Murakami 605 Emulsion Remover – Super-Concentrated 1:30 Emulsion Remover for Screen Printing
Murakami
Murakami ER-605 is a super-concentrated emulsion remover that works two ways — spray it directly on the screen for manual reclaim, or dilute it into a dip tank for hands-off batch reclaiming. At a 1:30 dilution ratio (1 part concentrate to 30 parts water), one gallon goes a long way. Formulated with built-in cleaning agents and degreasers, it breaks down photopolymer, diazo, and capillary film emulsions cleanly. For hardened screens from water-based or discharge printing, use it at a stronger concentration. Safe on all mesh types. Drain safe.

Murakami ER-605 — Super-Concentrated Emulsion Remover for Manual Spray & Dip Tank Use
ER-605 gives you two reclaiming workflows in one concentrate. Spray it on for standard manual screen reclaim, or dilute it into a dip tank for batch-mode reclaiming where screens soak and release emulsion passively. The 1:30 dilution ratio makes it one of the most economical emulsion removers on the market — one gallon of concentrate fills a standard 30-gallon dip tank. Built-in degreasers clean the mesh in the same step. Works on photopolymer, diazo, and capillary film. Use it at higher concentration for hardened WB and discharge screens. Drain safe. Safe on all mesh types.
1:30 Dilution — Exceptional Economy
One part concentrate to 30 parts water. One gallon of ER-605 makes 31 gallons of working solution. For a 30-gallon dip tank, you need just 1 gallon of concentrate. The cost per screen is dramatically lower than RTU emulsion removers.
Two Use Modes: Manual + Dip Tank
Most emulsion removers are designed for one application method. ER-605 handles both — spray or brush the diluted solution onto the screen for manual reclaim, or fill a dip tank for automated batch processing. Same product, same dilution, different workflow.
Photopolymer, Diazo & Capillary Film
Works on all major emulsion types used in professional screen printing. Photopolymer, diazo, dual-cure, and capillary film stencils all break down under ER-605 chemistry.
Built-In Degreasers
The cleaning additives and built-in degreasers in ER-605 do double duty — emulsion removal and mesh degreasing in one step. Screens come out cleaner and more ready for recoating than with basic emulsion removers.
Adjustable Concentration for Hardened Screens
For water-based or discharge ink shops where emulsions get harder and more resistant, mix ER-605 at a stronger concentration than 1:30. More concentrate = more power. Murakami specifically notes this for WB and discharge hardened screens.
Safe on All Mesh Types
Non-aggressive chemistry that won’t damage polyester or nylon mesh fibers. Use it on any mesh count without concern for fiber degradation.
Drain Safe
Drain safe under standard conditions. Always verify with your local waste authority for specific disposal requirements in your area.
Not for Auto Reclaim Machines
ER-605 foams during use. This makes it unsuitable for automated reclaiming machines with recirculation pumps. Use it manually or in a standard dip tank.

