Murakami MS Emulsion Reclaimable Hardener
Murakami
Give your stencils the durability needed for tough runs—without locking them on the frame. Murakami MS Hardener is a reclaimable post-exposure hardener that boosts water, solvent, and abrasion resistance for long prints, higher squeegee pressure, and inks that are hard on emulsions (water-based, discharge, and additized plastisols). It’s compatible with all major emulsion chemistries—diazo, dual-cure, and pure photopolymer (SBQ)—not just Murakami brands.

Description
Murakami MS Emulsion Reclaimable Hardener Key Features:
- Unmatched Water Resistance: Murakami MS Hardener fortifies your stencils against moisture, delivering unrivaled water resistance for water-based and discharge printing applications. No more worries about ink breakdown due to environmental factors.
- Simple Application: This easy-to-use emulsion hardener is applied to both sides of the screen after the exposure, development, and blocking stages. Its user-friendly application ensures seamless integration into your screen printing process.
- Reclaimable Stencils: Despite its water-resistant properties, Murakami MS Hardener allows for the efficient reclaiming of your screens when following proper process techniques. Reuse your screens with ease, saving time and resources.
- Optimum Results: For peak performance, place the treated screen in direct sunlight or a 100-degree hot box. This step optimizes the hardener’s efficacy, delivering sturdy stencils ready for demanding printing tasks.

Technical Specifications
Directions to Use Murakami MS Hardener for Stencil Hardening (Water-Based & Discharge Printing):
- Preparation: Ensure that the emulsion-coated screen has been properly exposed, developed, blocked out, and thoroughly dried before proceeding with the application of Murakami MS Hardener.
- Handling Precautions: Always wear protective gloves and eye protection when handling the hardener to ensure safety during the application process.
- Application: Apply Murakami MS Hardener to both sides of the dry, exposed emulsion using a clean coating trough or scoop coater. Ensure even coverage across the entire screen surface to achieve consistent hardening.
- Curing: After applying the hardener, place the treated screen in direct sunlight or a controlled environment such as a 100-degree hot box for optimal results. This curing process activates the hardening agents in the emulsion, enhancing water resistance.
- Dwell Time: Allow the hardener to dwell on the screen for the recommended time, as provided by the manufacturer. Adequate dwell time is crucial to ensure the emulsion hardens properly for water-based and discharge printing.
- Post-Curing: After the dwell time has elapsed, thoroughly rinse both sides of the screen with water to remove any excess hardener.
- Reclaiming: It is essential to note that while Murakami MS Hardener enhances the water resistance of the emulsion, it can also make the stencil more challenging to reclaim. To ensure ease of reclaiming, follow proper screen cleaning procedures and use appropriate reclaiming chemicals.
Important Note: Following the recommended process techniques and adhering to the dwell time is crucial to achieving the desired water resistance for water-based and discharge printing. However, keep in mind that the emulsion will become more difficult to reclaim once the hardener is applied. Proper handling, disposal, and safety precautions should be observed when using this product.
