materials with a unique pressure-sensitive adhesive layer, capable of effectively removing hair from body areas with minimal discomfort. The applicator stick features an adhesive coated tip at one end that comprises a unique pressure-sensitive adhesive. This applicator stick is adept at precisely removing hair, particularly nose, ear, and eyebrow hairs. The adhesive formulation of the present invention balances strong hair adherence with gentle removal, incorporating soothing agents for skin care. This apparatus offers a comprehensive solution for both precision sculpting and efficient hair removal across the body and face, aligning with modern grooming needs.
