Murakami Emulsion Hardener Part B – Permanent Two-Part Stencil Hardener (Step 2)

Murakami Emulsion Hardener Part B is the critical second step in Murakami’s two-part permanent emulsion hardening system, designed for screen printers who require maximum stencil durability and water resistance. When used in combination with Murakami Part A, Part B chemically reinforces exposed emulsions to withstand the most demanding printing conditions.

This hardener is especially effective for water-based and discharge inks, as well as aggressive print environments involving high moisture, long runs, and elevated squeegee pressure. Shops printing with brands such as Printers Choice, Matsui, CCI, Magna, and Speedball rely on Murakami Part B to prevent stencil breakdown and maintain sharp image definition throughout production.

Part B penetrates and locks the emulsion structure, creating a hardened stencil that resists moisture, abrasion, and ink attack. While reclaiming is still possible, users should note that this is a permanent hardener and will significantly increase reclaim difficulty compared to reclaimable hardeners.

Murakami Emulsion Hardener Part B delivers uncompromising stencil strength for shops that prioritize durability and print consistency—making it an essential component of Murakami’s permanent hardening system.

Technical Specifications

Directions to Apply Murakami Emulsion Hardener for Enhanced Screen Strength (Water-Based & Discharge Printing):

  1. Preparation: Ensure that the screen is coated with a suitable emulsion and has been exposed and dried according to the emulsion manufacturer’s guidelines. The emulsion should be fully dry and ready for further treatment.
  2. Mixing: Prepare the emulsion hardener according to the manufacturer’s recommended mixing ratios. Use precise measurements to achieve the desired strength and durability.
  3. Thorough Stirring: Stir the emulsion hardener mixture thoroughly to ensure even distribution of the hardener throughout the solution.
  4. Screen Coating: Apply the emulsion hardener mixture to both sides of the dry screen using a clean coating trough or scoop coater. Ensure that the hardener covers the entire screen surface evenly for consistent results.
  5. Drying: Allow the emulsion hardener to dry on the screen. Follow the recommended drying time provided by the manufacturer. Proper drying is essential for the hardener to bond effectively with the emulsion.

Note: Please be aware that the use of emulsion hardener may make the emulsion difficult to reclaim from the screens. Due to the enhanced durability, the emulsion may not break down as easily during the reclaiming process. Proper handling and disposal procedures should be followed according to local regulations.

By following these instructions, you can strengthen your screens for water-based and discharge printing applications. The emulsion hardener will provide increased durability and water resistance, allowing you to achieve high-quality and long-lasting prints with confidence. However, remember the note regarding the reclaiming difficulty, and take necessary precautions to handle and dispose of the emulsion properly. Embrace the power of emulsion hardener to elevate your screen printing and create screens that can withstand the challenges of water-based and discharge inks.
