Textil PHU – Photopolymer Emulsion




Textil PHU – Photopolymer Emulsion

One Gallon


All purpose solvent and water resistant photoemulsion.


  • One-part, pure photopolymer emulsion, no mixing required
  • 45% solids content and medium viscosity, easy coating on wide range of mesh
  • Fast exposure, approximately 8X faster than typical two part emulsion
  • Can be used with plastisol, water-based and discharge inks
  • Solvent resistant and easy to reclaim


  • 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 and does not require mixing.
  • Mesh Preparation & Degreasing
  • Degrease and abrade new mesh with Saati Chemicals Direct Prep 1 in order to optimize stencil adhesion; dry and store the screen in a dust free, dry environment prior to coating. For subsequent applications, thoroughly degrease the mesh prior to use with Saati Chemicals Direct Prep 2 or 3.


  • Using a high quality scoop coater or coating through, 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.


  • 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.


  • 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 expose with sun light or exposure lamp to produce a more water-resistant stencil.
