Exhibit at SID Vehicle Display Detroit

Bando Chemical Industries, Ltd (Kobe, Japan) will be exhibiting at SID Vehicle Display Detroit at Burton Manor Conference Center, Livonia, MI, (U.S.A.) Sep. 26-27, 2017. At this exhibition, we will introduce and demonstrate our Poly-Urethane base super thick OCA which improved the difficulties of conventional OCA when used for Direct-bonding^{※１ .}

※1 Direct-bonding is a process of laminating Cover glass and LC display by Optical Clear Adhesives (OCA) for better visibility, and higher durability even for outside use.

Polyurethane OCA provides new solutions
for direct bonding

Summary

1. BANDO’s Polyurethane OCA provides new solution for direct bonding. It overcomes various challenges where existing materials such as Acrylic and Silicone have been struggling to address, typically bonding “on displays with bezel” and “on curved cover plate”.

2. BANDO produces very thick OCA up to 2 mm, which is soft enough to transform its shape to fit into the gap and level difference caused by a bezel. It is soft enough to absorb the difference of thermal expansion between glass and plastic cover plate, which are often used for curved display.

3. After thermal curing, adhesion becomes strong enough to suppress the outgas from the plastic.

Comparison of key features among different bonding materials (OCA, OCR)

Advantages of “on bezel” bonding over “in bezel” bonding

Curved shape display

Curved shape display requires :

- Adhesion power to bear residual stress
- Adhesion power to suppress outgas from plastic cover material
- Softness to absorb the difference of thermal expansion between glass and plastic

BANDO’s OCA provides the solution

- By a thermal curing process to give enhanced adhesion
- By natural softness of Polyurethane
- By easy “reworkability” before curing
