What Is PVA-SBQ Pure Photopolymer Emulsion?

Screen printing emulsions come in three main chemistry types: diazo (slower exposure, requires mixing a sensitizer powder at first use), photopolymer (faster exposure, pre-sensitized), and dual-cure (combines both). Murakami TXR uses pure PVA-SBQ photopolymer chemistry — the pre-sensitized variety that Murakami pioneered over 30 years ago.

PVA-SBQ stands for polyvinyl alcohol-styrylpyridinium. The styrylpyridinium (SBQ) component is the light-sensitive part that cures under UV exposure, eliminating the need to mix a separate diazo sensitizer. Per Murakami’s TDS, SBQ emulsions expose 3-5× faster than diazo-based emulsions, produce sharper emulsion shoulders for better resolution, and have a longer shelf life since they don’t have the diazo-degradation problem.

Why pre-sensitized PVA-SBQ for textile work?
Pre-sensitized emulsions skip the screen-room setup step (no diazo packet to dissolve, no waiting for the diazo to mix in, no sensitized-shelf-life tracking). For high-volume textile production shops doing daily screen-making cycles, that’s real time saved every batch. The trade-off vs dual-cure emulsions: PVA-SBQ alone is less water-resistant than diazo+photopolymer, so water-based and discharge work requires Murakami hardener for extended-run durability.

What Murakami TXR Is Used For

Murakami TXR is engineered for shops where pre-sensitized convenience, fast exposure, and reliable multi-ink performance matter. If you’re in one of these categories, this is the right choice:

Plastisol Production Shops
Plastisol ready out of the can with the durability for long automated press runs. The pink color is easy to register against under most safelight setups.
Water-Based Textile Printing
TXR handles water-based textile inks when paired with Murakami MS Hardener or Hardener A&B. For shops doing soft-hand water-based prints, the hardener is essential for extended run life.
Discharge Ink Printing
Discharge inks are aggressive on emulsion. TXR handles discharge with Murakami hardener applied for the required durability.
Shops Switching Off Diazo Workflows
Pre-sensitized convenience and the textile-focused chemistry of TXR makes it a natural transition from diazo — same Murakami quality, faster workflow.
Fine Halftone & Detail Work
PVA-SBQ chemistry produces sharper edges than diazo. Holds halftones cleanly without dot gain or detail loss.
Higher Mesh Counts (200-350)
Per Murakami TDS exposure data, TXR works across mesh counts from 86 through 350. Higher mesh counts expose faster and hold finer detail.
Pink Color Preference Shops
If your shop prefers pink emulsion over blue for visibility or simply for personal preference, TXR is the textile-focused PVA-SBQ option in pink. Photocure BLU is the blue equivalent.

Step-by-Step: Coating & Exposing Murakami TXR

Murakami TXR is pre-sensitized and ready to use straight out of the container. No diazo mixing required — coat, expose, develop, print.

1
Degrease the Mesh
Apply mesh degreaser to both sides of the screen and work into a lather with a soft brush. Rinse thoroughly with clean water and allow the screen to dry completely before coating. Murakami 801 Screen Degreaser is the recommended chemistry per the TDS. A properly degreased mesh is the foundation of every successful stencil.
2
Set Up Your Coating Station Under Yellow Safelight
Per Murakami TDS — work under yellow safelights. Avoid exposure to sunlight, fluorescent, and incandescent lights. Set the screen on a stable surface at a slight upward angle.
3
Coat the Print Side
Per Murakami TDS — use a clean dry coating trough that has a nick-free surface for smooth coating. Pour an ample amount of Murakami TXR into the scoop coater. Apply one or two coats of emulsion to the print side. Aim for full uniform coverage with no streaks, gaps, or visible mesh through the emulsion.
4
Flip Screen, Coat the Squeegee Side
Per Murakami TDS — rotate the frame 180 degrees and apply one or two coats of emulsion to the squeegee side. Additional coats may be added to the print side if thicker stencils are required.
5
Dry Flat With Print Side Down
Per Murakami TDS — dry the coated screen horizontally with the print side DOWN in a clean light-safe area. Target 86-104°F (30-40°C) ideal and 30-50% relative humidity with good air circulation. A screen drying cabinet with heated airflow holds these conditions reliably.
6
Position Your Film Positive
Place the film positive on the PRINT SIDE of the screen with the emulsion side of the positive in direct contact with the emulsion. Lock down with vacuum (preferred) or weighted glass — no air gaps, no light leaks. Per Murakami TDS, clean the film positives and vacuum frame glass prior to exposure to minimize pinholes.
7
Expose to UV Light
Expose using a metal halide or LED UV exposure unit. Per Murakami TDS, exposure is affected by mesh color, emulsion type, coating thickness, lamp type, and bulb age — see the Technical Specs tab for the TDS exposure data table as a starting point. Run a 21-step Stouffer wedge test on your first screen to dial in your shop’s optimal time.
8
Wash Out the Stencil
Per Murakami TDS — gently spray both sides of the screen with lukewarm water, wait a few seconds to allow emulsion to soften, then wash the print side of the screen until the image is fully open. Rinse both sides thoroughly. Don’t use high-pressure water — it can damage fine detail.
9
Dry the Developed Screen
Allow the developed screen to dry completely before printing. A fan or warm drying cabinet (under 104°F / 40°C) speeds drying. Once dry, you can spot-touch any small pinholes with blockout — Murakami 901 Blockout Red is ideal for this. The screen is now ready for press.

