 Product Description

Murakami - Aqua Sol HV Emulsion PINK

  • Murakami Aquasol HVP like Aquasol HV is a high viscosity emulsion to create extremely durable stencils for all ink systems. 
  • It has a more transparent quality that can help when registering by hand on press. 
  • Exposes fast and provides one of the most durable stencils possible for difficult inks like water base and discharge when combined with diazo additive and hardened with Murakami Hardeners.

PHYSICAL PROPERTIES

Pink colored PVA-SBQ Pure Photopolymer Direct Emulsion
• Pre-sensitized for immediate use
• Fast exposures, 3-5x faster than diazo based emulsions
• Excellent for use with Plastisol as is, or for Discharge and Water-based ink systems when 8 grams of diazo per gallon is added and when hardened with Murakami Hardeners. (MS or A&B   Hardeners)
• Virtually pin hole and fish eye free
• Extremely durable on press
• Outstanding resolution and definition properties
• 42% solids content.

HANDLING

Handle under yellow safelights. Avoid exposure to sunlight, fluorescent and incandescent lights.

SENSITIZING

This PVA-SBQ emulsion is ready to use. There is no need to add sensitizer. See special applications on the back of this page for water base and discharge inks.

MESH PREPARATIONS

 

It is important to remove any contamination, residual inks, cleaning chemistry, or general  irt and dust. Murakami 701 Haze/Ghost Remover (a non-caustic water soluble liquid)
will remove residual ink and/or emulsion. Murakami 801 Screen Degreaser will help eliminate any further contaminants. 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 frame 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.

Mesh/Inch          Color          Seconds

      86                     W                55-65

     110                    W                50-60

     300                    Y                 60-80

     350                    Y                 35-50

Note:  All exposure times listed above are suggested times using a 5KW Metal Halide lamp at a distance of 40”. Add 25% to exposure time when diazo is added for water base and discharge inks.

WASHOUT

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.

RECLAIMING

  • Use Murakami 501, 505 or 507 Screen Cleaner to remove all excess ink from the frame.
  • Remove the emulsion with Murakami 601, 605, or a solution of Strip Super-P. Rinse thoroughly.
  • Use Murakami 701 to remove haze and ghost if required.
  • Degrease with Murakami 801, rinse both sides thoroughly and let dry.

STORAGE AND HANDLING

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 Murakami 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 (15° to 25° C)
• 30% to 50% relative humidity

SPECIAL APPLICATIONS

Suitable for use with water based and discharge inks when diazo is added and screen is hardened with Murakami MS Hardener and/or Hardener A&B. Stencils treated with Hardener
A&B will be harder to reclaim. Add only one third of a bottle of water to diazo bottle and shake well before adding to emulsion.
