摘要:
A dimensionally stable floor covering comprises a tufted textile substrate and a reinforcement layer attached to the textile substrate. The reinforcement layer includes an adhesive backing compound and reinforcement fibers surrounded by the adhesive backing. The fibers may form a continuous layer on the back side of the floor covering or may be dispersed within the adhesive backing compound. The adhesive backing compound may be hot water-soluble to facilitate recycling of the floor covering. The floor covering may optionally include additional backing layers (including cushions) and may be used as a broadloom carpet, a carpet tile, or other modular floor covering products. Methods of manufacturing, installing, and recycling the present floor coverings are also provided.
摘要:
Adhesive compositions comprising one or more silicone/acrylate copolymers are described. Also described are various healthcare adhesive articles in sheet form which include a carrier sheet, a release coating applied to the carrier sheet, one or more regions of pressure sensitive adhesive adjacent the release coating, a flow control layer for promoting distribution of one or more adhesive debonding agents, and a substrate or facestock sheet removably disposed on the carrier sheet. The adhesive layer includes a pressure sensitive adhesive having a minority proportion of a silicone containing agent blended with one or more acrylic polymers. After application to a surface of interest, the adhesive strips can be easily removed by application of a debonding agent.
摘要:
A method for manufacturing a semiconductor device with a treated member, includes: subjecting an adhesive support having a substrate and an adhesive layer capable of increasing or decreasing in adhesiveness upon irradiation with an actinic ray or radiation to pattern exposure of the adhesive layer to provide a high adhesive region and a low adhesive region in the adhesive layer, adhering a first surface of a to-be-treated member to the adhesive layer of the adhesive support, applying a mechanical or chemical treatment to a second surface different from the first surface of the to-be-treated member to obtain a treated member, and detaching the first surface of the treated member from the adhesive layer of the adhesive support.
摘要:
A method for manufacturing a semiconductor device with a treated member, includes: subjecting an adhesive support(100, 110, 120) having a substrate(12) and an adhesive layer(11, 21, 31) capable of increasing or decreasing in adhesiveness upon irradiation with an actinic ray, radiation or heat to irradiation of the adhesive layer with an actinic ray, radiation or heat, adhering a first surface(61a) of a to-be-treated member(60) to the adhesive layer of the adhesive support, applying a mechanical or chemical treatment to a second surface(61b) different from the first surface of the to-be-treated member to obtain a treated member(60'), and detaching a first surface of the treated member from the adhesive layer of the adhesive support, wherein the irradiation of the adhesive layer with an actinic ray, radiation or heat is conducted so that adhesiveness decreases toward an outer surface from an inner surface on the substrate side of the adhesive layer.
摘要:
An improved semiconductor wafer debonding system, method, and apparatus, including a stress-free means for multi-axis debonding utilizing a specialized tool or fixture having at least one ultrasonic transducer.
摘要:
A debondable adhesive article having two opposing sides is provided that includes a shape- memory polymer sheet in its temporary strained shape that includes a plurality of slits therein and a first adhesive on one opposing side of the polymer sheet and a second adhesive on the other opposing side of the polymer sheet. The provided article, optionally, includes a first substrate in contact with the first adhesive and a second substrate in contact with the second adhesive. The article can be debonded by heating the article to a temperature equal to or greater than a transition temperature for the shape-memory polymer sheet.
