| Resumen |
Cases of poisoning due to pyrolysis products of polyurethane (PUR) paints led to a study on the reformation of diisocyanates in the form of poisonous vapours: chemistry, toxicology and pryolysis of PUR paints; design of investigation; results. Commercial polyfunctional hardeners and other paints were decomposed, and the volatile pyrolysis products analysed by gas chromatography. Diisocyanates were reformed in all cases, in varying quantities. Aromatic diisocyanates were more readily released than aliphatic. The possibility of a hazard of thermal decomposition products should therefore always be borne in mind when PUR paints are used. |
