Aromatic Diisocyanates ChemWipe Surface Contamination Detection

The 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 unique design of the aromatic diisocyanates ChemWipe provides uniform color change formation enabling user to quantify aromatic diisocyanates contamination using the color comparator (PN: 304-6000). 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.
