The present invention discloses flip-chip bonding method using an anisotropic adhesive polymer. The method includes applying an adhesive polymer solution containing metal particles dispersed therein onto a circuit substrate to form an adhesive polymer layer such that the adhesive polymer layer covers the metal particles; drying the adhesive polymer layer; and positioning an electronic element to be electrically connected to the circuit substrate on the dried adhesive polymer layer and causing dewetting of the polymer from the metal particles.

A method for producing an optical silicone assembly is disclosed. The method comprises the steps of: i) treating a surface of a substrate with an optically clear silicone adhesive composition; ii) placing the substrate obtained by step i) into a mold; iii-a) injecting an optically clear moldable silicone composition into the mold, and/or iii-b) overmolding the optically clear moldable silicone composition onto the substrate; and then iv) heating the optically clear moldable silicone composition to form the optical silicone assembly. The optical silicone assembly produced by the method of this disclosure is characterized by excellent adhesion of an optical silicone product to various types of substrates.

A patch is provided and described that can be used with the installation of a cured-in-place structural liner in a conduit when the conduit has protrusions into the conduit. The patch is made with similar material to the liner, or felt, and is impregnated with epoxy. The patch may be shaped to more closely match the anticipated curve of the outer surface of the liner. Tools for the installation of the patches, a method of use, and tools for measuring the quality of the installation of the patch before the installation of the structural liner, are also described.

A method for curing adhesive during assembly of glass syringes, including: dispensing adhesive onto a glass syringe; and curing the adhesive using a UV LED line array. The method may include one or both of pre-curing the adhesive using a UV LED spot and heating at least one of the glass barrel, needle and adhesive at one or more points during the method. A system for curing an adhesive during assembly of a glass syringe, the system including: a dispensing station for dispensing the adhesive onto a glass barrel and needle; a pre-curing station for pre-curing the adhesive; a curing station for curing the adhesive; and at least one infrared heater for heating at least one of the glass barrel, needle and adhesive at one or more points in the system. The glass syringe may be operated on by a subset of the stations in the system.

A filtration device (10A, 10B, 10C) comprising one or more filtration media (20) secured by one or more activatable adhesive layers (22). A method of forming a filtration device, including: (a) forming the one or more adhesive layers into a desired shape; (b) activating the one or more adhesive layers; (c) securing the one or more filtration media to the one or more adhesive layers; and (d) curing the one or more adhesive layers.

With present invention, as disclosed in U.S. Provisional Patent Application No. 63/350,647 filed on Jun. 9, 2022, we describe a new tempered glass for touch and non-touch screens. Unlike existing protecting films, our development offers increased flexibility, reusability, and an easier application process. The advantages described above result in the reduction of the tedious work associated with the installation of a screen protector. Thus, allowing the users of the electronic devices the opportunity to install them themselves without the help of third parties. Our newly developed film includes a protective film, a tempered glass screen protector with electroplating AF coating, an adhesive layer, and a release liner. It also includes specially made stickers to clean the surface before application and the adhesive layer of the protector for re-application. The proposed protector can also be cleaned using regular soap, water, paper, or a towel cloth to remove dust and be re-utilized.

Various opacifying adhesive compositions are described. The adhesives exhibit relatively high levels of opacity in wet conditions while maintaining acceptable adhesive properties. Also described are label assemblies and labeled containers using such adhesives. Related methods of use and preparation are also described.

A UV patch for repairing inanimate objects. The UV patch includes a fibrous material. The UV patch also includes a UV activated hardening material. The UV activated hardening material is impregnated within the fibrous material and hardens when exposed to UV radiation.

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.

Provided is a laminate with a glass layer having excellent surface hardness and impact resistance. A laminate with a glass layer of the present invention includes a glass layer, a first pressure-sensitive adhesive layer, an impact absorbing layer, and a second pressure-sensitive adhesive layer in the stated order. The laminate with a glass layer has a pencil hardness of 5 H or more, and according to the laminate with a glass layer, an impact amount S.sub.A detected when a stainless-steel ball having a weight of 10 g and a diameter of 13 mm is vertically dropped from a height of 40 cm onto a surface of an impact detection sensor and an impact amount S.sub.B detected when the stainless-steel ball is vertically dropped from a height of 40 cm onto the laminate with a glass layer placed on the surface of the impact detection sensor satisfy the following relationship: {(S.sub.A−S.sub.B)/S.sub.A}×100≥25(%).
