20220403220 · 2022-12-22 ·

The present disclosure generally relates to a stretchable anti-fogging tape (SAT) that can be applied to diverse transparent materials with varied curvatures for persistent fogging prevention. The SAT comprises three synergistically-combined transparent layers: i) a stretchable middle layer with high elastic recovery to keep transparent materials tightly bound; ii) an anti-fogging top layer to impart hydrophilicity to transparent materials; and iii) an adhesive bottom layer to form robust yet reversible adhesion between transparent materials and SATs. The SAT can be configured to have water condensate form a predominantly continuous film thereon in response to a high humidity environment At least two applications are demonstrated, including the SAT-adhered eyeglasses and goggles for clear fog-free vision, and the SAT-adhered condensation cover for efficient solar-powered freshwater production.

PRESSURE-SENSITIVE ADHESIVE COMPOUNDS, AND SELF-ADHESIVE PRODUCTS AND COMPOSITES COMPRISING THE LATTER

The present invention relates to a foamed pressure-sensitive adhesive compound on the basis of aromatic polyvinyl-polydiene block copolymers, in particular for double-sided self-adhesive strips, containing a) 39.8 wt. % to 51.8 wt. % of an elastomer component, b) 35.0 wt. % to 58.0 wt % of an adhesive resin component, c) 2.0 wt. % to 15.0 wt. % of a plasticizer component, d) 0.0 wt. % to 18.0 wt. % of further additives and e) microballoons, the microballoons being at least partly expanded.

Protective film

A protective film 10 of the present invention includes a base material layer and a pressure sensitive adhesive layer, and is used by being attached to a resin substrate 21 at the time of performing heat bending on the resin substrate 21. The pressure sensitive adhesive layer contains a polyolefin having a melting point of lower than 125° C. The base material layer has a first layer which contains a polyolefin having a melting point of 150° C. or higher, and a second layer which contains an adhesive resin. In a case of heating the protective film 100 having such a configuration, in a state of being interposed between two attaching substrates which are formed of polycarbonate, at 145° C. for 30 minutes, peeling off one attaching substrate on the side of the pressure sensitive adhesive layer at 25° C., and then viewing a surface of the one attaching substrate in a plan view, a residual ratio of an area where the pressure sensitive adhesive layer remains is 5% or less.

20220363954 · 2022-11-17 ·

A resin composition for temporary fixing of a support for substrate conveyance to an organic substrate, the resin composition containing a thermoplastic resin, a thermosetting resin, and an inorganic filler. When the resin composition is formed into a film that is then heated for 30 minutes at 130° C. and for 2 hours at 170° C., the film obtains an elastic modulus of 350 to 550 MPa at 25° C.

REPOSITIONABLE ADHESIVE ARTICLES FOR STRETCH RELEASE REMOVAL

The present disclosure relates to adhesive article that include a first, stretch releasable adhesive and patterned adhesive elements on, within, or partially embedded in a surface of the adhesive. The adhesive elements can act as spacers between the adhesive surface and the mounting surface to prevent full contact and wet out of the first adhesive, whereby the article can be removed from the wall and placed at a new location without damage to the wall surface or the article. Once the final location is selected, the separation created by the engineered elements can be overcome by applying sufficient pressure; the first adhesive can contact and adhere more permanently to the wall. Thus, a stretch releasable adhesive articles of the present disclosure can move freely relative to the desired mounting surface, while developing additional tack and holding power after sufficient pressure is applied.
