INSTRUCTIONS FOR HANDLING & USE
Murakami Aquasol HV is best handled under yellow safelights. Avoid exposing it to sunlight, fluorescent and incandescent lights.
Murakami Aquasol HVP is ready to use immediately after opening. It is not required to add any sensitizer.
Prior to using Murakami Aquasol HV, it is crucial that you remove any contamination, residual inks, cleaning chemistry, or any dirt and dust. Ghost Remover (a non-caustic water soluble liquid) is capable of removing residual ink and/or emulsion. Degreaser can also get rid of any other contaminants. Do not forget to completely dry the screen before coating.
To apply Murakami Aquasol HV use a clean dry coating trough that has a smooth surface for flawless coating. Apply one or two coats of Murakami Aquasol HV to the printing side of your screen. Rotate the frame 180 degrees and apply one or two coats to the squeegee side. You can add more coats if you are using thicker stencils.
During the drying phase you will rotate the screen horizontally with the print side facing down in a contaminant free, and light safe environment. The following steps, in addition with a screen drying cabinet, will guarantee a complete drying process:
To minimize pinholes, clean the film positives and vacuum frame glass prior to exposure. Exposure is affected by color, emulsion type, coating thickness, lamp type, and the age of the bulb. For the best results, use an exposure calculator as well as these recommended time frames: Below is a list of suggested exposure times using a 5KW Metal Halide lamp at a distance of 40°.
Mesh Count 86-White: 50-60 seconds
Mesh Count 110-White: 45-55 seconds
Mesh Count 200-Yellow: 45-50 seconds
Mesh Count 300-Yellow: 35-40 seconds
Mesh Count 350-Yellow: 25-30 seconds
Gently spray both sides of the screen with lukewarm water, wait a few seconds to allow emulsions to soften then wash the print side of the screen until the image is fully visible. Rinse both sides thoroughly then set to dry. Drying cabinets, or fans are recommended for drying the screen.
Use Screen Cleaner to remove any excess ink on the frame and rinse thoroughly. Use a Degreaser and rinse both sides thoroughly, then set to dry.
