Franmar UN-Lok® Screen Unlocker – Rescue Locked Emulsion, Ghosting & Haze Without Remeshing

Franmar

Franmar UN-Lok® Screen Unlocker is the ultimate solution for screen printers dealing with locked emulsion, stubborn haze, ghost images, and capillary film failures. When emulsion dries, cures, or locks into the mesh beyond normal reclaiming, UN-Lok steps in to save the screen—often in 30 minutes or less.

This innovative gel-based screen unlocker penetrates deep into the mesh to break down hardened, unreclaimable emulsion without aggressive power washing or costly remeshing. Unlike liquid chemicals that run or dry too quickly, UN-Lok’s thick gel stays wet for up to 24 hours, giving you flexibility and extended dwell time for even the most extreme reclaim situations.

Designed to be safe on all mesh types, Franmar UN-Lok restores screens that would otherwise be considered lost, making it an essential problem-solver for any professional screen printing shop.

Price range: $20.50 through $321.00

Technical Specifications

Directions for Use:

  1. Preparation: Apply UN-Lok liberally to both the locked emulsion and the rest of the screen that requires cleaning.
  2. Dwell Time: Allow UN-Lok to sit on the screen surface for 10 to 30 minutes. For heavily locked areas, additional time may be needed.
  3. Scrubbing: Gently scrub the screen using a dedicated Biggee™ scrub pad to effectively break down the locked emulsion.
  4. Rinsing: Wash the screen thoroughly with a power washer or water hose equipped with a pressure nozzle, ensuring all unlocked emulsion is washed away.
  5. Repeat if Necessary: For particularly stubborn areas, feel free to repeat the application process with UN-Lok until your screen is fully restored.

Usage Tips:

  • UN-Lok can be left on screens overnight for even better results.
  • Check for loosened emulsion using a fingernail to ensure effective cleaning.
  • If desired, a degreaser can be used as a final cleaning step to leave your screens in impeccable condition.
