IMPACT RESISTANT GLASS SCREEN PROTECTOR

Disclosed is a multi-layer screen protector for a display of an electronic device. The screen protector may include a glass exterior surface for tactile response, an optically clear anti-explosion adhesive to contain broken glass from the protector or the display, and a TPU layer to provide impact resistance. The screen protector may be flat or curved.

POSITIONABLE AND REPOSITIONABLE ADHESIVE ARTICLES FOR STRETCH RELEASE REMOVAL

The present disclosure relates to adhesive article that include a stretch releasable adhesive and topographical, engineered elements on, within, or partially embedded in a surface of the adhesive. The engineered elements can act as spacers between the adhesive surface and the mounting surface to prevent full contact and wet out of the adhesive, whereby the article can be initially positioned or rotated by sliding the surface of the projections across the wall surface. Under certain conditions, the article may even be removed from the wall and placed at a new location without damage to the wall surface or the article. Once the location is selected, the separation created by the engineered elements can be overcome by applying sufficient pressure; the adhesive can contact and adhere more permanently to the wall. Thus, a stretch releasable adhesive articles of the present disclosure can move freely against the desired mounting surface, develop additional tack and holding power after sufficient pressure is applied.

Reusable Adhesive Device

ppA reusable adhesive device is shown and described. The reusable adhesive device includes a first material having a first adhesive located on a bottom side. An indicium which represents a food is located on the opposite side of the first material from the adhesive. The reusable adhesive device is capable of being placed on a dispenser. The dispenser will secure the reusable adhesive device to the dispenser. The dispenser will allow a length of material to he cut from the reusable adhesive device for use.

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.

PRESSURE-SENSITIVE ADHESIVE ARTICLES

Provided is an adhesive article which requires no separator and exhibits sufficient adhesive force without the need of any operation for adhesive-force development and in which the adhesive layer, even when in contact with itself, can be peeled off at the interface. The adhesive article includes an adhesive body including an adhesive layer, wherein the adhesive layer has a gel content of 5-70%, the adhesive article, through 7-day storage at 40 C., has a change in the gel content of the adhesive layer of 5% to 5%, and surface portions of the adhesive layer are in contact with each other.

Pleated, Waterproof Sealing Tape and Method of Use
20200407598 · 2020-12-31 ·

The present invention relates to a pleated sealing tape for providing a waterproof covering. The pleated sealing tape includes a flexible sheet made of a polymeric material and having a plurality of pleats extending from a first end of the sheet to an opposing end of the sheet. The pleated sealing tape also has a front surface and a rear surface, and the rear surface of the sheet includes a pressure-sensitive adhesive. When the sheet is applied to a surface, the sheet is configured to be removed by stretching the sheet in a direction transverse to the orientation of the plurality of pleats and subsequently peeling the sheet off of the surface.
