Fotecoat 1838 Red Emulsion is an easy to use emulsion that requires no sensitiser. Slower to exposure (6-10mins) than Fotecoat 1833 but is less senstive to accidental UV exposure i.e sunlight, fluorescent lights. Ideal for use with waterbased inks and paints.
Fotecoat 1838 Red Emulsion is magenta, the stencils allow excellent see-through
- Solids content 38%
Fotecoat 1838 Red Emulsion Application Advantages
- Can be coated on all types of meshes; on white mesh the resolution/definition is satisfactory
- High resolution coupled with excellent stencil edge sharpness
- Can be decoated with the usual products
- To speed-up the wash out for thick stencils after exposure an immersion for 5-15 min. in a water bath is possible
MANUAL AND MACHINE COATING
- Manually the ready to use emulsion can be coated 1/1 or 1/2 wet in wet. On coarse meshes 1/1 coating is possible
- The viscosity is ideal for machine coating. If necessary the emulsion can be diluted with water without losing light sensitivity
- To produce a flatter stencil profile with a lower Rz-value (to improve print edge quality) additional coats can be added after an intermediate drying cycle. After each such cycle the stencil thickness increases by 1-2 μm and the Rz-value becomes lower
- After coating pour the emulsion from the coating trough into an empty can so that it can degas; this way air bubbles can be avoided in the stencil which results in less pin-holing
- Such cycle the stencil thickness increases by 1 - 2 microns and the Rz-value becomes lower
- After coating pour the emulsion from the coating trough into an empty can so that it can degas; this way air bubbles can be avoided in the stencil which results in less pin-holing
STENCIL QUALITY
- Excellent mesh bridging. This causes an excellent stencil edge together with medium resolution at short exposure times. A perfect stencil can be achieved on dyed mesh if the correct coating and drying technique is applied. In combination with white mesh the resolution suffers slightly
- The cleaning of plastisols should be done with white spirit and not with stronger solvents
