Outstanding Resolution & Definition
Holds fine lines, halftones, and detailed artwork. The SBQ chemistry produces sharper stencil shoulders than diazo-based formulations.

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 T9 Pink 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 T9 Pink Is Used For

Murakami T9 Pink 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:

High-Volume Production Shops
Pre-sensitized chemistry means no waiting for diazo to mix into the emulsion. Shops doing daily screen-making cycles save the setup step every batch.
Water-Based and Discharge Textile Printing
T9 Pink handles water-based and discharge inks. For extended runs over 200 impressions, pair with Murakami MS Hardener for additional water resistance.
High Solid Acrylic (HSA) Inks
Specifically rated for HSA — the thick, high-coverage acrylic inks used for poster and apparel work. Not every emulsion handles HSA chemistry; T9 Pink does.
Mixed-Ink Workflow Shops
Plastisol Monday, water-based Tuesday, discharge Wednesday. One emulsion inventory line handles all three with pre-sensitized convenience.
Fine Halftone & Detail Work
PVA-SBQ chemistry produces sharper edges than diazo. Holds halftones cleanly without dot gain or detail loss.
LED and Metal Halide Exposure Units
The TDS provides exposure data for 3kW Metal Halide at 12mW/cm² UV42 intensity. T9 Pink works on standard exposure units across the price range.
Shops Transitioning Off Diazo
If you’re tired of mixing sensitizer and tracking sensitized shelf life, T9 Pink is the natural upgrade path. Same Murakami quality, faster workflow.

Step-by-Step: Coating & Exposing Murakami T9 Pink

Murakami T9 Pink 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 T9 Pink 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 Up to 104°F (40°C) maximum and 30-50% relative humidity ideal 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 T9 Pink

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

1
Coat 1+1 First, Add Wet-on-Wet to the Squeegee Side
Start with one coat each side. For thicker EOM (Emulsion Over Mesh), add additional wet-on-wet coats to the SQUEEGEE side only. Print-side coats are what define edge sharpness; squeegee-side coats add deposit thickness.
2
One Coat Each Side = Four Diazo Coats
Per Murakami’s TDS, T9 Pink at 44% solids builds equivalent stencil thickness in one coat each side to four wet-on-wet coats of standard diazo emulsion. You’ll likely need fewer coats than you’re used to.
3
Drying Position: Print Side Down
Always dry coated screens flat with the PRINT SIDE FACING DOWN. Gravity pulls excess emulsion toward the print side, building the desired sharp-edged stencil profile.
4
Run a Stouffer Wedge Test on First Use
Every shop’s exposure unit is different. A 21-step Stouffer wedge test tells you your specific shop’s optimal exposure within 5 minutes. Use the TDS exposure data as a starting point, then fine-tune.
5
Filter the Emulsion Before Use
Per Murakami’s TDS, filter T9 Pink through screen mesh before pouring back into the container. Removes dust, foreign substances, and air bubbles that cause coating defects.
6
Use Hardener for Long Water-Based Runs
T9 Pink handles water-based and discharge inks well. For runs over 200 impressions, applying MS Hardener after exposure adds dramatic durability. Hardener is reclaimable when proper procedures are followed.
7
Keep the Emulsion Cool and UV-Safe
Per Murakami’s TDS, store emulsion in a cool, UV-light-safe area. Avoid temperature swings (don’t store in a garage that gets hot in summer). Heat and light shorten shelf life.
8
Drying Temperature Stays Below 104°F (40°C)
Per the TDS, drying temperature should not exceed 40°C/104°F. Excessive temperatures pre-cure the emulsion and cause exposure problems. Most home heating + air movement is plenty.

Pair Murakami T9 Pink 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 T9 Pink 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 T9 Pink?
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 T9 Pink 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 T9 Pink compare to dual-cure Photocure Pro?
See the comparison chart in the Description tab. Quick version: Murakami T9 Pink 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 T9 Pink 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 T9 Pink 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 T9 Pink?
Not always. Per Murakami’s TDS, Murakami T9 Pink 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 T9 Pink last in storage?
Unsensitized emulsion has a shelf life of up to 1 year at room temperature, sealed in original container. 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.
Can Murakami T9 Pink freeze?
Per Murakami documentation, T9 emulsion can be affected by freezing temperatures. During winter months, inventory may be lower and shipping could be delayed to prevent freeze damage. If you’re in a cold-weather region and ordering between December and March, expedited shipping is recommended to minimize transit time. Store the emulsion above freezing once it arrives.
How thick should my stencil be?
For most textile work, one coat each side of Murakami T9 Pink 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 T9 Pink for 100-700µm stencil thickness.
What’s the right drying temperature and humidity?
Per Murakami’s TDS, target Up to 104°F (40°C) maximum drying temperature at 30-50% relative humidity ideal 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 T9 Pink?
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 3kw metal halide lamp (uv42 intensity: 12 mw/cm²). LED UV exposure units also work well for PVA-SBQ emulsions like Murakami T9 Pink. 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 T9 Pink 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 T9 Pink 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.
