Polyzol Direct Emulsion DE422 is a dual cure photopolymer emulsion formulated for high quality graphic printing. This emulsion is a one-pot system and can therefore be used straight from the pot. Polyzol DE422combines excellent resolution and definition with wide processing latitude. 1. Position the positive, emulsion side in contact with the Polyzol coating on the print side of the dry screen, securing it with small pieces of clear tape. 2. Place the complete screen into vacuum frame and ensure perfect contact before exposure.

Diazol Universal PU220 is a Diazo sensitised dual cure emulsion combining excellent print quality and durability with wide processing latitude. PU220 has a blue color for easy spotting out on colored or white mesh. It has a tack free surface with good tape resistance and is easily de-coatable.   Spotting Place the screen in front of a white or yellow light source and check for pinholes or blemishes. These are usually caused by dust specks or spots on the positive film or vacuum frame glass. Spot out with suitable filler.

Diazol U99HB is a Diazo sensitized, two-pack photopolymer emulsion. This light blue, dual cure emulsion is designed for the production of PCB solder masks or for applications where very high builds are required. Set the screen on edge slightly inclined away from the operator and then follow this procedure:

1. Apply one or two coats of Diazol U99HB, wet on wet, to the print side of the screen.
2. Apply one or two coats of this emulsion, wet on wet, to the squeegee side of the screen.

Diazol TX600 is a diazo sensitized, two-pack emulsion formulated for Direct Photostencil making. This dark blue emulsion resistant to all types of water based and plastisol inks. The print run resistance can be considerably increased by chemical hardening with HDT-001. Diazol TX600 is recommended for textile printing.

Diazol S42 is a diazo sensitized two-pack, blue emulsion, formulated for graphic and specialty printing. It is the fastest exposing diazo emulsion of the range and combines good resolution with outstanding durability.

UGI is a two-pack screen ink with outstanding resistance to many chemicals and solvents and excellent adhesion to a wide range of difficult to adhere to substrates, such as metal (including aluminum, copper, brass, tin coated metal and iron), glass, ceramic, plastic, mirror, Bakelite, Formica, Acrylic, Polyethylene (PE), pretreated Polypropylene (PP), Nylon and some Polyester. UGI gives good adhesion to substrates coated with resin, silicone and wax. To improve adhesion, the substrate should be cleaned with Thinner 2900 before printing. UGI is not suitable for printing outdoor displays which require long term weather stability.

POXY Series of screen ink is a 2-pot system, exhibits high gloss, chemical resistance and good adhesion when the print undergoes a mild stoving schedule. Catalyzed ink is highly recommended for finishing where excellent is demanded, with outstanding resistance to many chemicals and solvents and excellent adhesion to a wide range of difficult to adhere to substrates, such as metal (including aluminum, copper, brass, tin coated metal and iron), glass, ceramic, plastic, mirror, Bakelite, Formica, Acrylic, Polyethylene (PE), pretreated Polypropylene (PP), Nylon and some Polyester. PX is suitable for printing outdoor displays which require long term weather stability.

PPG is a solvent-based screen printing ink suitable for printing onto containers made from untreated or pretreated polypropylene. This ink system has a high gloss finish and excellent adhesion, giving it good rub-resistance. PPG can be printed through any type of mesh, but for the best printing results it is recommended that monofilament P90-48 to P120-34 be used.

• PPG can be printed through a variety of solvent resistant stencils, such as Diazol (PU220), and Diazol Fast (S42).
• 1Kg of ink will print an area of 65-75 m 2 through a P120-34 mesh.

PP is a gloss finish solvent-based, single-pack ink specially designed for printing pretreated polyethylene and polypropylene. When thinned, PP can be used with high-speed automatic or semi-automatic printing machines. PP is very fast drying and has excellent adhesion resulting in durable ink films with good resistance against a wide range of products including bleaches, motor oils and most detergents. However, PP is not resistant to cosmetics or products containing alcohol, such as certain lotions or perfumes. PP is also suitable for printing various types of aluminum. Please see “ the detail information in Metal printing.”

Can be printed through a variety of solvent resistant stencils, such as Diazol (S42), Polyzol direct DE422 and Diazol Universal PU20. A snap distance of about 2-3 mm is required for a good release of the print from the screen. Apply Spray Way SW82 all over the print table to firmly hold the substrate in place during printing. Due to the wide range of coatings available, it is advisable that the ink be tested fully prior to printing.
