Fotecoat 1010 Emulsion Features
- Fast, dual cure diazo photopolymer screen process emulsion with separate diazo sensitiser powder in sachets, for solvent based and co-solvent ink systems (inks containing a combination of solvents and water) including water based graphic arts inks and aqueous UV inks.
- Light purple color.
- Medium viscosity.
- Short exposure time.
- Ecologically sound.
- Must be processed and stored at temperatures not over 20°C.
Fotecoat 1010 Emulsion Advantages
- 40% solids content before sensitizing (approx. 36% after sensitizing).
- Can be coated wet on wet without intermediate drying cycle to reach a flat stencil profile with an Rz-value of approximatively 7 - 8 at 10 - 12 microns.
- Low odour.
- Stencils made with FOTECOAT 1010 can be printed with all ink systems containing both solvent/water or only solvents.
COATING TECHNIQUE AND STENCIL BUILD-UP (coating trough .75 mm R)
| Mesh | Coating | Stencil thickness below mesh |
|---|---|---|
| 77-55 polyester monofilament | 2/3 | 16 microns |
| 90-48 polyester monofilament | 2/3 | 12 microns |
| 120-34 polyester monofilament | 2/2 | 9 microns |
| 150-31 polyester monofilament | 1/2 | 6 microns |
To reach a flatter stencil surface and to lower the Rz-value to improve edge sharpness of the print, 1 or 2 additional coats can be applied after the intermediary drying cycle. Stencil thickness will increase by 1 - 2 microns and the Rz-value decrease to 6-7 microns.
Fotecoat 1010 Emulsion is ideal for machine coating. If necessary the emulsion can be diluted with water.
STENCIL QUALITY
Definition and resolution are excellent. Perfect mesh bridging is possible. After wash-out the stencil is very hard and has low swell characteristics. Printing with most ink types is possible.
For long runs with aqueous textile inks and pure water media, Fotecoat 1915 WR Emulsion is recommended.
STORING
- Unsensitized: up to 1 year **
- Sensitized and stored at 20°C (pot life): 2 weeks **
- Shelf life for storing of pre-coated screens in the dark at 20°C: 2 months **
**Age, transportation and storing conditions influence the quality of the emulsion drastically. The freshness of the diazo controls the pot life.
EXPOSURE TIMES
5KW metal halide lamp at 100cm distance; photopolymer bulb at 100 hours operating time.
| Stencil thickness below mesh | Type of mesh | Time in seconds |
|---|---|---|
| 6 microns | 150-31 yellow | 45 |
| 9 microns | 120-34 yellow | 55 |
| 12 microns | 90-48 white | 40 |
| 16 microns | 77-55 white | 70 |
For fine details a post exposure is recommended.
REMOVAL
Click here for all Emulsion Removers. A high pressure gun is recommended.
The longer the exposure, the better the through-curing of the stencil. If necessary make a post exposure. Both render the decoating easier.
