Inmarcol Emulsion

Diazo-sensitized direct screen-imaging emulsion


Series: ACEM


General Information

Inmarcol emulsions are diazo-sensitized direct liquid emulsions that are suitable for most screen printing applications.

Inmarcol-W: Inmarcol-W (ACEM-INMW) is a white, water-resistant emulsion designed for use with water-based and most plastisol inks. This emulsion is designed mainly for textile screen-printing.

Inmarcol-Fast: Inmarcol-Fast (ACEM-INMF) is a blue-green solvent-resistant emulsion with a fast exposing time designed for exposing with low-wattage bulbs. Inmarcol-Fast is recommended for use with all inks except water-based inks. It is not recommended for very long print runs.

Inmarcol-R: Inmarcol-R (ACEM-INMR) is a blue-green emulsion designed for use with all plastisol and solvent-based inks. It is not intended for use with water-based inks. This product provides excellent resolution and definition for fine detail, high-resolution printing. The stencil is very durable for long print runs.

Instructions for Use

Inmarcol emulsions are sold by the gallon. Each gallon comes with the correct amount of powdered diazo sensitizer in a separate mixing bottle.

Under safelight conditions, add cold tap water to the powdered diazo sensitizer in the mixing bottle it comes in, filling the mixing bottle to the shoulder. Replace the cap on the bottle and shake vigorously until the powder is completely dissolved. Add the entire contents of the diazo solution to the Inmarcol emulsion and stir well, preferably with a stir-rer made of stainless steel or plastic. Continue stirring until the emulsion is evenly colored without streaks.

Using an aluminum or plastic scoop coater, coat the screen as follows:
Light Coat - One coat on the printing side and one coat on the squeegee side.
Regular Coat - Two coats on the printing side and two to four coats on the squeegee side.
Heavy Coat - Two coats on the printing side, two to four coats on the squeegee side. Dry the emulsion and then add two or more coats on the printing side.

On the first coating, always coat the squeegee side last.

Dry the screen horizontally in printing position. Dry in warm air not above 100º F (38º C) at 40-50% relative humidity.

For a smoother, more durable stencil, apply one addi-tional coat on the printing side after the first applica-tion of emulsion is thoroughly dried.

Exposure

For best results, use an exposure calculator to determine the correct time for each mesh and emulsion thickness.

Developing

Wash out with water below 100º F (38º C). Wet screen on both sides immediately after exposure. Soak for one to two minutes, then apply a sharp spray until all image areas are open. Blot the screen with absorbent paper or blow excess water off with compressed air.

Shelf Life

Unsensitized emulsion has a shelf life of up to one year from date of manufacture if stored at tempera-tures not exceeding 80º F. (27º C.)

Sensitized emulsion will have a shelf life of 3-6 weeks when stored below 80º F. (27º C.) and up to 3 months when stored household refrigerator. (Allow to reach room temperature before coating.) Do not store sensitized emulsions above 80º F. (27º C.) as this will cause the mixture to harden.

Coated screens may be stored in light safe conditions for up to two weeks prior to exposure.

Removing Stencil (Reclaiming)

Use U-strip Stencil Remover.

Caution: Keep from freezing. Store below 80º F. (27º C.) rev 9/98
