APPLICATIONS

Murakami Aquasol HVP is a pure photopolymer emulsion specially designed for use with Plastisol Discharge and Water-based textile ink systems. The Pure Photopolymer Emulsion formula is curated for faster exposure compared to diazo-based emulsions. Murakami Aquasol HVP can be used as-is for sharp plastisol prints, or with additives such as diazo or Murakami hardeners for improved water resistance. It is important to note that stencils treated with Hardener A&B will be harder to reclaim.


PHYSICAL PROPERTIES

  • Pink colored PVA-SBQ Pure Photopolymer Direct Emulsion

  • Pre-sensitized for immediate use

  • Quick exposures, 3-5x faster than most diazo-based emulsions

  • As-is use with Plastisol; addition of 8 grams of diazo per gallon for Discharge and Water-based ink systems; addition of MS or A&B Murakami Hardeners

  • Almost no signs of pin holes or fish-eye

  • Durable and long-lasting on press

  • Boasts outstanding resolution and definition properties

  • 42% solids content


INSTRUCTIONS FOR HANDLING & USE

Murakami Aquasol HVP should only be handled under yellow safelights, and not exposed to sunlight, fluorescent and incandescent lights.


Sensitizing:

Murakami Aquasol HVP is ready for immediate use without the addition of a sensitizer.


Mesh Preparation:

Before applying Murakami Aquasol HVP to your screens, make sure your mesh is free from any contamination, residual ink or regular dirt and dust. To assist you in mesh prep, Garston offers numerous degreasers and haze or ghost removers to help prepare your screens. These include:
Autotype CPS Degreaser Concentrate

  • Ulano UlanoGel No. 23 Fabric Abrader and Degreaser

  • Chemical Consultants Enviroclean Natural Citrus-Based Degreaser


Coating Procedure:

When ready for application, use a clean and dry coating trough or scoop coater. It is essential this trough or scoop coater has a nick-free surface for smooth coating. Begin coating on the print side, then rotate the frame 180 degrees and coat the squeegee side. Most projects only require one to two coats of Murakami Aquasol HVP on both sides. For thicker stencils, use additional coats of your Murakami Aquasol HVP to the print side.


Drying:

In order to properly dry the coated screen, it must be kept horizontally with the print side down. A clean, light-safe area is essential for proper drying. You may use a screen-drying cabinet with heated airflow to maintain ideal conditions, which include:

  • 86º to 104º degrees F (30º to 40º C)

  • 30% to 50% relative humidity

  • Good air circulation


Exposure:

Prior to exposure, you should clean the film positives and vacuum frame glass in order to minimize pinholes. Exposure is affected by mesh color, emulsion type, coating thickness, lamp type, and the age of the bulb. It is recommended to use an exposure calculator to determine the correct exposure time, as well as a lamp specifically for emulsions. Below is a list of suggested exposure times using a 5KW Metal Halide lamp at a distance of 40°:

  • Mesh/Inch = 86, White: 55-65 seconds

  • Mesh/Inch = 110, White: 50-60 seconds

  • Mesh/Inch = 200, Yellow: 70-90 seconds

  • Mesh/Inch = 300, Yellow: 60-80 seconds

  • Mesh/Inch = 350, Yellow: 35-50 seconds


*Add 25% to exposure time if diazo has been added for water-base and discharge inks


Washout:

For the washout, gently spray both sides of the screen with cold-lukewarm temperature water, waiting a few seconds to allow the emulsion to soften. Then, wash the print side of the screen until the image is fully open. When the image is ready, rinse both sides thoroughly and dry. We recommend the use of fans or a drying cabinet in order to dry the screen. For developing the screen, use a pressure washer on fan spray.


Reclaiming:

Use lukewarm water on both sides of your screen before transitioning to a screen cleaner. The screen cleaner will remove excess ink as well as remnants of hazing or ghosting if needed. While you are in the washout process, let the emulsion soak into your screen and soften. After, wash both sides of the screen again with lukewarm water until the image has disappeared.


INSTRUCTIONS FOR STORAGE:

Murakami Aquasol HVP  should be kept in a cool, dry area. This pre-sensitized emulsion has a minimum one year shelf life when stored at room temperature. For best results, use Murakami Aquasol HVP within one year. If you choose to leave your screens coated, they can be stored up to one month if kept under these specific conditions:

  • 59º to 77º degrees F (15º to 25º C)

  • 30% to 50% relative humidity


Extending the Life Of Your Emulsion:

  • Everytime you use your Murakami Aquasol HVP, you must remember to gently mix it.

  • Heat will break down the components of your Murakami Aquasol HVP. Keep it in a cool area to make it last longer. Temperature and humidity can speed up the expiration date of your Murakami Aquasol HVP if not properly noted.

  • Avoid air or light leaks by keeping the lid to your Murakami Aquasol HVP tightly closed.

  • Keep track of every use by adding a last used date to your container.
