Function tag evidence & scope

Function tags help find candidates. They do not establish suitability for water-based paint or an EcoSafe rating.

At a glance for your formula

Evonik TEGO Wet 270 eCO is a polyether-siloxane substrate wetting agent offered as a mass-balance alternative to TEGO Wet 270. The supplier reports retained performance with reduced carbon emissions and broad use in waterborne, solventborne and radiation-curing coatings. It can support crater prevention, but its sourcing claim does not establish physical biobased content or biodegradability. Compatibility with the starter wetting agent remains a trial question.

Grade-specific screening values have not been recorded. Consult the selected supplier’s technical reference.

3 of 16 defined fields are recorded with a source. This measures structured information currently on this site, not the completeness of every linked PDF. Missing fields remain in the denominator.

Coverage is separate from scientific accuracy, human verification and EcoSafe assessment. Molecular fields may not apply to a grade or family; they are not filled from another material to increase its score.
