An acoustical ceiling panel including a first layer having a first major surface opposite a second major surface and a side surface extending therebetween, a second layer having a first major surface opposite a second major surface and a side surface extending therebetween, and a sealing layer having a first major surface opposite a second major surface and a side surface extending therebetween. The sealing layer may be positioned between the first major surface of the first layer and the second major surface of the second layer. The side surface of the sealing layer may extend beyond the side surface of the first layer and the side surface of the second layer.

ADHESIVE ARTICLES PERMITTING DAMAGE FREE REMOVAL
20210171805 · 2021-06-10 ·

The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

CURABLE RESIN COMPOSITION, COMPOSITE MEMBER, AND PRODUCTION METHOD THEREFOR

Provided are a curable resin composition having high durability and adherence to a base material such as a metal, a molded composite member formed by coating the base material with the curable resin composition and performing resin molding, and a production method for the same. The curable resin composition contains a polyamide-based resin, a blocked polyisocyanate, and an epoxy compound, and the polyamide-based resin has an amino group concentration from 20 to 300 mmol/kg, and has a water absorption of 1 mass % or less determined by a water absorption test specified by ASTM D570. The polyamide-based resin has a C.sub.8-18 alkylene chain and has a melting point from 160 to 250° C. Per 1 mol of amino groups of the polyamide-based resin, a proportion of isocyanate groups of the blocked polyisocyanate is from 1.5 to 5 mol, and a proportion of epoxy groups of the epoxy compound is from 0.1 to 0.8 mol.

ROOFING SYSTEM WITH CHANGEABLE DECORATIVE ELEMENTS
20210198891 · 2021-07-01 ·

A roofing system comprises layered construction panels, each having a bottom structural layer to provide strength and support. A performance layer overlies the structural layer and provides performance or functional characteristics such as water proofing, water shedding and/or impact resistance. An upper or decorative layer overlies the performance layer and provides aesthetic features or a decorative appearance for the roofing system. The decorative layer of the construction panels can be removed without damaging or affecting the performance layer. The appearance of a roof can thereby be changed at will without requiring that the entire roofing system be removed and replaced.

BEARINGS AND COMPONENTS THEREOF COMPRISING A HOT-MELT PRESSURE SENSITIVE ADHESIVE AND METHODS OF THEIR PREPARATION
20210284887 · 2021-09-16 ·

Methods of making bearings using pressure sensitive macromolecular adhesive polymers and pressure sensitive polymer compositions capable of integrating fluoropolymeric properties with a catechol-amine functionality to form an adhesive system that allows bonding between metallic substrates and fluoropolymers are disclosed. Also disclosed are core-shell polymeric particles comprised of a core and a shell comprising a thermoplastic polydopamine polymer that may be prepared as a colloidal suspension and used as a hot-melt pressure sensitive adhesive capable of binding low surface energy materials, such as polyolefins and fluoropolymers, to diverse materials including metals in making bearings and/or bearing components.

Composite nanofiber sheet

Examples described include composite nanofibers sheets that have been “infiltrated” with a polymer (i.e., the polymer has flowed past a surface of the nanofiber sheet and into at least some of spaces within the sheet defined by the nanofibers). An adhesive nanofiber tape is formed when the infiltrating polymer is an adhesive and the adhesive infiltrates the nanofiber sheet from a one major surface of the nanofiber sheet. In other described examples, some portions of nanofibers in the sheet have been conformally coated with at least one metal layer.

ELECTROMAGNETIC-WAVE ABSORBING SHEET
20210144890 · 2021-05-13 · ·

A so-called electromagnetic-wave interference type electromagnetic-wave absorbing sheet is realized which is low-cost and can favorably absorb electromagnetic waves in a desired frequency band that are incident not only in a direction perpendicular to the sheet surface, but also in a wide incidence angle range. The electromagnetic-wave absorbing sheet is formed by stacking an electric resistance film 1, a dielectric layer 2, and an electromagnetic-wave shielding layer 3. The electric resistance film is formed using a conductive organic polymer, and a surface electric resistance of the electric resistance film is 303 Q/sq or more and 350 Q/sq or less, or 415 Q/sq or more and 502 Q/sq or less.
