| Abstract |
The effect of toluenediamine (TDA), and a range of solvents and catalysts, on the measurement of tolylene diisocyanate (TDI) concentrations using a commercially available impregnated paper tape was evaluated. Low concentrations of TDA occurs as a hydrolysis product of TDI in polyurethane-producing factory atmospheres, produced a significant attenuation in the stain intensity formed by a given TDI concentration on MCM 4000 TDI paper tape. No interference effects were observed for the solvents and catalysts studied. |
