Threshold limit values of mixed solvents - a study of solvents in a 2-pack polyurethane paint (TM-DER-011)

The problem of assigning a Threshold Limit Value for vapour from a mixed solvent system has been investigated by studying a mixture used in a two-pack polyurethane paint. Small-scale painting trials confirm the drying behaviour predicted by evaporation theory. The most volatile solvents will usually constitute the greatest potential health...
