Evaluation of a Computer Model Designed to Predict Levels of Isocyanate and Solvent Vapour in Automotive Spray Booths

The Health and Safety Executive (HSE) has developed a computer based predictive model of air pollutant levels during spray application. This is known as MIST (Modelling of Isocyanates and Solvent Transport).

This project has been carried out with the aim of providing the HSE with sufficient experimental data to evaluate the model.

The study was carried out in an automotive down-draught spray booth. Two-pack polyurethane refinish paints of known composition were spray applied to a car body under controlled conditions. Air monitoring was carried out to determine the levels of solvent vapour, isocyanates and total particulates. The paint transfer efficiency and rate of isocyanate reaction was also determined. All experiments were recorded on video.
