The Aromatic Diisocyanates ChemWipe PN: 304 is a colorimetric surface wipe designed to provide real-time indication of the presence of trace amounts of aromatic diisocyanates on surfaces. The ChemWipe is selective and sensitive. The unique design of the ChemWipe provides uniform color change formation enabling user to quantify chemical contamination using the color comparator.

Aromatic diisocyanates include toluene 2,4-diisocyanate (2,4-TDI), toluene 2,6-diisocyanate (2,6-TDI) and 4,4'-methylene diphenyl diisocyanate (MDI). The ChemWipe detects monomers and oligomers.
