Storage
Unsensitised Dirasol should be stored in as cool a temperature
as possible, but not below 5°C or above 35°C. Sensitised
Dirasol should be stored under similar conditions, in its original
container with the lid sealed. The product will remain stable at
22°C for 3 months, but this can be extended by keeping in a
household type refrigerator. The storage time will be significantly
reduced as the temperature increases above 22°C.

Safety and Handling
Dirasol Emulsions:
• Are formulated to be free from any chemicals toxic to health,
carcinogenic, mutagenic or reprotoxic according to Directive
67/548/EC

• has a flashpoint greater than 55°C and is therefore not
classified as a “dangerous substance” under the Dangerous
Substances and Explosive Atmospheres Regulations (DSEAR).

The exposure values quoted are the times required to fully cure
and therefore completely harden the sensitised emulsion on a
120.40 dyed (62.64 white for Dirasols 25 and T) monofilament
screen, with a 2+2 coating (see also Dirasol T technique).
Using these through-cure exposure values prevents emulsion
being washed away during development and ensures stencils
of optimum resolution, definition, durability and decoatability.
Stainless steel, dyed fabrics and multi-coat stencils require
longer exposure.

Developing
Place the screen in a sink or automatic developing machine
and gently spray both sides with cold or warm water (not above
40°C). After 1-2 minutes the spray pressure can be increased
slightly. Continue developing until all parts of the image appear
clean and sharp. Immediately after developing, remove surface
moisture with a screen vacuum or by gently mopping both sides
of the screen (which should be in a horizontal position) with a
soft moist chamois leather. This will speed final drying and also
remove any impurities that might cling to the open areas of the
screen.

Final Drying and Spotting Out
Dry the stencil with the aid of a warm air fan. Any small
blemishes or pinholes, usually caused by dust specks or spots
on the positive, can be filled in by spotting out with a brush
containing screen filler or sensitised Dirasol emulsion. After
spotting out, the screen is ready for printing.

Reclaiming the Screen
In automatic screen cleaning machines, remove ink residues
using an Xtend Screen Cleaner and decoat stencil using diluted
Xtend Strip Liquid Concentrate. When removing by hand, remove
all traces of ink with a rag soaked in Xtend Screen Cleaner.
Rinse the screen with water and then apply diluted Xtend Strip
to both sides of the stencil. Leave for a few minutes. The stencil
can then be easily removed with a strong water jet or high
pressure water gun.
