Acid-free pressure-sensitive adhesives for touch panels

Acid-free, resistant to whitening under heat and humidity, and ITO corrosion resistance

We affixed adhesive tape (50-μm adhesive layer) over a 10-μm height gradation caused by black ink and applied pressure over it with a 2-kg roller. After leaving it at 23ºC for 24 hours, we made visual observations.

Product number Features Non-volatile content
DAIKALAC 5021 Adhesion to glass (high adhesive strength) 30%
DAIKALAC 5022 Adhesion to glass (high adhesive strength) 30%

Acid-free, high solid content and human sebum-resistant

We affixed adhesive tape (50-μm adhesive layer) to a glass panel and applied pressure over it with a 2-kg roller. We then applied a sufficient amount of “artificial sebum solution (dyed red)” on the adhesive layer. After leaving it at 85ºC and 85% RH for 48 hours, we made visual observations.

Synthetic sebum solution: Formulation of triglyceride, isostearic acid and squalane

Product number Features Non-volatile content
P-7239A High solid content (Composition of DAIKALAC 5021) 60%
DAIKALAC 5250 Human sebum resistant 40%

Acid-free, resistance to plastic foaming under heat and humidity

We affixed adhesive tape (50-μm adhesive layer) to MR58 sheets (PC/PMMA by Mitsubishi Gas Chemical) and applied pressure over it with a 2-kg roller. After leaving them at 23ºC for 24 hours, then one at 85ºC and dry conditions and the other at 60ºC, 95% RH for 240 hours, we made visual observations.

Product number Features Non-volatile content
P-7240M Adding resistance to foaming under heat and humidity to plastic panels 40%
P-7240N Adding resistance to foaming under heat and humidity to plastic panels 40%
