Clariant has 15 years technical experience in the use of crosslinkers for improving the paper wet surface strength and consequently the offset printing performances. Taylored made laboratory evaluations can be implemented in order to establish a diagnostic on the paper wet surface strength and eventually recommend the right insolubilizer with preferred addition levels. Clariant proposes a full range of insolubilizers from 3 different chemical families, which can cover most of the needs of the paper industry. paper Product Chemistry Patented Food contact Application Benefits technology compliance Cartabond TSI High – reactivity YES BfR 36 FDA 176.180 Uncoated and coated Multipurpose Glyoxal – based crosslinker offset printing paper, surface strength office paper, silicon- improver release, carbonless Resistance to high paper temperature and pH conditions in coating colour (resp. up to 70°C and 9.5) Cartabond EPI High – reactivity Glyoxal- YES BfR 36 Uncoated and coated Multipurpose based crosslinker FDA 176.180 offset printing paper, surface strength FDA 176.170 office paper, silicon- improver release, carbonless Optimized costpaper performance Cartabond MZI High – reactivity YES BfR 36 Coated offset printing Activated zirconium Ammonium Zirconium – FDA 176.180 paper (LWC, MWC) technology allows based crosslinker FDA 176.170 higher cost performance vs benchmark Cartabond KZI Starch YES BfR 36 Coated offset printing Activated zirconium Synthetic Latex FDA 176.180 paper (LWC, MWC) technology allows FDA 176.170 higher cost performance vs benchmark No ammonia smell colour chronicle 1 | 2009 21
