GALLON - This is a blue dual-cure direct emulsion for printing UV-cured, plastisol, solvent-based and water-based inks which is excellent for print definition on any mesh. Upon drying, stencils lack the typical tackiness of dual-cure emulsion with 39% solids content. Available in gallon containers.
Applications: General industrial and display graphics, compact disc, half-tone printing.
Characteristics: Dual-cure direct emulsion for printing UV-cured, plastisol, solvent-based and water-based inks. Excellent print definition on any mesh. 39% solids content Features/Benefits. Low friction stencil surface prints fine details cleanly and improves 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 Prepare Diazo as per instructions on the bottle. Add the entire contents to the emulsion and mix thoroughly until a smooth consistency is obtained. Write the date of sensitizing on the label and then cover the sensitized emulsion and let stand for a few hours to enable air bubbles to escape. Store sensitized emulsion in cool conditions and use within one month for best results.
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.
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.
