Described herein are methods of forming uncured sealant assemblies and also methods of forming seals between various parts using such assemblies. In some examples, an uncured sealant assembly comprises two protective layers and an uncured sealant layer, disposed in between. The uncured sealant assembly is stored and provided at a cure-inhibiting temperature, selected to minimize the curing rate of the uncured sealant layer. The size and the shape of the uncured sealant layer are specifically selected to ensure the complete coverage of the faying surfaces, filling of all gaps and voids between the faying surfaces, and controlling the shape and size of uncured sealant squeeze out between the faying surfaces. In some examples, the size and shape of the uncured sealant layer maybe be specifically selected to have no uncured sealant squeeze out between parts.

The present invention relates to an adhesive sheet. As the adhesive sheet of one embodiment of the present invention retains the properties of conventional adhesive sheet, such as excellent adhesion and durability in high temperature and humidity environment, it can be utilized for manufacturing large-scale electrodes at low prices, and the electrodes manufactured above can be used for various applications such as solar cell, display, and touch panel.

Adhesives for use in polishing pads in chemical mechanical planarization (CMP) applications are described. The adhesives include an adhesive component and exhibit particular properties. Also described are transfer tapes containing the adhesives, CMP pads utilizing the adhesives, and related methods of use.

This curable fluoropolyether adhesive composition is capable of providing a cured product having good light transmittance and high adhesiveness to glass materials.

The present disclosure provides an adhesive composition including a silicone-based adhesive and cellulose nanocrystals dispersed in the silicone-based adhesive. The present disclosure also provides an article including a substrate and a layer of the adhesive composition adhered to the substrate. Further, the present disclosure provides a method of making an adhesive composition. The method comprises mixing cellulose nanocrystals in a silicone-based adhesive to disperse the cellulose nanocrystals. The present disclosure additionally provides a method of making an article including disposing a layer of the adhesive composition on a substrate. The presence of the cellulose nanocrystals advantageously increases the water uptake capacity of the silicone-based adhesive while maintaining acceptable adhesive performance.
