Characteristic

Low tensile modulus Gel (Elasticiy:1.0E+02～1.0E+03 Pa）

• Pre-curing (less pre-Alignment)
• Reduce air bubble, follow steps, reduce stress.
  

Adding UV cure function.

• Reversible function gets dissipated by UV irradiation.
• Maintain uniformity, good addhesive strength, endurable reliability.
  

Spec

• Able to customize optical, physical performance based on requirement.

Application

High aspect ratio and make Flat film forming.

Lamination for various structures.

Sealing, Reinforcement, Overflow, and Flow Control

pre-Alignment.

Principle

Reversible Gel and Liquid by temperature.

• Heat up application provides several method.(Slit, Di coting, Jet dispense, and others.)
  

• Temperature change. (tensile modulus, viscosity)
  

　

Process	UV curing hot melt	Newtonian liquids
During application	Required for heating	No heating required
After application	Rapid viscosity increase & gelation by cooling	Liquid does not change
hape retention	Almost no fluidity due to gel condition	Overflow is occurred

• Reversible change (tensile modulus)
  

Several above features provide benefits as below.

• Able to make free and variety shapes.(3D, Sheet, High aspect.)
• Able to control overflow.
• Able to do de-assemble by heat. (repare, pre-Alignment.)
