How to Use Murakami SP 9500:

Mesh Preparation:

1. Apply mesh degreaser to both sides of the mesh, creating a lather.
2. Thoroughly rinse the screen and frame with water, then allow it to dry completely.

Coating Process:

1. Place the screen on a stable surface, slightly tilted upwards.
2. Pour a sufficient amount of Murakami SP 9500 Dual Cure Emulsion into the scoop coater.
3. Hold the scoop coater at a slight angle and apply the emulsion to the print side of the screen.
4. Ensure even and consistent coverage with a smooth, steady pass.
5. Flip the screen and use the scoop coater to apply one coat of emulsion to the squeegee side.
6. For a thicker stencil, apply additional coats to the squeegee side while the emulsion is wet.
7. Note: Applying one coat on each side of SP 9500 is equivalent to four coats of wet-on-wet application with standard diazo-based emulsions.
8. Allow the emulsion to fully dry between coats. Drying: Place the screen in a clean and dark drying cabinet. Ensure the screens are completely level with the print side facing down. Maintain the cabinet’s temperature below 110 degrees Fahrenheit (43 degrees Celsius). Allow the emulsion to thoroughly dry before proceeding.

Film Positive Placement:

1. Position the film positive on the shirt side of the screen, ensuring it makes contact with the emulsion.
2. Expose the screen using your exposure unit. Exposure times may vary based on your light source and coating methods.
3. Precise exposure is crucial for optimal results. Utilize an exposure calculator to determine the ideal exposure time.
4. Developing: Gently spray both sides of the screen with lukewarm water.
5. Wait approximately 30 seconds. Gently wash the print side until the image becomes fully visible.
6. Rinse both sides of the screen thoroughly with water.
7. Ensure the screen is entirely dry before moving on to the printing stage.

Printing:

1. With the properly exposed and developed screen, you’re now ready for the screen printing process.

Final Steps:

1. Handle the screen and emulsion in a light-safe environment to prevent premature exposure. Store Murakami SP 9500 Dual Cure Emulsion in a cool, dry area to maintain its quality.
