Screen Printing Emulsion - Murakami

More information about the Murakami screen printing 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 the next personalisation with screen printing ink
• Easy to reclaim with screen printing emulsion remover. You will find it in Related Products (Ref. 012373)

AQUASOL No. 2 (Ref. 045284)

• Presensitised single-component photopolymer emulsion with excellent water resistance
• Suitable for textile applications with water-based inks
• Ready-to-use, it can be applied directly onto the screen
• Includes 3 g container with diazo salts to increase durability if desired. Its use is optional
• In the case of using diazo: (1) use 10% of the emulsion volume, (2) dissolve it in water, (3) mix it with the emulsion and (4) let it stabilise
• 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
• 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 solvent-based, UV and water-based inks
• Before using the emulsion, it must be mixed with diazo powder. Included is 1 tub of 3 g, for 1 kg of emulsion
• Preparation of the mixture: (1) dilute 3 g diazo in 100 ml water; (2) add to the emulsion and stir until integrated; and (3) allow to stabilise
• Excellent resistance to solvents
• 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 it to the mesh
• Before use, stir the emulsion and leave it 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