8 Pro Tips for Murakami TXR

Distilled from Murakami’s TDS, professional shop experience, and our customer feedback. Save yourself the trial and error:

1
Coat 1+1 to Start, Then Build Up If Needed
Per Murakami TDS: apply one or two coats to the print side, rotate 180°, then one or two coats to the squeegee side. Additional coats may be added to the print side if thicker stencils are required.
2
Drying Position: Print Side Down
Per Murakami TDS, dry coated screens horizontally with the print side DOWN in a clean light-safe area. Gravity pulls excess emulsion toward the print side, building the sharp stencil profile.
3
Drying Conditions: 86-104°F, 30-50% Humidity
Per Murakami TDS, target 30-40°C (86-104°F) and 30-50% relative humidity for drying. A screen drying cabinet with heated airflow holds these conditions reliably.
4
Run a Stouffer Wedge Test on First Use
Per Murakami TDS, exposure is affected by mesh color, emulsion type, coating thickness, lamp type, and bulb age. The TDS exposure data is a starting point; a 21-step Stouffer wedge dials in your specific shop.
5
Use Hardener for Water-Based & Discharge Runs
Per Murakami TDS, TXR is suitable for water-based and discharge inks when hardened with Murakami MS Hardener or Hardener A&B. Skip the hardener and the stencil breaks down on long water-based runs.
6
Note: Hardener A&B Treated Screens Cannot Be Reclaimed
Per Murakami TDS: stencils treated with Hardener A&B will NOT be reclaimable. MS Hardener is reclaimable when proper procedures are followed. Choose based on whether you need to reclaim.
7
Coated Screens Last Up to 1 Month
Per Murakami TDS, coated screens may be stored for up to one month at 59-77°F (15-25°C), 30-50% relative humidity. Total darkness required.
8
Clean Film Positives Before Exposure
Per Murakami TDS, clean the film positives and vacuum frame glass before exposure to minimize pinholes. Frosted or weak-density positives reduce resolution.

Pair Murakami TXR With Murakami MS Hardener for Extended Runs

For water-based and discharge work running over a few hundred impressions, the stencil will gradually break down as the aqueous ink chemistry attacks the emulsion. Murakami MS Hardener is a post-exposure treatment that dramatically extends stencil life by cross-linking the cured emulsion for greater water, solvent, and abrasion resistance.

★ Murakami MS Emulsion Reclaimable Hardener

Applied after exposure, development, and blockout using a scoop coater on both sides. Cured in direct sunlight or a 100°F hot box. Compatible with diazo, dual-cure, and SBQ photopolymer emulsions across all major brands — so it works with Murakami TXR and every other Murakami emulsion.

Key benefit: Unlike permanent hardeners, MS Hardener is RECLAIMABLE when proper procedures are followed — meaning you don’t lose your screen inventory to the treatment. Ideal for water-based, discharge, and aggressive plastisol printing.

FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

What does pre-sensitized mean for Murakami TXR?
Pre-sensitized means the light-sensitive chemistry is already mixed into the emulsion at the factory. You don’t need to mix a separate diazo packet. Open the container, scoop, coat, expose, print. Compare to dual-cure emulsions like Photocure Pro that ship with a diazo packet you mix in at first use.
Why is Murakami TXR called “PVA-SBQ”?
PVA-SBQ stands for polyvinyl alcohol-styrylpyridinium. PVA is the base polymer; SBQ (styrylpyridinium) is the light-sensitive component that cures under UV. The SBQ-based pure photopolymer category was pioneered by Murakami over 30 years ago and is the foundation of nearly every modern pre-sensitized emulsion on the market.
How does Murakami TXR compare to dual-cure Photocure Pro?
See the comparison chart in the Description tab. Quick version: Murakami TXR is pre-sensitized PVA-SBQ photopolymer (no diazo mixing, faster exposure, but requires hardener for extended water-based or discharge runs). Photocure Pro is dual-cure (mix diazo at first use, broadest ink compatibility including solvent and UV inks). Choose Murakami TXR if you want simpler workflow and stick to textile inks; choose Pro if you need solvent/UV compatibility or want the widest exposure latitude.
How fast does Murakami TXR expose compared to diazo?
Per Murakami’s TDS, PVA-SBQ pure photopolymer emulsions like this one expose 3-5× faster than traditional diazo-based emulsions. The exact exposure time depends on your light source (metal halide vs LED), mesh count, mesh color, coating thickness, and bulb age. See the Technical Specs tab for the TDS exposure data as a starting point, then dial in with a Stouffer wedge test.
Do I need to use a hardener with Murakami TXR?
Not always. Per Murakami’s TDS, Murakami TXR is suitable for water-based and discharge inks WHEN HARDENED with Murakami MS Hardener or Hardener A&B. Without hardener, water-based and discharge ink chemistry will eventually break the stencil down on extended runs. For plastisol runs of any length, no hardener is required. For short water-based or discharge runs (under ~200 impressions), you may not need it. For extended water-based or discharge runs, the hardener is essential. View MS Hardener →
What’s the difference between MS Hardener and Hardener A&B?
Both are Murakami stencil hardeners that add water and solvent resistance. MS Hardener is single-part, applied with a scoop coater, and is RECLAIMABLE when proper procedures are followed — meaning you can still strip the stencil after using it. Hardener A&B is a two-part system that delivers maximum durability but is NOT reclaimable per Murakami’s TDS. Choose MS for screens you want to reclaim and reuse; choose A&B for screens you’re planning to retire or for single-use applications. MS Hardener · Hardener A&B
How long does Murakami TXR last in storage?
Unsensitized emulsion has a shelf life of at least 1 year at room temperature (per murakami tds). use murakami pva-sbq emulsion within one year for best results.. Coated unexposed screens last up to one month at 59-77°F (15-25°C), 30-50% relative humidity, in total darkness. Exposed (cured) stencils are stable indefinitely. Unlike dual-cure or diazo emulsions, pre-sensitized PVA-SBQ doesn’t have a separate sensitized shelf life since it ships already sensitized.
How thick should my stencil be?
For most textile work, one coat each side of Murakami TXR is sufficient. Per Murakami’s TDS, additional coats may be added to the print side or squeegee side if thicker stencils are required. For very high deposit work (puff plastisol, glitter ink, foil base), consider building up the squeegee side with multiple wet-on-wet coats, or use Chromaline Super PHAT capillary film bonded with Murakami TXR for 100-700µm stencil thickness.
What’s the right drying temperature and humidity?
Per Murakami’s TDS, target 86-104°F (30-40°C) ideal drying temperature at 30-50% relative humidity relative humidity, with good air circulation. A screen drying cabinet with heated airflow holds these conditions reliably. Drying temperatures over 104°F (40°C) can pre-cure the emulsion and cause exposure problems.
How do I reclaim a screen after using Murakami TXR?
Per Murakami’s TDS — (1) use Murakami 501, 505, or 507 Screen Cleaner to remove all excess ink from the frame; (2) remove the emulsion with Murakami 601, 605, or a solution of Strip Super-P; (3) rinse thoroughly; (4) use Murakami 701 to remove haze and ghost if required; (5) degrease with Murakami 801, rinse both sides thoroughly, and let dry. View screen cleaning chemicals →
What if my stencil washes out during exposure?
Most common cause: underexposure. Per Murakami’s TDS, exposure depends on mesh color, emulsion type, coating thickness, lamp type, and bulb age. Run a Stouffer wedge test to dial in correct exposure time for your specific shop. Other possible causes: emulsion that’s too thin (add more coats), light source too weak (consider upgrading to metal halide or LED), screen positioned too far from exposure source, or contaminated mesh (re-degrease and recoat). The Emulsion Troubleshooting Guide covers each scenario in detail.
What exposure unit do I need?
Per Murakami’s TDS, exposure data is provided for 5kw metal halide lamp at 40″ distance. LED UV exposure units also work well for PVA-SBQ emulsions like this one. Standard fluorescent exposure units can work but require longer exposure times. The exposure data in the Technical Specs tab is a starting point; a 21-step Stouffer wedge test takes 5 minutes and dials in your specific exposure unit accurately.
Why is the emulsion pink?
The pink color makes the stencil visible during coating (so you can see uneven coverage and fix it), during exposure registration (so you can align film positives accurately), and during reclaim (so you can see when the stencil is fully removed). Pure-clear or near-clear emulsions are harder to work with for these reasons. Murakami offers emulsions in blue, pink, violet, and magenta depending on the formulation.
Can I use this emulsion for water-based printing without a hardener?
Yes for short runs (under ~200 impressions) and for single-job use. Per Murakami’s TDS, Murakami TXR is suitable for water-based and discharge inks when hardened with Murakami Hardener and/or Hardener A&B for extended-run durability. Skip the hardener and the stencil chemistry will gradually break down as the aqueous ink attacks the emulsion. The decision is run length: short runs don’t need it, long runs benefit dramatically from it.
Is shipping really same-day?
Yes — Murakami TXR ships from RCS’s San Antonio, TX warehouse. Orders placed before 3:30 PM Central Time on a business day typically ship the same day. Most US destinations receive shipment in 2-5 business days via standard ground. FREE shipping on orders over $200. Need it faster? Call us at (512) 454-0505 for expedited shipping options.
