Photoresist employs optimized coating rheology.

Press Release Summary:




Offering 24-48 hr of stackability, Photoposit(TM) SN 68V Photoresist exhibits resistance to mechanical and handling damage. It also exhibits resolution capability of 25 micron lines and spaces, while minimal foaming characteristics can eliminate need for antifoam addition to developer. Able to be used in manual and automatic exposure equipment, product is resistant to acid-based etchants and optimized for use on vertical double-sided roller coaters.
