Saati Graphic PU Photopolymer Emulsion – Works with Plastisol Inks
- Blue pure photopolymer emulsion
- Resistant to UV-cured, plastisol and solvent-based ink. Water resistant when post-exposed
- High solids content and medium viscosity for excellent print definition on any mesh
- Exposes 4 times faster than diazo or dual-cure emulsions with no mixing require
- Easy to reclaim
Features and Benefits:
- Pre-sensitized with no mixing required, long shelf life with consistent performance
- SBQ technology, exposes 4 times faster than two part emulsions and leaves no diazo stains
- Low friction stencil surface for improved durability when used with abrasive inks
- NOTE: Saati chemicals drop ship from the manufacturer in Fountain Inn, SC. Please allow 1-2 additional business days for processing and expect standard ground transit.
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 and does not require mixing.
Mesh Preparation & Degreasing
- Degrease and abrade new mesh in order to optimize stencil adhesion; dry and store the screen in a dust free, dry environment prior to coating.
- 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 Exposing Post expose with daylight or exposure lamp to produce a more water-resistance stencil.
- Remove all ink residues immediately after printing with an appropriate solvent. Remove stencil with Saatichem Remove ER1, ER2, ER4, ER5 or ER10 and a pressure washer. For stains and ghost images, use Saatichem Remove HR3 followed by a pressure washer.
Health & Safety
- Before using, refer to appropriate material safety data sheets.
