SaatiChem Textil PV

SaatiChem Textil PV is a red colored pure photopolymer direct emulsion resistant to plastisol ink, abrasion and humidity. Textil PV is a very fast emulsion. It exposes approximately 8 times faster than a standard dual cure emulsion like Merchmakr Dual Cure Emulsion or Saati Graphic HU42 emulsion.

Features/Benefits

  • Exposes 8x faster than a diazo or dual-cure emulsion
  • 42% solids content and medium viscosity for easy coating and good bridging on wide range of mesh counts
  • No mixing required and no diazo staining
  • Water resistant when post exposed

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 and Mixing

Emulsion is presensitized during production and does not require mixing.

Mesh Preparation and Degreasing

Degrease and abrade new mesh with Merchmakr Ghost-B-Gone Dehazer/Degreaser in order to optimize stencil adhesion; dry and store the screen in a dust free, dry environment prior to coating.

Coating

Using a high quality scoop coater, apply one or two coats to the substrate side of the screen, followed by one or two coats on the squeegee side. For a thicker stencil, apply additional coats to the squeegee side prior to drying. For a higher quality stencil with a minimal increase in stencil thickness, apply one or two additional coats to the substrate side of the screen after the initial coats have dried.

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

Ensure that all surfaces, emulsion, film and glass are free of dust to minimize pinholes. 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, such as lamp type and age, distance from lamp to screen, mesh type and coating thickness, can affect exposure time. Perform an exposure test with an exposure calculator to determinate correct exposure time for a complete cure.

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 with daylight or exposure lamp to produce a more water-resistance stencil.
