Sta-Sharp S3S Knifecut Film - Water Resistant

Tech Data Sheet imageTech Data Sheet- Spanish


A year ago we announced a VOC (volatile organic compound)-free
version of Sta-Sharp S3S, our solvent-adhered knifecut stencil
film, as well as a VOC-free version of Sta-Sharp Adhering Liquid.
This breakthrough chemistry made it possible for an aqueouscoated
film to resist aqueous inks.

Unfortunately, we found that after reformulated S3S film ages, it
cannot be dissolved sufficiently by the reformulated adhering
liquid to be adhered securely to screen mesh. This is especially
so if the screen mesh is coarse or has not been prepared
thoroughly—instances when the original formulation was
essentially failure-proof.

"We have formulated a new VOC-containing adhering liquid to be used with reformulated, VOC-free S3S film. It is called DP-4143 and is being field tested. Results are promising, although the new adherent requires 15-30 minutes of drying, depending on the ambient humidity. We no longer recommend the use of reformulated Sta-Sharp Adhering Liquid ("QSS-G"--part number for quarts; "GSS-G"--part number for gallons) with reformulated S3S film.
