SaatiChem Textil PC Blue Emulsion Quart

by Saati

Quart - A durable and fast photopolymer pre-sensitized emulsion. Blue in color. Requires no mixing! Exposes approximately 8 times faster than standard diazo emulsions. Perfectly resistant to plastisol inks. Resistant to water based and discharge inks when post exposed. Very easy to reclaim. Available in gallon containers.

Applications: Garment printing with plastisol ink.

Characteristics:‹ Blue one part pure photopolymer emulsion resistant to plastisol ink, abrasion and humidity.‹ Exposes 8X faster than typical two part emulsions features/benefits.‹ 50% solids content and medium viscosity for fast build up and good bridging on wide range of mesh counts.‹ No mixing required and no diazo staining of mesh ‹ Water resistant when post exposed and can be used to print water based inks and adhesives.

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. 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 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.

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.
