Photo Emulsion for screen printing - Murakami

More information about Murakami screen printing photo emulsion

• You must apply a thin layer on both sides of the mesh.
• It makes it easy to print designs on the screen.
• It leaves the mesh soft and smooth for subsequent personalisation with screen printing ink.

AQUASOL No. 2 (Ref. 045284)

• Presensitised single-component photopolymer emulsion with excellent water resistance and high durability.
• Suitable for textile applications with water-based inks.
• Ready-to-use, it can be applied directly onto the screen without using an activator.
• Includes a 3 g container with diazo salts to extend its durability. Just dissolve diazo with water, the equivalent of 10% of the emulsion volume, mix with the emulsion and leave to stabilise. 
• Fast exposure with good definition and long life. It requires less exposure time than diazo photo emulsions.
• Suitable for manual machines and automatic carousels.

ONEPOT C2 (Ref. 045285)

• Ready-to-use presensitised single-component photopolymer emulsion. No diazo required.
• Suitable for solvent-based inks, plastisol inks and UV inks.
• Highly sensitive, even to white light, and faster exposure.
• Excellent solvent resistance.
• Good resolution and fine detail reproduction.
• High-density emulsion.
• Very long shelf life. The emulsion holds after several months in storage.
• Suitable for use with manual machines and automatic carousels.

SP-9500 (Ref. 045286)

• Bisensitised monomer dual diazo emulsion with 2 components: emulsion and diazo sensitiser.
• Suitable for all inks: solvent-based, UV and water-based.
• Requires diazo powder before application. A 3 g container is included in the box. Dissolve diazo with water, the equivalent of 10% of the emulsion volume, and mix with the emulsion.
• Excellent solvent resistance and great durability.
• Outstanding resolution and good reproduction of fine details.
• Easy to reclaim with screen printing emulsion remover. You will find it in Related Products (Ref. 012373).
• Lasts up to 2 weeks after mixing with diazo.
• Low thickness.

THINGS TO KEEP IN MIND

• We recommend filtering the mixed emulsion with screen mesh before putting it on the squeegee to coat the screen. This will help you prevent pinholes and fisheyes.
• We recommend cleaning the screen and the working area so that the coating is thin and uniform. Any dust particles could leave pinholes in the design.
• The emulsion layer must be the right thickness. If it’s too thick, it will come out blurred. If it’s too thin, the print will be jagged.
• Apply in a dark and closed place. You can use a red or yellow light bulb to see the process.
• Store in a cool place away from UV light.

INSTRUCTIONS FOR USE

• Wash and remove grease and any foreign contaminants with a degreaser.
• When using SP-9500 emulsion, mix with diazo before applying to the mesh.
• Before use, stir the emulsion and leave to stabilise for a day. Filter the emulsion with a 250T mesh to prevent fisheyes or air bubbles if you plan on using it immediately. When using Aquasol, leave to stabilise for 1 hour or until the bubbles disappear.
• Slowly coat the screen with a squeegee to avoid air bubbles. When using SP-9500 and One Pot C2, dry the emulsion at 40ºC before placing the pattern.
• Dry the screen in a warm room, but don’t use high temperatures to preserve the emulsion’s quality and stability.
