LIQUID FILM Photopolymer Screen Emulsion
LIQUID FILM Photopolymer Screen Emulsion is a very unique and heavy one part fast drying and exposing photo-polymer emulsion based on "sbq" technology. liquid film is recommended when a heavy stencil up to 400 microns is required, specially when you are using 30/40/60/86 mesh counts to apply glitter inks- that requires multiple coatings. Liquid film also works very well when heavier stencil is needed with out putting multiple coatings- with 2/2 coats you may be able to achieve 50 to 70 micron, 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 just want just heavier One Part, SBQ emulsion, you can add 3 to 5 % water to the emulsion to thin Liquid Film down.
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, very sharp edges and 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 it's 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

Before applying the Liquid Film on the screen, make sure that screen is cleaned with degreaser and dried thoroughly. let the emulsion dry and then wash with a soft mist of water to create the image
Distance for the exposure should be about one and a halftimes the diagonal measurement of the art work from point light sources. yellow and orange mesh require at least 50% more time than white mesh.
the times given below are based on white mesh at approximately. we recommend to use step wedge testing so that depending on amount of film being deposited, the printer should be able to get the feel of the product. liquid film acts as a fast "sbq" photo polymer, but the high solids and application make all the difference in exposure time.
