Murakami MS Emulsion Reclaimable Hardener – Post-Exposure Stencil Hardener for Screen Printing
Murakami
Murakami MS Emulsion Reclaimable Hardener is a post-exposure stencil hardener that dramatically increases water resistance, solvent resistance, and abrasion resistance — while remaining reclaimable when proper procedures are followed. Applied after exposure, development, and blockout using a scoop coater on both sides, then cured in direct sunlight or a 100°F hot box. Compatible with diazo, dual-cure, and SBQ photopolymer emulsions across all major brands. Ideal for water-based, discharge, and aggressive plastisol printing.

Description
More Durable Stencils. Still Reclaimable.
Murakami MS Hardener is the choice when you need tougher stencils for water-based and discharge printing but still plan to reclaim and reuse your screens. It works across diazo, dual-cure, and SBQ photopolymer emulsions — regardless of brand.
Key Features
♻️
Reclaimable
Unlike permanent hardeners, MS Hardener allows screens to be reclaimed after printing when proper procedures are followed — preserving your screen inventory while still getting significantly better stencil durability.
🧪
Cross-Brand Emulsion Compatible
Works with diazo, dual-cure, and SBQ photopolymer emulsions across all major brands, not just Murakami. One hardener for your entire emulsion line.
💧
Water & Abrasion Resistance
Significantly improves stencil resistance to moisture, solvents, and squeegee abrasion — reducing edge breakdown and on-press touch-ups during long runs.
☀️
Curing Required
After application, the screen must be cured in direct sunlight or a 100°F hot box. This step activates the hardening agents and is required for maximum performance.
How to Apply
Complete all standard screen prep steps — exposure, washout, blockout — before applying hardener. Screen must be fully dry before hardener application.
Using a clean lint-free cloth, soft brush, or sponge, apply a thin, even layer of hardener to both sides of the screen. Ensure complete, uniform coverage.
Place the treated screen in direct sunlight or a controlled 100°F hot box. This curing step is required — it activates the hardening agents and determines final stencil strength.
Follow the dwell time specified in the manufacturer’s instructions before proceeding to press.
The hardened stencil is ready for press. Expect significantly improved resistance to moisture, abrasion, and stencil breakdown.
Reclaim the screen promptly after printing using appropriate reclaim chemistry and proper procedures. MS Hardener increases reclaim difficulty — prompt reclaiming reduces this.
⚠️ Reclaiming Is More Difficult After Hardening
MS Hardener increases the water and solvent resistance of the emulsion, which also makes it harder to break down during reclaiming compared to untreated stencils. Follow proper reclaim procedures and use appropriate stencil remover chemistry. Reclaim promptly after printing for best results.

Murakami Hardener Comparison
Murakami makes three hardener products that are often confused. Here’s how they differ and when to use each one.
| Product | Type | How to Use | Reclaiming | Best For |
|---|---|---|---|---|
| MS Hardener | Reclaimable One-part | Apply alone with scoop coater to both sides. Cure in sunlight or 100°F hot box. | More difficult than untreated — but still reclaimable with proper chemistry | Tougher stencils for long runs while still reclaiming screens regularly |
| Part A (included in A&B Kit) | Reclaimable Two-part, Step 1 | Apply first with scoop coater to both sides. Air dry or hot box. Part B follows. | Reclaimable on its own — becomes permanent once Part B is applied | Step 1 of the permanent hardening process — must be followed by Part B to achieve maximum durability |
| Part B (sold separately) | Permanent Lock Two-part, Step 2 | Apply after Part A has dried. Scoop coater to both sides. This step permanently locks the emulsion. | Permanently locked — significantly harder to reclaim | When maximum durability is needed and reclaiming difficulty is acceptable. Sold separately for restock. |

FREQUENTLY ASKED QUESTIONS
What makes MS Hardener different from the Murakami A&B Permanent Hardener?
MS Hardener is a reclaimable hardener — it significantly increases stencil water and abrasion resistance while still allowing screens to be reclaimed with standard stencil removers when proper procedures are followed. The Murakami A&B Permanent Hardener is a two-part permanent system that delivers even greater durability, but makes reclaiming significantly harder. Choose MS Hardener when you need tougher stencils but still plan to reclaim. Choose A&B when maximum durability matters more than reclaim convenience.
What emulsion types is MS Hardener compatible with?
Compatible with diazo, dual-cure, and SBQ (pure photopolymer) emulsions across all major brands — not just Murakami. This makes it a versatile solution for shops using different emulsion systems.
How do I apply Murakami MS Hardener?
After the screen is exposed, developed, blocked out, and fully dried, apply MS Hardener evenly to both sides of the screen using a clean coating trough or scoop coater. Then cure by placing in direct sunlight or a 100°F hot box. Follow the dwell time specified in the manufacturer’s instructions before printing.
Does it require a curing step after application?
Yes. After applying MS Hardener, the screen must be cured — either in direct sunlight or in a 100°F hot box. This curing step activates the hardening agents and is critical for achieving maximum water resistance.
Can reclaiming become more difficult after using MS Hardener?
Yes. While MS Hardener is described as reclaimable, the emulsion will be harder to break down than untreated emulsions. Follow proper reclaim procedures and use appropriate reclaim chemistry. Prompt reclaiming after the print job is recommended.
