Sign & Graphics SBQ Screen print Photo Emulsion
Premium Purple Graphic Fast Exposing High Definition Emulsion

Product Description 
Sign & Graphic SBQ is a pure photopolymer emulsion utilizing SBQ technology engineered for graphic application. The viscosity allows for good stencil control on high mesh counts.

CBX-9000 is excellent for U.V. printing with the ability to print halftones exceeding 100 DPI. Emulsion has excellent resistance to strong solvents, also works with plastisol.

Forty eight percent solids leads to excellent edge definition while still allowing for easy reclaim.

Extremely reactive photopolymer emulsion allows for fast exposure times.

Mesh Preparation: 

It is very important to remove all contamination, residual inks, cleaning chemistry, or general dirt and dust. 

SCP708 Haze Remover will remove residual ink and/or emulsion.

SCP623 Screen Degreaser will help eliminate any further contaminants. Completely dry the screen before coating.

Coating: Use a clean dry coating trough that has a nick free surface for smooth coating.

•  Apply one or two coats of emulsion to the print side. Rotate the frame 180 degrees and apply one or two coats of emulsion to the squeegee side.

•  Additional coats may be added to the print side if thicker stencils are required.

Drying: Dry the coated screen horizontally with the print side down in a clean light safe area. The following will help to ensure complete drying:

•  86° to 104° degrees

•  30% to 50% relative humidity

•  Good air circulation

The use of a screen drying cabinet with heated airflow can help in maintaining these conditions.

Exposure

Clean the film positives and vacuum frame glass prior to exposure to minimize pinholes.

Exposure is affected by mesh color, emulsion type, coating thickness, lamp type and the age of the bulb itself.

For best results use an exposure calculator to determine the correct exposure time.

Note: The use of film positives that are either frosted or have weak black density can reduce resolution and definition qualities of the coated screen.

Washout Image Area: 

Gently spray both sides of the screen with cold to lukewarm water, wait a few seconds to allow emulsion to soften then wash print side of screen until image is fully open.

Rinse both sides thoroughly and dry.

The use of a drying cabinet or fans is recommended to dry the screen. 

Use a pressure washer on fan spray for developing the screen.

Reclaim:

Use ECO2770 Ink Degrader or ECO5000 TKO One Step Ink Degrader & Emulsion Remover to remove all excess ink from the frame.

Remove the emulsion with SCP625 Ready to Use emulsion remover or SCP650 Concentrated emulsion remover in dip tank.

UseSCP708 to remove haze and ghost if required.

Degrease with SCP623, rinse both sides thoroughly and let dry.

Storage:

Store the emulsion in a cool dry area. Pre-sensitized emulsion has a minimal shelf life of at least one year when stored at room temperature.
Use Kolormatrix PVA-SBQ emulsion within one year for best results.
Coated screens may be stored for up to one month when kept under the following conditions.
•  59° to 77° degrees F 
•  30% to 50% relative humidity
