Murakami Emulsion Permanent Hardener A&B Quart Kit – Two-Part Stencil Hardener for Extreme Durability

The Murakami Emulsion Permanent Hardener A&B Quart Kit is a high-performance, two-part hardening system engineered for screen printers who need maximum stencil durability and water resistance. Designed for the most demanding printing conditions, this permanent hardener dramatically strengthens exposed emulsions to withstand water-based inks, discharge inks, high humidity, and long production runs.

Using a sequential Part A and Part B application, this system chemically reinforces the emulsion, creating a highly resistant stencil capable of handling aggressive printing environments and repeated wash cycles. It is especially well suited for shops running water-based or discharge inks where untreated emulsions may soften or break down prematurely.

Murakami A&B Permanent Hardener is compatible with a wide range of emulsion types and integrates easily into professional screen prep workflows. While reclaiming is still possible when proper procedures are followed, users should note that permanent hardening significantly increases reclaim difficulty compared to reclaimable hardeners.

Description

Murakami Emulsion Permanent Hardener A&B Quart Kit Key Features & Benefits:

  • Two-part permanent emulsion hardening system (Part A & Part B)
  • Dramatically increases stencil durability and water resistance
  • Ideal for water-based and discharge screen printing
  • Helps prevent stencil breakdown in high-humidity environments
  • Strengthens emulsions for long print runs and aggressive inks
  • Compatible with most photo, dual-cure, and diazo emulsions
  • Applied after exposure and drying for maximum performance
  • Designed for professional and high-production screen printing shops

Important Use Notes:

  • This is a permanent hardener and will make reclaiming more difficult
  • Proper reclaim chemistry and dwell time are required
  • Always follow Murakami’s application order, dwell times, and safety instructions

Ideal For:

  • Water-based and discharge printing
  • Long production runs
  • High-humidity screen rooms
  • Printers needing maximum stencil strength

The Murakami Emulsion Permanent Hardener A&B Quart Kit is the right choice when stencil longevity matters more than easy reclaiming—delivering unmatched resistance, reliability, and performance for serious screen printing operations.

Technical Specifications

Instructions for Using Murakami Part A and Part B Emulsion Hardeners to Strengthen Exposed Screens for Water-Based and Discharge Inks:

Before You Begin: Ensure that your emulsion-coated screen has been properly exposed, developed, and thoroughly dried before proceeding with the application of Murakami Part A and Part B Emulsion Hardeners.

Handling Precautions: Always wear protective gloves and eye protection during the application process to ensure safety.

Part A Application:

  1. After the screen’s emulsion and image have been properly exposed, apply Murakami Part A Emulsion Hardener to both sides of the screen using a clean coating trough or scoop coater.
  2. Ensure even coverage across the entire screen surface, as this will contribute to the consistent hardening of the emulsion.
  3. Allow the screen to air dry or use a controlled environment like a 100-degree hot box for optimal results. The dwell time for Part A will depend on the specific product instructions from the manufacturer.

Part B Application:

  1. After the dwell time for Part A has elapsed, apply Murakami Part B Emulsion Hardener to both sides of the screen in the same manner as Part A. Ensure even coverage to achieve uniform hardening.
  2. Once again, allow the screen to air dry or use a controlled environment for optimum results. The dwell time for Part B will also depend on the specific product instructions from the manufacturer.

Note: It is crucial to follow the recommended dwell times for both Part A and Part B, as provided by the manufacturer, to achieve the desired level of screen strength and water resistance.

Post-Treatment: After completing the application of both Part A and Part B Emulsion Hardeners, your screen will exhibit enhanced water resistance and durability, making it ideal for water-based and discharge ink printing.

Screen Reclaiming Considerations: It’s important to note that while the emulsion will become stronger and more resistant to water and ink degradation, it may also become more challenging to reclaim after using Part A and Part B Emulsion Hardeners. Ensure you follow proper screen cleaning and reclaiming techniques to maintain reclaimability without compromising the hardening benefits.

With Murakami Part A and Part B Emulsion Hardeners, you can confidently create screens that withstand the rigors of water-based and discharge ink printing, producing high-quality, durable prints with ease. Trust in Murakami’s advanced emulsion hardening system to elevate your screen printing game and deliver exceptional results for your creative projects.
