Possibly the fastest exposing one-part available, PC 701 also has the highest known solids content of any emulsion! Testing has shown PC 701 to expose more than 3 times faster than other SBQ emulsions. With extremely high 51% solids, this SBQ emulsion allows you to use minimal coatings and create high-density stencils of 400+ microns, replacing more expensive capillary films. It offers textile printers excellent resistance to plastisol ink, easy reclaimability and an extended shelf life.

Applications;

PC-701 was developed for use with textile using plastisol ink and it is also compatible with solvent, UV, and water-based inks. 

Data Facts:

Blue in color, this SBQ photopolymer emulsion offers 51% sensitized solids and 11,000 CPS sensitized viscosity. Excellent for solvent, plastisol, UV, and still offering some water resistance.  PC-701 does not need to be sensitized   and should last up to 1 year at room temperature. PC-701 will work well with mesh counts above 74 or higher.

Exposure Time Reference:

When using a 5-KW Metal Halide Exposure lamp on mesh counts from 80 to 110 as a guide set your exposure time between 20-30 seconds.  On mesh counts of 125 to 230 allow 15 to 20 seconds exposure, and for mesh counts of 300 or more allow 10 to 15 seconds for exposure. Remenber, these exposure settings should only be used as a guide since exposure time will vary depending on equipment used, lamp life, type of emulsion, and applied coatings.

Coating Sequence:

It is not recommended to finish the last coating on the print side of the screen.  Finish the last coating on the squeege side.  If the coating ends on the print side, the E.O.M. thickness will decrease and go thinner on the print side.  This will cause premature stencil breakdown and poor ink deposit.

Resolution and Hardness:

Some printers do underexpose the screen to have details of images resolved on the screen.  Unless the number of printing impressions is very low, underexposed screens with poor hardness will cause many problems in the printing process, such as premature breakdown, more fish eyes, and pinholes, locking up emulsions with inks, ink cleaners, or other chemicals.  It is important therefore, to locate and standardize a proper exposure time and a good hardness scale by mesh count and coating profiles.
