 SAATI SAATItex PHU-MT offers print shops flexibility and functionality in a single, pure photopolymer emulsion package.

Designed to be user friendly and universally suitable for most inks, SAATItex PHU-MT features solid content that produces sharper, higher resolution images when compared to SAATI PV.

The emulsion performs well on hand and automatic coated screens and in laser-to-screen applications. It also remains forgiving across a wide range of exposure times and resists gumming up screens even when underexposed.

Printers can also count on SAATItex PHU-MT at the end of the job. It makes the screen reclaiming process easier than SAATI PV or PHU.

 

 Features and Benefits
      • Dyed blue
      • One-part pure photopolymer emulsion with universal ink resistance.
      • Exposes approximately 8x faster than typical two-part emulsion
      • 45% solids
      • High viscosity easily coats all mesh counts
      • Easy to reclaim
      • Can be used with solvent based, UV and water based inks, without using diazo. 
      • Can be used with Diazo 11 when extra sharpness or high resolution is required*

DIRECTIONS FOR USE
Handle under yellow safelight or low wattage tungsten lights. Avoid exposure to daylight, quartz/halogen lamps, cool white fluorescent lamps or discharge lamps.

Sensitizing & Mixing
Emulsion is presensitized during production and does not require mixing.  

Mesh Preparation & Degreasing

Degrease and abrade new mesh with Saatichem Direct Prep 1 in order to optimize stencil adhesion; dry and store the screen in a dust free, dry environment prior to coating. For more applications, thoroughly degrease mesh prior to use with Saatichem Direct Prep 2.

Coating
Using a high quality scoop coater or coating through, apply one or two coats to the substrate side of the screen, followed by one or two coats on the squeegee side. For a thicker stencil, apply additional coats to the squeegee side prior to drying. For a higher quality stencil with a minimal increase in stencil thickness, apply one or two additional coats to the substrate side of the screen after the initial coats have dried.

Drying & Storage
Thoroughly dry the coated screen at a maximum temperature of 104°F (40°C) in a dust free, dark or yellow light area, with the substrate side facing down to optimize stencil quality. Coated screens should be stored in a dust free, dry, safelight environment.

Exposing
Ensure that all surfaces, emulsion, film and glass are free of dust to minimize pinholes. Contact the emulsion side of the positive with the substrate side of the screen and secure in position before placing the screen in a suitable vacuum frame. Many variables, such as lamp type and age, distance from lamp to screen, mesh type and coating thickness, can affect exposure time. Perform an exposure test with an exposure calculator to determinate correct exposure time for a complete cure.

Developing
Wet both sides of the screen with a strong, finely divided spray of water and continue washing out until all image areas are fully open. Rinse both sides of the screen and dry thoroughly before use. A properly exposed and developed screen will not leave residues on the squeegee side.

Post Exposing
Post expose with daylight or exposure lamp to produce a more water-resistance stencil.

Reclaiming
Remove all ink residues immediately after printing with an appropriate solvent. Remove stencil with Saatichem Remove ER1, ER2, ER4, ER5 or ER10 and a pressure washer. For stains and ghost images, use Saatichem Remove HR3 followed by a pressure washer.

Health & Safety
Before using, refer to appropriate material safety data sheets.

Shelf Life - When sealed in the original container and stored in cool conditions, SAATI products will maintain their original properties for one year from the date of production. 


Emulsion Exposure Differences

Proper screen exposure must take many factors into account – the emulsion type, coating thickness, exposure unit, etc. As a general guideline for the different emulsion types (diazo, dual cure, and photopolymer) use these times as a reference.

Photopolymer – These are typically the fastest exposing emulsions, with many exposing correctly from 30-50 seconds. The shortest times can be seen when using a newer LED-type exposure unit.

Dual Cure – If you have established a good exposure time with photopolymer emulsions, you can typically add 90 seconds (1.5 minutes) to that time for most dual cure emulsions.

Diazo - If you have established a good exposure time with photopolymer emulsions, you can typically add 210 seconds (3.5 minutes) to that time for most diazo emulsions.

These times will depend heavily on your exposure unit and should only be considered as a starting point.