Then pressure rinse
Method 1 — Manual Spray Application
For reclaiming individual screens by hand in your washout booth:
Step 1 — Remove Excess Ink
Scrape or card excess ink off the screen. The less bulk ink present, the more effectively ER-605 works on the emulsion.
Step 2 — Dilute the Concentrate
Mix 1 part ER-605 with 30 parts water in a spray bottle or bucket. For hardened screens (WB/discharge), use a stronger ratio — 1:20 or 1:15.
Step 3 — Apply to Screen
Apply the diluted solution to both sides of the screen using a spray bottle, brush, or scrub pad. Ensure full coverage of the emulsion area.
Step 4 — Dwell 30–60 Seconds
Allow the solution to penetrate the emulsion for 30–60 seconds. For thicker emulsion coatings or hardened screens, allow up to 2 minutes.
Step 5 — Scrub Both Sides
Scrub both sides of the screen with a brush or scrub pad to help break down the emulsion. Work the solution into the mesh.
Step 6 — High-Pressure Rinse
Rinse both sides thoroughly starting from the bottom with a high-pressure washer. All emulsion residue should wash away cleanly.
Method 2 — Dip Tank Batch Reclaiming
For soaking multiple screens simultaneously in a dip tank — ideal for high-volume production shops:
Step 1 — Prepare the Tank
Fill the dip tank with water. Add ER-605 at a 1:30 ratio — for a 30-gallon tank, add 1 gallon of ER-605 to 30 gallons of water. Mix thoroughly.
Step 2 — Remove Excess Ink
Before submerging, remove as much ink as possible from the screen. Bulk ink in the tank depletes the solution faster and reduces its effectiveness.
Step 3 — Submerge the Screen
Lower the screen into the dip tank, ensuring the mesh is fully submerged in the solution. Screens can be stacked if the tank allows.
Step 4 — Soak 2–5 Minutes
Allow screens to soak for 2–5 minutes depending on emulsion thickness and age. The emulsion will begin to soften and loosen from the mesh.
Step 5 — Remove & Drain
Lift the screen out and allow excess solution to drain back into the tank. This recovers chemistry and allows additional working time on the emulsion.
Step 6 — High-Pressure Rinse
Pressure wash both sides of the screen to fully remove loosened emulsion. Start from the bottom and work up for best results.
Dip Tank Maintenance
Replace the tank solution when it becomes heavily loaded with emulsion solids and cleaning performance drops. Always check local regulations for disposal.
🧪 Dilution Guide
| Use Case | Ratio | Notes |
|---|---|---|
| Standard reclaim | 1:30 | 1 part concentrate + 30 parts water |
| Dip tank fill | 1:30 | 30-gal tank: 1 gal concentrate + 30 gal water |
| WB/discharge hardened | 1:15–1:20 | Stronger for difficult emulsions |
| Very stubborn screens | 1:10 or less | Maximum strength — use sparingly |
⚠️ Important Notes
Not for auto reclaim machines. ER-605 foams during use. This foaming will cause problems with recirculation pumps and nozzles in automated reclaiming equipment. Use only in manual spray application or standard dip tanks.
Dip tank caution. Don’t over-soak screens. Extended soak times can loosen the adhesive bond between mesh and frame. 2–5 minutes is sufficient for most screens.
Drain safe under standard conditions. Always check with your local waste authority for disposal requirements in your area.

FREQUENTLY ASKED QUESTIONS
What is the dilution ratio for standard use?
1 part ER-605 concentrate to 30 parts water. For a 30-gallon dip tank, that means 1 gallon of concentrate plus 30 gallons of water. For manual spray application, mix the same ratio in a spray bottle or bucket.
Can I use ER-605 in a dip tank?
Yes. This is one of ER-605’s primary use cases. Dilute 1:30, fill your dip tank, and submerge screens for 2–5 minutes depending on emulsion thickness. Remove, drain back into the tank, then rinse with high-pressure water. Note: ER-605 is not suitable for automated reclaiming machines with recirculation pumps due to foaming.
What’s the difference between spray application and dip tank use?
Spray application: dilute, apply directly to the screen, let dwell 30–60 seconds, scrub, and pressure rinse. Good for individual screens and shops without a dip tank. Dip tank: fill the tank with diluted solution, submerge screens, soak 2–5 minutes passively, then remove and rinse. The dip tank method is more hands-off and better for processing multiple screens simultaneously.
My screens use water-based or discharge inks and the emulsion is hard to remove. What do I do?
Use ER-605 at a stronger concentration. Murakami specifically notes that ER-605 can be mixed more concentrated for additional strength when reclaiming hardened screens from WB and discharge textile printing. Try 1:20 or 1:15 as a starting point. Increase strength as needed.
Why can’t I use ER-605 in an automatic reclaiming machine?
ER-605 foams during use. Automated reclaiming machines with recirculation pumps and spray nozzles are not designed to handle foaming chemistry — the foam creates air pockets, reduces cleaning performance, and can damage the equipment. Use ER-605 only in manual spray application or standard dip tanks.
Does ER-605 remove ink as well as emulsion?
ER-605 is primarily an emulsion remover with built-in cleaning additives and degreasers. It will help with residual ink during the emulsion removal process, but for heavy ink deposits, remove as much ink as possible before applying ER-605. For a dedicated ink + emulsion one-step product, consider a dip tank solution like Easiway 500.
Is ER-605 safe for all mesh types?
Yes. Murakami formulates ER-605 to be safe on all mesh types — polyester and nylon at any thread count.
What sizes does River City Supply stock?
We stock Murakami ER-605 in quart, gallon, and 5-gallon pail. Same-day shipping on in-stock orders placed before 3:30 PM CT from San Antonio, TX. Free shipping on orders over $200.
