4021-38
|
High transmittance,
high index of refraction, good weatherability,
won’t turn to be yellow for a long time; Neutral formula, anti-corrosion ITO
coating; Superior electric performance, won’t influence the operation speed
of touch screen for a long time, easy for repairing with low hardness;
Various viscosity choice, suitable for automation equipment production and
manual joint, easy to apply; Have a good adhesive strength to ITO glass, and
PET material, etc. Typical applications in capacitive, resistive touch screen
joint industry.

Notes
|
1.
Storage under 8℃－25℃, in the dark, sealing, ventilation, cool
conditions, and far away from children.
2.
Keep air
ventilation when using, and take the safe protection measures, such as don't
use your skin to touch the resin directly or longly.

Remarks
|
1.)
Viscosity standard： Tested
under 25℃±0.5, by using the container with diameter
6-7cm, and height 10cm.
2.) The setting
time of above items were tested under the condition of glass bond glass with 40w and light intensity is under
7.5mW/cm2. 3.)
Above tensile & shear strength data tested when glass bond glass, glass
bond crystal.
4.)
Other test parameters are tested on the basis of the national testing.
