Fujifilm Dirasol 125 Leaflet

Product Information

One pot system, ultra-fast exposure speed, easy decoatability,

outstanding resistance to plastisol and water-based textile inks.

Outstanding resolution and definition. Highly resistant to solvent 

based and conventional UV inks. Good resistance to high humidity 

conditions.

Dirasol photopolymer emulsions are pre-sensitised, and therefore

sensitive to light at all times. All handling of Dirasol emulsions should

be carried out in light which is low in blue and ultra-violet content. A

photographic safelight is not essential but yellow or weak tungsten

illumination is. A useful form of light for the workroom is provided by

gold fluorescent tubes. Daylight should be excluded or filtered by a

yellow lacquer coating or film applied over windows. Coated screens

should be stored in total darkness.

Degrease the mesh in automatic screen cleaning machines using 

Xtend Prep 300 Sprayable Degreasing Concentrate or by hand with 

Prep 102 Degreasing and Emulsifying Concentrate. When degreasing 

by hand using Prep 102, wet the screen and apply with a sponge or 

brush and then rub the mesh with a light circular motion. Ensure that 

both sides of the screen are thoroughly treated. Leave to stand for a 

few minutes and rinse with cold water to remove all traces of Prep. 

Allow the mesh to dry before coating.

Fujifilm Coating Troughs are designed for accurate and consistent coating 

of direct photostencil emulsions. The troughs are composed of precision 

extruded aluminium channelling fitted with injection moulded end pieces. 

The channelling has a hard anodised finish which effectively seals the 

surface. This makes cleaning easy and also protects from corrosion. The 

end pieces have a special shoulder which ensures the coating edge is 

consistently at the optimum angle in relation to the screen. To help eliminate 

the beads formed at the extremities of conventional troughs, special slots 

have been incorporated into the end pieces. These features permit even 

relatively inexperienced operators to coat screens faster and more accurately. 

Fujifilm Coating Troughs have been designed to deposit medium coating 

thicknesses. It is therefore possible to coat a screen to a given stencil 

thickness with fewer strokes than would be required with a sharper or less 

precise edge. The amount of emulsion used to coat a given area of a screen 

is principally governed by the fineness of the mesh. Fujifilm Coating Troughs 

have sufficient capacity to cover approximately 1.5-2m in a single stroke 

and are available in sixteen standard sizes. When ordering please specify the 

overall length required, measured from the outside edge of one end piece to 

the other.

Apply a simultaneous single coat to each side of the screen, followed

by a second coat to the squeegee side. If a higher build is required,

extra coats should be applied to the squeegee side of the screen. NB:

For Textile applications (i.e. Dirasol 125), a single coat applied

simultaneously to both sides of the screen should be sufficient.
