silver conductor dts-705-1
conductive paste for fine pattern
application of touch screen panel
product description
dts-705-1 is a one part, conductive paste designed primarily for the purpose of fine pattern in screen printing. it can be used with semi-automatic, and manual printers, and offers excellent residence time on the screen. the cured film has excellent electrical and mechanical properties with good adhesion to a variety surfaces(ito coated film).
processing procedures
application
before use, take paste out of the refrigerator, leave it in a room in the sealed state for approximately one hour, then use after mixing well.
the material may be applied by screen printing, a 400 or 500mesh screen with a 8-12um organic emulsion backing is recommended. use a hard silicone squeegee. screens can be cleaned with organic solvents such as 1st ethyl carbitol, 2nd ethanol or isopropyl alcohol.
dilute solution
ethyl carbitol acetate.(cas : 112-15-2)
curing
minimum cure is 130℃ for 30 minutes. cure time is only a guide. optimum conditions will vary depending upon application and will need to be determined experimentally.
