Polyzol HB5 is a one pot 3D emulsion system, easy to coat and to be applied instantly. 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 Polyzol HB5, 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.
3. If a higher build of Polyzol HB5 is required extra coats should be applied, wet on wet, to the squeegee side.
4. Ensure that a suitable coating trough is used to deposit an accurate and consistent coating of emulsion.

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.

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.
