Technical InformationKIWOCOL ® POLY-PLUS SWRPage 2 of 2Update: 02/18/108. POST-EXPOSUREPost-exposing the screen after developing and drying is not veryeffective. To improve the resistance 10-15% the post-exposure timeneeds to be four times the original exposure time. Exposing thescreen fully with the primary exposure offers better resistance thanunder exposing initially, then post-exposing to improve resistance.Post exposure is most often used for long printing runs when waterbased and/or abrasive inks are used.9. POST-HARDENING (CHEMICALLY)The emulsion can be chemically post-hardened using one of KIWO’sstencil hardeners. Stencil hardeners can be classified as reclaimableor un-reclaimable.If reclaiming ability is desired, use KIWO HARDENER WR orHARDENER HP.If a permanent un-reclaimable stencil is desired, for example whencataloging screens for future use, or when aggressive inks are usedfor very large print runs, use KIWO HARDENER K. See separateTechnical Information sheets for further details regarding KIWO’sstencil hardeners.effective ink ghost removal, HAZE REMOVER can be used inconjunction with KIWOCLEAN ® CONCENTRATED INK WASH orULTIMATE INK WASH to re-activate dried HAZE REMOVER.Active components in FAST LIQUID HAZE REMOVER and MEGACLEAN ACTIVE work in approximately five minutes and effectivelyremove both emulsion haze and ink ghost simultaneously. Seeseparate Technical Information sheets for further details regardingKIWO’s haze removers.Haze removers, like ink washes and stencil removers should beworked into the screen mesh from both sides of the screen beforeremoving for maximum effectiveness.13.

BLOCKOUT / TOUCH-UPPotlife:4-6 weeks at 68°F/20°CWhen printing with plastisol, UV and solvent-based inks, retouchingand blocking out can be done with KIWO’s BLOCKOUT, REDBLOCKOUT or KIWOFILLER SR 401 NV. For a water resistancestencil, block out and retouch with KIWOFILLER SWR 22 or useKIWOCOL ®POLY-PLUS SWR (dry thoroughly and re-exposecompletely prior to using stencil hardeners). See separate TechnicalInformation sheets for further details regarding KIWO’s blockouts.11. RECLAIMINGKIWOCOL ®POLY-PLUS SWR can be reclaimed with KIWO’sSTENCIL REMOVER 1:20 CONCENTRATE. Before reclaiming, ensurethe screen is completely cleaned of ink or ink cleaning chemicalresidues. If water beads up on the stencil, residues are still present.If this is the case, degrease the screen again prior to reclaiming forbest results.For best results, work both sides of the screen i.e. apply stencilremover, brush, and pressure wash both sides of the screen. Afterapplying stencil remover, a short dwell time may be used prior topressure washing to allow more working time for the stencil removerespecially when using coarser meshes and/or thicker stencils.CAUTION: Never allow stencil removers to dry prior to removal, asthe emulsion will become locked into the mesh and virtuallyimpossible to remove.Pre-coated screens: 1-3 weeks in completedarkness at 68°F/20°CFreezing:VOC:TLV:protect against freezingnoneN/AHMIS rating: Health – 1Flammability – 0Reactivity – 014.

HAZE REMOVINGTo remove emulsion haze or ghost images left from the ink, useKIWO’s HAZE REMOVER, FAST LIQUID HAZE REMOVER, orMEGA CLEAN ACTIVE.For best results, HAZE REMOVER should be applied to a dryscreen, then allowed to completely dry on the screen.
