AB screen emulsion hardener
- Strengthens emulsion stencils
- Helps improve screen durability
- Two easy-to-mix components
- 1:1 mixing ratio
Product details
AB screen emulsion hardener is a screen treatment chemical consisting of two components, MA and MB. It strengthens the emulsion stencil and helps maintain screen durability during printing.
In screen printing, two-component stencil hardeners are commonly used to improve the durability and water resistance of compatible emulsion stencils. Treatment effectiveness depends on the emulsion and application procedure.
Product Features
1. Two-Component Hardening System
MA and MB solutions are mixed before use to prepare the emulsion stencil treatment solution.
2. 1:1 Mixing Ratio
Mix the two components in equal proportions. Follow the specified ratio; do not increase or reduce either component arbitrarily.
3. Defined Mixed-Solution Working Life
The mixed solution must be used within 48 hours. Prepare only the quantity needed to minimize unused solution exceeding its working life.
4. No Metal Mixing Tools
Do not use metal tools when combining or stirring the solutions, as specified in the product instructions.

Mixing Instructions
▫ Step 1: Prepare a suitable container and stirring tool. Do not use metal tools.
▫ Step 2: Add MA and MB solutions at a 1:1 ratio to the container.
▫ Step 3: Stir thoroughly before use.
▫ Step 4: Record the mixing time and use the solution within 48 hours. Do not reuse any solution that has exceeded this period.
Applications
For treating and strengthening emulsion stencils requiring improved durability. Check compatibility with the emulsion in use before treating the entire screen.
Precautions for Use
The available documentation does not specify whether the 1:1 ratio is by weight or by volume. Confirm the measuring method before mixing.
Application method, dwell time, and drying conditions must follow the instructions specific to the MA/MB system. Do not apply processing parameters specified for other hardeners.
Some hardeners can make emulsion stencils difficult or impossible to remove for mesh reuse. Check stencil reclaimability after treatment if the mesh needs to be reclaimed.
