INSTRUCTIONS FOR HANDLING & USE
Murakami Aquasol Photocure TXR SBQ should only be handled under yellow safelights and should avoid exposure to sunlight, incandescent and fluorescent lights.
Murakami Aquasol Photocure TXR SBQ Photopolymer is a PVA-SBQ emulsion that comes for immediate use and does not require any sensitizer.
All contamination should be removed before using Murakami Aquasol Photocure TXR SBQ. Any residual inks, cleaning chemistry, or dirt and dust will hinder proper emulsion application. Ghost Remover (a non-caustic water soluble liquid) and Degreaser can eliminate any other contaminants. Completely dry the screen of removers and degreasers before coating.
When applying Murakami Aquasol Photocure TXR SBQ use a clean, dry coating trough or scoop coater with a nick free surface for smooth coating. Apply one to two coats of emulsion to the side you are printing on. Rotate the frame 180 degrees and apply one to two coats to the squeegee side. For thicker stencils you can add additional coats if you desire.
While drying, rotate the screen horizontally with the print side facing down in a contaminant free, and light safe space. The following conditions will guarantee complete drying:
• 86° to 104° degrees F (30° to 40° C)
• 30% to 50% relative humidity
• Good air circulation
A screen drying cabinet with heated airflow can also help achieve these conditions.
By cleaning the film positives and vacuuming the frame glass prior to exposure you can greatly minimize pinholes. Exposure is influenced by color, emulsion type, coating thickness, lamp type, and the age of the bulb. Exposure counts listed below are used with reference to a 5KW Metal Halide lamp with 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, within seconds the emulsions will soften, which is when you can wash the print side of the screen until the image is visible. Rinse both sides then set up to dry. Drying cabinets and fans are recommended for drying your screen.
The use of Screen Cleaner can remove excess ink on the frame. Always remember to rinse thoroughly after using application cleaners. Follow up the use of a screen cleaner with Degreaser and rinse both sides thoroughly, then set to dry.
INSTRUCTIONS FOR STORAGE:
Store emulsions in a cool and dry area. Unsensitized emulsions can last nearly up to a year if they are stored at room temperature. Murakami PVA-SBQ emulsions used within a year usually produce the best results.
Coated screens can be stored for up to one month when stored in 59° to 77° degrees F (15° to 25° C) with 30% to 50% relative humidity.
Extending the Life Of Your Emulsion:
Always remember to gently mix Murakami Aquasol Photocure TXR SBQ when in use.
Keep your Murakami Aquasol Photocure TXR SBQ in a cool area. Exposure to heat will break down the components of the emulsion.
Always keep the lid tight to help prevent against air or light leaks. Temperature and humidity are two huge factors in the expiration of Murakami Aquasol Photocure TXR SBQ.
To keep track of how often you use your Murakami Aquasol Photocure TXR SBQ, write the date last used on the container.
