HANDLING

Handle under yellow safe lights. Avoid exposure to sunlight, flourescent and incandescent lights.

SENSITIZING

This PVA-SBQ emulsion is ready to use.There is no need to add sensitizer.

MESH PREPARATION

It is important to remove any contamination, residual inks, cleaning chemistry, or general dirt and dust.
Completely dry the screen before coating.

COATING PROCEDURE

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 F (30° to 40° C)
• 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 frameglass 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.
It is important that a lamp designed for exposing screen printing emulsions is utilized.

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.

86 W 55-65 Secs
110 W 50-60 Secs
200 Y 70-90 Secs
300 Y 60-80 Secs
350 Y 35-50 Secs

Note: All exposure times listed above are suggested times using a 5KW Metal Halide lamp at a distance of 40”.

WASHOUT

Gently spray both sides of the screen with 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.
