Murakami Emulsion Permanent Hardener A&B Quart Kit


Murakami AB Hardener is River City Graphic Supply’s most durable option for locking up your emulsion when printing long water based or discharge jobs. We recommend using this in conjuction with Murkami HV, Murakami HVP, or Murakami Photocure Pro emulsions.



SKU: MUR AB Hardener Categories: , ,


Hardeners A&B provide ultimate water resistance for waterbase and discharge ink systems. Mixed 1:1 and applied to the stencil after exposure, development, and drying. If emulsion is used as a block out it should be exposed prior to applying Hardeners A&B. After application the emulsion is semi permanent and may be hard to reclaim, especially on finer meshes. Designed for use in long run water base and discharge ink printing where ultimate screen durability is needed. Reclaiming is possible if HR-700 is used prior to applying emulsion remover.
