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.
