ADHESIVE MEMBER, METHOD OF MANUFACTURING DISPLAY DEVICE INCLUDING FORMING THE ADHESIVE MEMBER, AND DISPLAY DEVICE MANUFACTURED THEREBY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18471044 titled 'ADHESIVE MEMBER, METHOD OF MANUFACTURING DISPLAY DEVICE INCLUDING FORMING THE ADHESIVE MEMBER, AND DISPLAY DEVICE MANUFACTURED THEREBY

The adhesive member described in the patent application is made from a resin composition containing a urethane (meth)acrylate oligomer, a polyfunctional (meth)acrylate monomer, and a photoinitiator.

  • The urethane (meth)acrylate oligomer in the adhesive member is present at a weight of 1 wt % or more and less than 10 wt %, while the polyfunctional (meth)acrylate monomer is present at a weight of 0.2 wt % or more and less than 2 wt %.
  • The adhesive member has a glass transition temperature of -10°C or more and less than 10°C, and a loss tangent (tan δ) at -40°C of 0.01 or more and less than 0.3.
  • The adhesive member allows for easy rework at -40°C and exhibits excellent adhesion reliability during use.

Potential Applications: The adhesive member can be used in various industries such as automotive, electronics, and construction for bonding applications requiring easy rework and strong adhesion.

Problems Solved: This technology addresses the need for adhesives that can be easily reworked at low temperatures while maintaining high adhesion reliability.

Benefits: The adhesive member offers the convenience of easy rework at low temperatures without compromising on adhesion performance, leading to improved efficiency and reliability in bonding applications.

Commercial Applications: The technology can be utilized in the manufacturing of electronic devices, automotive components, and construction materials where reworkability and strong adhesion are essential for product quality and performance.

Questions about the technology: 1. How does the urethane (meth)acrylate oligomer contribute to the adhesive properties of the member? 2. What are the specific industries that can benefit the most from this adhesive technology?


Original Abstract Submitted

An adhesive member of may include a polymer derived from a resin composition including at least one urethane (meth)acrylate oligomer including two (meth)acryloyl groups per oligomer unit, at least one polyfunctional (meth)acrylate monomer including multiple (meth)acryloyl groups per monomer unit, and at least one photoinitiator. The weight of the urethane (meth)acrylate oligomer may be 1 wt % or more and less than 10 wt %, and the weight of the polyfunctional (meth)acrylate monomer may be 0.2 wt % or more and less than 2 wt %, based on a total weight of the resin composition. The glass transition temperature of the adhesive member may be −10° C. or more and less than 10° C., and the loss tangent (tan δ) of the adhesive member at −40° C. may be 0.01 or more and less than 0.3. Accordingly, the adhesive member may undergo easy rework at −40° C. and show excellent or suitable adhesion reliability during use.
