QXL Photopolymer Emulsion for Plastisol and Solvent ink (Hybrid SBQ Emulsion).
QXL Photopolymer Emulsion HYBRID for Plastisol and Solvent ink is based on SBQ and photo monomers technology. QXL Photopolymer Emulsion is fast drying and exposing- QXL carries some of the fastest monomers with very effective photo-initiators to make the product faster, especially for LED lights. QXL is high in solids and viscosity- You do not have to apply too many coatings to get the optimum emulsion film thickness.
This Photopolymer emulsion is recommended for Plastisol, Solvent, and water-based ink systems.
QXL may also work for water-based inks by adding a small amount of
Diazo. QXL offers durability and excellent image, yielding a smooth, even coating, sharp edges, and high resolution. Since this emulsion is based on SBQ technology, it does not require Diazo for Plastisol and Solvent inks and should be handled only in a yellow-safe light environment. Because of their high solids content, coated screens dry in less time and require fewer coats. In most cases, one coat on each side of the screen is all that is needed.
Guideline for QXL Photopolymer Emulsion:
QXL(Blue) is a well-proven SBQ one-part photopolymer used by some of the largest printers in the country. QXL is a suitable replacement for QTX, ORANGE, QLT, CHROMA-LIME, CHROME-BLUE, PL2, PV, HVP, LBX, and HXT.
Before applying the emulsion to the screen, make sure that the screen is cleaned with a Degreaser and dried thoroughly. Let the emulsion dry and then wash with a soft mist of water to create the image.
Highlights For QXL:
- QXL may replace any one-part (SBQ) emulsion in the screen printing industry.
-
Works for Plastisol, water-based (Diazo should be added) ink systems, and solvent ink systems
-
heavy so that you may not require too many coats - If a thinner viscosity is required, add four oz. of water to a gallon of QXL.
-
Dries faster due to higher solids
-
Very fast exposure
-
long shelf life
-
easy to re-claimer
-
very high resolution
-
zero pinholes if applied properly
-
excellent edge definition and bridging
-
Works well with LED light- 4-7 seconds exposure time

Exposure Times:
QXL is a very fast-exposing emulsion. In some LED units, it may require 4-5 seconds to expose 1/1 application. The best suggestion is to use the wedge step procedure before exposure to determine the optimum exposure time. For LED units, start with 4 to 7 seconds and go up to 10 seconds. The 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 below are based on the white mesh at approximately 40 inches.

If the image does not open, that means you overexposed the emulsion.
* Though QXL Photopolymer emulsion yields a pinhole-free screen, in case of any pinholes, use block-out to close the pinholes.
*To reclaim, use: XER 5, XER10, or XER25 (diluted 4 to 1, 9:1, and 24 to one). Reclaimer to remove the unwanted stencil.
This is what QXL offers:
- The latest technology has given screen printers the tools to quickly expose hybrid dual-cure SBQ emulsions that should have good latitude and may be used for all ink systems.
- The emulsion should dry faster and should resist humidity.
- It should bring high clarity and sharpness to the image, meaning good resolution and high edge definition.
- It should have high solids to give high E.O.M. (for two-to-one coating on 110 counts, 23 microns) and not clog filters on the I-unit from M&R or the sewer system.
- Reclaim as quickly as possible, even when the Screen Printer uses stronger Press Wash and Ink degradant. A good Emulsion can withstand solvents.
- After easy reclaiming, there should be no haze left from the emulsion.
- The emulsion may be used for Plastisol, Solvent, UV, and water-based inks.
- The Emulsion should have excellent coating properties, good flow, and leveling so that it goes onto the screen evenly and smoothly.
- The Emulsion should not give way to pinholes on a clean screen.
- The emulsion should furnish a strong stencil that should produce the longest run possible.
- It should be able to produce half-tones
- One emulsion for all ink systems—QXL is recommended for UV, solvent, and Plastisol ink; adding Diazo works perfectly for water-based ink.
