LIQUID FILM Photopolymer Screen EmulsionLIQUID FILM Photopolymer Screen Emulsion is a very unique and heavy One. A heavy stencil of up to 400 microns is required, especially when using 30/40/60/86 mesh counts to apply glitter inks- that require multiple coatings. The liquid film also works very well when the heavier stencil is needed without putting multiple coatings- with 2/2 coats; you may be able to achieve 50 to 70 microns; use the round side of the squeegee; you may also apply 2/2 coats and let it dry and then put two more coatings to get heavier stencil. If you want heavier One Part, SBQ emulsion, add 3 to 5 % water to the emulsion to thin the Liquid Film down.
The liquid film is a One-Part SBQ emulsion that is pre-sensitized, ready to use as textile emulsion, and is recommended for plastisol inks and solvents inks- It offers durability and excellent image and produces a smooth, even coating and very sharp edges. It is high resolution. Since this emulsion is based on SBQ technology, it does not require diazo and should be handled only in a yellow-safe light environment. Because of its high solids content, coated screens dry in less time and require fewer coats. In most cases, one coat on each side of the screen should be all you need
Highlights:
- very heavy (60-70,000 cps) emulsion for replacing capillary film
- longest possible run
- developed for plastisol, UV, and solvent ink systems
- fast exposure
- long shelf life
- easy to re-claimer
- very high resolution
- Zero pinholes if apply properly
- excellent edge definition and bridging
Specification & Data:
- color: blue
- solids48%
- viscosity: 80.000/90,000 cps @72F-brookfield viscometer
Guideline:
Before applying the Liquid Film to the screen, make sure that the screen is cleaned with a degreaser and dried thoroughly. Let the emulsion dry, then wash with a soft water mist to create the image.
Exposure:
Distance for the exposure should be about one and a half times the diagonal measurement of the artwork from point light sources. Yellow and orange mesh require at least 50% more time than white mesh.
The times given below are based on the white mesh at approximately. We recommend using step wedge testing so that, depending on the amount of film being deposited, the printer can get the feel of the product. The liquid film acts as a fast "SBQ" photopolymer, but the high solids and application make all the difference in exposure time.
