SaatiChem Graphic PU Emulsion - Gallon
GALLON - This is a blue photopolymer emulsion with a wider exposure latitude and lower cost for printing UV-cured, plastisol, solvent-based, and discharge inks. Good for water based inks when post exposed. Exposes 4 times faster than most dual cure emulsions.
Applications: General graphic printing.
Characteristics: 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. Easy to reclaim features/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.
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 & 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 more applications, thoroughly degrease the mesh prior to use with Saati Chemicals Direct Prep 2.
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.
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. Developing Wet both sides of the screen with a 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.
Post exposing: Post expose with daylight or exposure lamp to produce a more water-resistance stencil.
Reclaiming: Remove all ink residues immediately after printing with either Saati Chemicals Ink Remover IR4 or IR5. Remove stencil with Saati Chemicals Emulsion Remover ER2. For stains and ghost images, use Saati Chemicals Haze Remove HR5 followed by a pressure washer.
