About
A fluorinated polyurethane polymer with film-forming properties, whose environmental and regulatory profile raises moderate concerns.
Polyurethane-27 is a complex polymer incorporating polyperfluoroethoxymethoxy difluorohydroxyethyl ether and isophorone diisocyanate (IPDI), further reacted with a triethylamine salt. The restriction note references 'ban substances that deplete the ozone layer,' suggesting perfluoroether components that have faced environmental phase-outs (e.g., PFOS, PFOA-related compounds). While not a direct CMR (Carcinogenic, Mutagenic, or toxic to Reproduction) classification under EU law, the perfluorinated moiety places this ingredient in a higher-scrutiny category, with an EU regulatory flag that warrants caution.
