Maximum Durability for Water-Resistant Screen Stencils Kiwo Hardener WR is a professional-grade chemical hardener specifically engineered to maximize the water resistance of photo emulsions. Designed for high-demand screen printing environments, this reclaimable hardener ensures your stencils withstand the rigors of long production runs without compromising the ability to clean your screens later. Why Choose KIWO Hardener WR? Enhanced Water Resistance: Chemically crosslinks with emulsions to provide superior protection against water-based inks and abrasive media. Reclaimable Formula: Unlike permanent stencil hardeners, Hardener WR is designed to be reclaimable, allowing for screen reuse after a slightly longer reclaiming process. Wide Compatibility Improved Stencil Longevity: Prevents stencil breakdown during extended print cycles, saving time and reducing screen remakes. Technical Specifications & Application Appearance: Clear liquid chemical hardener. Application Method: Apply generously with a sponge or rag to both sides of a dry or slightly damp imaged screen. Reaction Time: Allow the hardener to react for several minutes to ensure full absorption into the emulsion. Post-Treatment: For best results, ensure the hardener has completely evaporated from the open mesh areas before printing. Product Details Primary Use: Stencil hardening for water-based screen printing. Safety: Always refer to the Technical Information Sheet for specific emulsion compatibility and safety protocols.
