SAATItex PHU-HRX

DIRECTIONS FOR USE
Handle under yellow safelight or low wattage tungsten lights. Avoid exposure to daylight, quartz/halogen lamps, cool white fluorescent lamps or discharge lamps.

SENSITIZING & MIXING
Emulsion is presensitized during production, no mixing required.

MESH PREPARATION & DEGREASING
Degrease and abrade new mesh with SAATI Direct Prep 1 in order to optimize stencil adhesion; dry and store the screen in a dust free, dry environment prior to coating. For more applications, thoroughly degrease the mesh prior to use with SAATI Direct Prep 2.

COATING
By Hand: Using a high quality scoop coater or coating trough, apply one or two coats to the substrate side of the screen, followed by one or two coats on the squeegee side.
With Automatic Coating Machines: For general purpose printing use 1+2 coating program, with one coat on substrate side and two coats on squeegee side of screen.

DRYING & STORAGE
Thoroughly dry the coated screen at a maximum temperature of 104°F (40°C) in a dust free, dark or yellow light area, with the substrate side facing down to optimize stencil quality. Coated screens should be stored in a dust free, dry, safelight environment.

EXPOSING
With film positive - Contact the emulsion side of the positive with the substrate side of the screen and secure in position before placing the screen in a suitable vacuum frame. Many variables can affect exposure time. To confirm correct exposure, adhere a SAATI 21-Step Sensitivity Guide to the perimeter of the emulsion outside of the art, but in an area that will be completely exposed. A correct exposure level is indicated by holding 7 solid steps on the sensitivity guide once developing is concluded.
With Direct to Screen Ink or Wax Mask, or CTS Exposure - To confirm correct exposure, adhere a SAATI 21-Step Sensitivity Guide to the perimeter of the emulsion, outside of the art but in an area of the emulsion that will be completely exposed. A correct exposure level is indicated by holding 6 solid steps on the sensitivity guide once developing is concluded.

DEVELOPING
Wet both sides of the screen with a strong, finely divided spray of water and continue washing out until all image areas are fully open. Rinse both sides of the screen and dry thoroughly before use. A properly exposed and developed screen will not leave residues on the squeegee side.

POST EXPOSING
Post expose the developed stencil with daylight or an exposure lamp to produce a more water and/or solvent resistant stencil. This is particularly effective process to improve water resistance.

RECLAIMING
Manual Process - Remove all ink residues immediately after printing with SAATI Remove IR26. Remove stencil with SAATI Remove ER6 (concentrate) diluted in dip tank, or for spray & brush use Remove ER2 (diluted), or Remove ER5. For stains use a second application of SAATI Remove IR26, and for stubborn ghost images, use SAATI Remove HR9 followed by a pressure washer.
Automatic Machine Process - Remove all ink residues immediately after printing with SAATI Remove IR29. Remove stencil with SAATI Remove ER10, ER13, or ER25 (concentrates). For stains use a second application of Remove IR29, and for stubborn ghost images, use SAATI Remove HR9 followed by a pressure washer.

STORAGE
When sealed in the original container and stored in cool conditions, SAATI products will maintain their original properties for one year from the date of production.
