SCREENCOAT WHD EMULSION

EMULSION SCREENCOAT WHD

Versatile and highly durable liquid photo emulsion for screen printing with water-based, plastisol, UV, and solvent-based inks.

A universal emulsion that ensures good durability against both chemical and mechanical stress.

It is a two-component emulsion with a hardener, which increases the durability of the emulsion for larger print runs.

Screencoat WHD emulsion does not contain any chemicals that would require registration with the Chemicals Office.

PREPARATION INSTRUCTIONS:

1. Shake the hardener (diazo) into a tightly sealable container.

2. Add 50 grams of distilled water and mix well – stir for a few minutes.

3. Let it stand for 15 minutes to release air bubbles.

4. Mix into the emulsion and let it stand for one to two hours, preferably longer.

5. Then apply the prepared emulsion to the screen.

6. The Screencoat WHD emulsion can be used repeatedly without problems, it is only important to store it properly after use (dark place and well-sealed container). We recommend stirring it well before reuse.

APPLICATION OF SCREENCOAT WHD EMULSION:

1. Apply the emulsion in a dark room – darkroom.

2. The screen must be pre-cleaned, degreased, and dry (see cleanerStripcoat 110  and Deterstrip 110).

3. Two even strokes along the side of the screen that will be in contact with the print.

4. Two even strokes along the side of the screen where the ink will be applied.

5. Dry the sensitized screen with warm air up to 40°C, 20-30 minutes in a horizontal position for printing.
The table provides only approximate values for exposing the white mesh with a 5 kW halogen lamp. We recommend adjusting the exposure time based on the mesh color, thread density, light source intensity, and the distance between the light source and the screen.

Advice:  For yellow mesh, extend the time by 25 – 30% compared to the times in the table.

SHELF LIFE: Screencoat WHD emulsion, when mixed with hardener and stored properly in a cool place (5-10 degrees), is usable for a longer period.
